C#中使用多款LevelDB.Net封装测试性能

一、使用http://www.nuget.org/packages/LevelDB.NET 测试

　　1、新建项目，并Nuget引入库：

　　　　

　　2、写代码

using LevelDB;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace LevelDBDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            WriteTest();
        }
        public static void WriteTest()
        {
            var db = LevelDB.DB.Open("c:\\works\\mydb", new Options { CreateIfMissing = true });

            System.Diagnostics.Stopwatch sp = new System.Diagnostics.Stopwatch();
            sp.Reset();
            sp.Start();
            long mCount = ;
            while (true)
            {
                db.Put(WriteOptions.Default, Guid.NewGuid().ToString(), "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaeraaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb");
                if (System.Threading.Interlocked.Increment(ref mCount) %  == )
                {
                    Console.WriteLine("{0} has inserted. time use {1}ms.", mCount, sp.ElapsedMilliseconds);
                }
            }
        }
    }
}

　　3、看效果：我的机器上配置不怎么好，大约5000条/秒。

二、修改引用库：

　　http://www.meebey.net/projects/leveldb-sharp/

　　https://github.com/meebey/leveldb-sharp

　　注意，需要把leveldb.dll放在程序目录下。这个文件可以通过下载https://www.nuget.org/packages/LevelDB.Net/ 中的dll，然后反编译，取得里面的资源。

　　同时引入：

　　2、代码和前面的相同

　　3、运行结果：

　　

　　

　　效果还不错，大约是6.6w条/秒。
