最近了解了一下LevelDB,發覺這個嵌入式的K-V數據性能不錯,所以順便想在使用層面了解一下.由于LevelDB也有針對.net的實現,所以就針對了LevelDB.NET進行了一個簡單的讀寫壓力測試.為了更客觀的體現測試結構所以添加了大量的數據,和GET操作的時候隨機已經有的KEY進行.

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);               }

總結

        LevenDB.Net的寫入速度非常高效,在單線程寫入的情況都可以達到接近5W/秒的效率,而在獲取上的效率更高5線程的并發讀竟然可以達到15W/秒的能力....這讀效果是相當的可觀.
