怎么调试lua性能

我们的游戏使用的是Cocos2dx-lua 3.9的项目，最近发现我们的游戏。运行比较缓慢。想做一次性能优化了。其实主要分为GPU、CPU的分别优化。GPU部分的优化。网上有很多优化措施。但是CPU因为是每个项目都不一样所以也没有什么特别的通用的优化手段。软件运行的速度毕竟跟你的代码质量是直接挂钩的。常规的Lua优化方式。也就是很多地方在提的公共函数的本地化。比如说`local type = type`这种。不过在后来的调查中发现这种方式对于lua5.1效果比较明显。至于5.3或者luaJIT则效果不是很明显。调查中发现3.9是使用luaJIT的（想知道自己的项目解释器是不是Jit应该可以print(jit and jit.version)）。所以这部分我们就暂时不做了。只能从项目中设计不合理的部分改起了。但是从什么地方开始改。那些函数调用的时间比较长，就需要来统计函数的运行次数与时间了。

怎么统计每个函数的运行时间和次数

网上找了找相关资料，就这篇文章写的还算明白。lua性能分析。不过我并没有找到他的代码，因为Github上的这个项目好像是丢了，不知道为什么。不过大体意思是明白怎么回事了。简单点说就是在C++层面上通过两个回调（函数进入时、退出时）然后统计时间，然后根据执行的先后顺序来一层一层的打印对应的对战，达到游戏中所有的函数运行时间心中有数的目的。因为没有找到他的源码。不过好在读懂他是什么意思了。不过我对于Lua C++部分的代码并不是很熟，所以我决定在Lua方面做手脚，统计函数的执行时间究竟有多长，毕竟可以打到同样的目的，不过Lua统计时间看看就好。不要太当真。

怎样给Lua的函数添加上统计代码

或许对于其他语言来说这件事情没有那么容易，不过对于lua语言来说这就简单多了。最简单的手段就是让原来的函数等于一个新的函数。在新的函数中计时并且调用原来的函数就可以了。废话不多说了。直接上相关代码可能更容易看懂

local function PerformanceStatisticsFunction(key, func)

    -- print("PerformanceStatisticsFunction", key)

    return function( ... )

        local current_stack = nil

        local parent_stack = PerformanceStatistics:getInstance()._stack_parent

        local call_stack = PerformanceStatistics:getInstance()._call_stack

        if not parent_stack then

            if not call_stack[key] then

                call_stack[key] = kunpo.TreeNode.new()

            end

            current_stack = call_stack[key]

        else

            current_stack = parent_stack:getChildByName(key)

            if not current_stack then

                current_stack = kunpo.TreeNode.new()

                parent_stack:addChild(current_stack)

            end

        end

        current_stack:setName(key)

        local data = current_stack:getData()

        if data == nil then

            data = {Count = 0, Time = 0}

            current_stack:setData(data)

        end

        PerformanceStatistics:getInstance()._stack_parent = current_stack

        local t0 = GetTimeNow()

        local res = {func(...)}

        local t1 = GetTimeNow()

        PerformanceStatistics.getInstance():statisticsTime(key, t1 - t0)

        PerformanceStatistics.getInstance():statisticsCount(key)

        data.Count = data.Count + 1

        data.Time = data.Time + (t1 - t0)

        PerformanceStatistics:getInstance()._stack_parent = parent_stack

        return unpack(res)

    end

end

然后就是准备需要监控的数据了

因为项目中的代码多是写到一个类似于类概念的地方所以我们这边准备的都是相关内容的类内容

-- 初始化项目中的函数

local WatchItem =

{

    ["Manager.ArchiveManager"] = kunpo.ArchiveManager,

    ["Manager.BasicDataManager"] = kunpo.BasicDataManager,

    ["Manager.BuffManager"] = kunpo.BuffManager,

    ["Manager.BuffTypeManager"] = kunpo.BuffTypeManager,

    ["Manager.ConfigDataManager"] = kunpo.ConfigDataManager,

    ["Manager.EffectsManager"] = EffectsManager,

    ["Manager.GameManager"] = GameManager,

    ["Manager.LevelManager"] = LevelManager,

    ["Manager.MachineManager"] = MachineManager,

    ["Manager.MapManager"] = MapManager,

    ["Manager.ObjectManager"] = ObjectManager,

    ["Manager.PerCreateManager"] = kunpo.PerCreateManager,

    ["Manager.PerLoadingManager"] = kunpo.PerLoadingManager,

    ["Manager.PortalManager"] = PortalManager,

    ["Manager.RecycleManager"] = RecycleManager,

    ["Manager.RuntimeDataManager"] = kunpo.RuntimeDataManager,

    ["Manager.ShadowManager"] = ShadowManager,

    ["Manager.TaskManager"] = kunpo.TaskManager,

    ["Manager.TaskUIManager"] = TaskUIManager,

    ["Manager.TCDataManager"] = kunpo.TCDataManager,

    ["Manager.UpdateManager"] = kunpo.UpdateManager,

    ["Manager.UpdateWeightManager"] = kunpo.UpdateWeightManager,

}

-- 添加监控内容

local table_list =

{

    ["kunpo.Components"] = kunpo.Components,

    ["kunpo.DataPool"] = kunpo.DataPool,

    ["kunpo.Effects"] = kunpo.Effects,

    ["kunpo.GameData"] = kunpo.GameData,

    ["kunpo"] =

    {

        ["Bullet"] = kunpo.Bullet,

        ["Character"] = kunpo.Character,

        ["DropItem"] = kunpo.DropItem,

        ["Enemy"] = kunpo.Enemy,

        ["MachineBase"] = kunpo.MachineBase,

        ["LimitCondition"] = kunpo.LimitCondition,

        ["LimitLevel"] = kunpo.LimitLevel,

        ["LimitSourceChildType"] = kunpo.LimitSourceChildType,

        ["LimitSourceItemId"] = kunpo.LimitSourceItemId,

        ["LimitSourceType"] = kunpo.LimitSourceType,

        ["LimitTargetChildType"] = kunpo.LimitTargetChildType,

        ["LimitTargetItemId"] = kunpo.LimitTargetItemId,

        ["LimitTargetType"] = kunpo.LimitTargetType,

        ["PreConditionLossBlood"] = kunpo.PreConditionLossBlood,

        ["AStar"] = kunpo.AStar,

        ["CommonsLogics"] = kunpo.CommonsLogics,

        ["EventTools"] = kunpo.EventTools,

        ["functions"] = kunpo.functions,

        ["RouteData"] = kunpo.RouteData,

        ["SafeCall"] = kunpo.SafeCall,

        ["SDKHelper"] = kunpo.SDKHelper,

        ["SpriteHelper"] = kunpo.SpriteHelper,

        ["TimeRecord"] = kunpo.TimeRecord,

    },

    ["_G"] =

    {

        ["Joystick"] = Joystick,

        ["JoystickShot"] = JoystickShot,

        ["Linq"] = Linq,

    },

    ["kunpo.BarrierTools"] = kunpo.BarrierTools,

    ["kunpo.Random"] = kunpo.Random,

}

for key, list in pairs(table_list) do

    for k,v in pairs(list) do

        WatchItem[key.."."..k] = v

    end

end

for k, item in pairs(WatchItem) do

    PerformanceStatisticsTable(k, GetSourceClass(item))

end

不过在添加的时候可能会加载不上，因为Cocos2dx-lua中的类中的函数，并不是在他的类上。而是在他的类似于父类的地方。所以需要想办法获取到他的原始父类，将监控代码加载到他的原始父类中去才可以

local function GetSourceClass(t)

    local data = t

    while true do

        if not t then

            break

        end

        if rawget(t, "__cname") then

            break

        end

        local class = rawget(t, "class")

        if class then

            data = class

            break

        end

        local mtable = getmetatable(t)

        if mtable == nil then

            break

        end

        local index = rawget(mtable, "__index")

        if type(index) ~= "table" then

            break

        end

        data = GetSourceClass(index)

        break

    end

    return data

end

类的初始化实际上就是替换类中的函数为统计函数

local function PerformanceStatisticsTable(tname, t)

    -- print("PerformanceStatisticsTable", tname)

    -- local PrintName = "Manager.ObjectManager"

    -- if tname == PrintName then

    --     print("PerformanceStatisticsTable", tname, t, t.__is_performance_statistics)

    -- end

    local ignore_list = {"ctor", "new", "create"}

    while true do

        if t.__is_performance_statistics then

            break

        end

        t.__is_performance_statistics = true

        for k,v in pairs(t) do

            -- if tname == PrintName then

            --     print(PrintName, k, v)

            -- end

            local item_type = type(v)

            if item_type == "function" and not table.contain(ignore_list, k) then

                t[k] = PerformanceStatisticsFunction(table.concat({tname, k}, "."), v)

            end

        end

        break

    end

end

这些东西都做好了之后。就差统计相关的信息。需要有地方将这一帧中的所有性能调试相关的信息保存起来

local function GetTimeNow()

    return os.clock()

end 

local output_path = device.writablePath.."Debug"

local lfs = lfs

for file in lfs.dir(output_path) do

    if file ~= "." and file ~= ".." and file ~= ".DS_Store" then

        -- print("DebugOutput", file)

        local file_name = output_path.."/"..file

        os.remove(file_name)

    end

end

local PerformanceStatistics = class("PerformanceStatistics")

local instance = nil

function PerformanceStatistics:getInstance()

    return instance

end

function PerformanceStatistics:ctor( ... )

    self._statistics_time = {}

    self._statistics_count = {}

    self._all_time = 0

    self._print_index = 1000000

    self._call_stack = {}

    self._stack_parent = nil

    -- self._all_time_label = nil

end

-- function PerformanceStatistics:setAllTimeLabel(label)

--      self._all_time_label = label

-- end

function PerformanceStatistics:statisticsTime(name, time)

    self._statistics_time[name] = (self._statistics_time[name] or 0) + time

end

function PerformanceStatistics:statisticsCount(name)

    self._statistics_count[name] = (self._statistics_count[name] or 0) + 1

end

function PerformanceStatistics:clearLastInfo()

    -- if self._all_time_label then

    --     self._all_time_label:setString(self._all_time)

    -- end

    self._statistics_time = {}

    self._statistics_count = {} 

    -- for k,v in pairs(self._statistics_time) do

    --     self._statistics_time[k] = 0

    -- end

    -- for k,v in pairs(self._statistics_count) do

    --     self._statistics_count[k] = 0

    -- end

    self._call_stack = {}

    self._stack_parent = nil

    self._all_time = 0

end

function PerformanceStatistics:setAllTime(t)

    self._all_time = t

end

function PerformanceStatistics:getAllTime()

    return self._all_time

end

local HeadTab = 3

local function WriteTreeToFile(node, parenttime, deep)

    deep = deep or 0

    local heads = {}

    for i = 1, deep do

        table.insert(heads, "\t")

    end

    local alltime = PerformanceStatistics:getInstance()._all_time

    local data = node:getData()

    io.write(table.concat(heads)..table.concat({string.format("%.3f\t%.3f", data.Time / parenttime, data.Time / alltime), data.Count, node:getName()}, "\t").."\n")

    local childs = node:getChilds()

    table.sort(childs, function(a, b) return a:getData().Time > b:getData().Time end)

    for _, item in ipairs(childs) do

        WriteTreeToFile(item, data.Time, deep + 1)

    end

end

function PerformanceStatistics:writeAllInfoToFile()

    self._print_index = self._print_index + 1

    local file_path = device.writablePath.."Debug/"..self._print_index..".txt"

    io.output(file_path)

    io.write("self._all_time "..self._all_time.."\n")

    -- 瀑布式打印

    local alltime = PerformanceStatistics:getInstance()._all_time

    for _, item in pairs(self._call_stack) do

        WriteTreeToFile(item, alltime)

        io.write("\n")

    end

    -- 普通打印

    io.write("\nself._statistics_time \n")

    local output_list = {}

    for k,v in pairs(self._statistics_time) do

        table.insert(output_list, {key = k, value = v})

    end

    table.sort(output_list, function(a, b) return a.value > b.value end)

    for i, item in ipairs(output_list) do

        local k, v = item.key, item.value

        io.write(table.concat({v / self._all_time, v, k}, "\t") .. "\n")

    end

    io.write("\nself._statistics_count \n")

    output_list = {}

    for k,v in pairs(self._statistics_count) do

        table.insert(output_list, {key = k, value = v})

    end

    table.sort(output_list, function(a, b) return a.value > b.value end)

    for i, item  in ipairs(output_list) do

        local k, v = item.key, item.value

        io.write(table.concat({v, k}, "\t") .. "\n")

    end

end

instance = PerformanceStatistics.new()

cc.exports.PerformanceStatistics = PerformanceStatistics

重写主循环

最后重写掉主循环，让主循环每帧统计信息，并且在当前帧超时之后输出当前帧的所有信息。

local kunpo_components_battlestate_runingupdate = kunpo.Components.BattleState.RuningUpdate

kunpo.Components.BattleState.RuningUpdate = function( ... )

    PerformanceStatistics.getInstance():clearLastInfo()

    local t0 = GetTimeNow()

    kunpo_components_battlestate_runingupdate(...)

    local t1 = GetTimeNow()

    PerformanceStatistics.getInstance():setAllTime(t1 - t0)

    if t1 - t0 > 0.008 then

        PerformanceStatistics.getInstance():writeAllInfoToFile()

    end

end

怎么查看最后的输出信息

我想最好还是先来一个范本最好

这段信息分成了三段：

  • 第一段是调用的树型输出，可以知道他们之间的调用关系。每个函数占用父节点的时间比例，占用总时间的时间比例、调用次数、函数名称
  • 第二阶段是总共的函数调用时长比例。如果某个函数调用的时间太长。要么就是他被调用的次数很多，要么就是他的实现比较垃圾
  • 第三阶段是总共的函数调用次数排序。如果某一个函数调用次数比较多，那么可以考虑减少这个函数的调用次数。方法可以自己想。

啊，还忘了树形结构的实现

local TreeNode = class("TreeNode")

function TreeNode:ctor()

	self._parent = nil

	self._childs = {}

	self._name = nil

	self._data = nil

end

function TreeNode:setName(v)

	self._name = v

end

function TreeNode:getName()

	return self._name

end

function TreeNode:setParent(v)

	self._parent = v

end

function TreeNode:getParent()

	return self._parent

end

function TreeNode:addChild(v)

	table.insert(self._childs, v)

end

function TreeNode:getChilds()

	return self._childs

end

function TreeNode:getChildByName(name)

	local data = nil

	for _, item in ipairs(self._childs) do

		if item:getName() == name then

			data = item

			break

		end

	end

	return data

end

function TreeNode:clearChilds()

	self._childs = {}

end

function TreeNode:setData(v)

	self._data = v

end

function TreeNode:getData()

	return self._data

end

kunpo.TreeNode = TreeNode

return TreeNode

这个很简单的，我就不说了。

最后真的抱歉，我回头想想。我还是没有办法。非常顺畅的描述这个问题怎么解决。写作水平真的有限，凑合看吧。
