LevelDB.NET性能测试

最近了解了一下LevelDB,发觉这个嵌入式的K-V数据性能不错,所以顺便想在使用层面了解一下.由于LevelDB也有针对.net的实现,所以就针对了LevelDB.NET进行了一个简单的读写压力测试.为了更客观的体现测试结构所以添加了大量的数据,和GET操作的时候随机已经有的KEY进行.

Set操作

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

public static void WriteTest(object state)         {             while (true)             {                   User user = new User();                 string id = GetKey().ToString("000000000000000000000");                 user.Name = id;                 user.EMail = id + "@msn.com";                 user.CrateTime = DateTime.Now;                 user.City = "GZ" + id;                 user.Country = "CN" + id;                 user.Address = "sdfffffffffffffffffffffffffafjsdfjsljfsjfls"+id;                 user.Phone = id;                 user.Region = "gd";                 db.Set(user.Name, user);                 System.Threading.Interlocked.Increment(ref mCount);               }         }

Get操作

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

while (true)             {                 User user;                   int index = ran.Next(100000, 500000);                 if (index == li)                 {                     Console.WriteLine(index);                 }                 li = index;                   user = db.Get<User>(index.ToString("000000000000000000000"));                 System.Threading.Interlocked.Increment(ref mIndex);                 System.Threading.Interlocked.Increment(ref mCount);               }

总结

LevenDB.Net的写入速度非常高效,在单线程写入的情况都可以达到接近5W/秒的效率,而在获取上的效率更高5线程的并发读竟然可以达到15W/秒的能力....这读效果是相当的可观.
