LevelDB.NET性能測試，

LevelDB.NET性能測試，

    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.由於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.

public static void WriteTest(object state)

                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);

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線程的並發讀竟然可以達到15W/秒的能力....這讀效果是相當的可觀.
