It's likely that you linked some assemblies that are not Any CPU, but include native code (or are compiled as x86), which cause the entire process to fall back to x86. To understand how your assemblies are compiled, a related Stack Overflow questio…
This post would look into how to tackle and debug issues in scenarios where they only occur in production (or other remote environment) but not in development environment. As anybody who has been in this kind of situation would acknowledge, trying to…
1.cmd窗口中输入emulator -avd test 启动AVD时报错: Running an x86 based Android Virtual Device (AVD) is 10x faster. We strongly recommend creating a new AVD. 这个说的是使用一个x86的模拟器比使用arm内核的要快10倍,所以这只是个提示,让你换成内核为x86的模拟器呢!不换的话你就只能等了,操作每一步都可能要等个好三四秒. 我的是等了6.7分钟界面一直卡着. 2.…
ARM将为苹果开发高性能CPU核心 取代笔记本x86处理器? https://www.cnbeta.com/articles/tech/899421.htm . 之前苹果的哥们说过 谁特别在意自己的软件 终归会自己研发硬件. . 苹果2005年之前用的是 PowerPC架构 之后才换的x86架构.. . x86架构的确有太多的历史包袱 性能和能好过高.. . 这个帖子每年都会出现. 但是也发现arm的性能 的确有了很长远的进步, 很希望arm 能够真正用于数据中心业务 这样国产化也比较好一些.…

http://blog.csdn.net/wangjianno2/article/details/52140936 RISC(reduced instruction set computer,精简指令集计算机)是一种执行较少类型计算机指令的微处理器,起源于80年代的MIPS主机(即RISC机),RISC机中采用的微处理器统称RISC处理器.这样一来,它能够以更快的速度执行操作(每秒执行更多百万条指令,即MIPS).因为计算机执行每个指令类型都需要额外的晶体管和电路元件,计算机指令集越大就会使微处…
在公司经常听其他工程师讲x86,arm平台啥的,作为一个算法工程师,我听过却不知道这是啥!!!(汗颜) 现在偷偷学起: x86,arm,mips等这些都是CPU的架构,不管是手机电脑还是一些嵌入式的设备都需要CPU,但是他们使用的CPU架构是有区别的. x86主要用于PC领域如笔记本.台式机.小型服务器等 arm用于移动领域如手机.平板等 MIPS R系列微处理器用于构建SGI的高性能工作站.服务器和超级计算机系统.在嵌入式方面,MIPS K系列微处理器是目前仅次于ARM的用得最多的处理器之一(…

最近一个客户抱怨他的核心EBS数据库出现性能问题.这是一个10.2.0.3的数据库,运行在Red Hat Enterprise Linux Server release 5.5 (Linux x86-64)操作系统上. 根据客户描述,由于需要维护UPS,他们重启了数据库,结果重启数据库后他们发现只要他们的应用开始连接数据库,那么主机的sys CPU使用率就会变成100%, 但是user CPU使用率几乎是0.而且只要停掉监听或者应用不开启新session连接数据库,这个问题就会消失. 如下是问题…

众所周知,CPU(中央处理单元)是计算机的核心部分,CPU在单位时间内能一次处理的二进制数的位数叫字长,从386.486直到奔腾系列的CPU都是32位,大多数情况32位计算已经能满足现阶段人们的需要.然而随着互联网等技术的发展,对内存的需求越来越大,比如大型服务器,每秒钟处理的数据量就超过2G,32位就难以满足需求了. 按照以前的习惯,我们把基于80x86的CPU架构称作x86结构,这时Intel公司在1978年发其第一块16位的CPU(5MHz 8086)而开发的,1981年IBM推出的第一台…
