我在网上找的一个对抗测试（by TimYang大牛）：

http://timyang.net/data/mcdb-tt-redis/

我拿TreapDB跑了一下：
小数据：写42517每秒，读：39098每秒
大数据：写4599每秒：读：3838每秒

我这里的key是顺序产生的,不知道Tim的key是乱序的还是顺序的�
��

测试代码（写）：

{{{
from thrift import Thrift
from thrift.transport import TTransport
from thrift.transport import TSocket
from thrift.protocol.TBinaryProtocol import TBinaryProtocolAccelerated
from pytreap import TreapDBService
from pytreap.ttypes import *
import string
import time
import random

def main():
    socket = TSocket.TSocket("localhost", 11812)
    transport = TTransport.TBufferedTransport(socket)
    protocol = TBinaryProtocol.TBinaryProtocolAccelerated(transport)
    client = TreapDBService.Client(protocol)
    transport.open()
    data = 'x'*100
    count = 5000000 
    t1 = time.time()
    buffer = {}
    for i in xrange(count):
        buffer[str(i)] = data
        if i%3000 == 0:
            client.bulkPut(buffer)
            buffer = {}
        if i% 100 == 0:
            print i
    transport.close()
    t2 = time.time()
    print (count+0.0)/(t2-t1)

if __name__ == "__main__":
    main()

}}}

Tim的测试每个key的区分度很大，都是数字。所以按照个测试��
�结果比我原先的benchmark高出好多(我原先的bechmark中都带"thing"
这个前缀，而且数字的范围更广)，真是令人高兴。性能至少�
��MemcacheDB(注意，不是memcached)要好。

大小数据分别是多少k？

小数据100 bytes , 大数据20k bytes。
测试程序在上面给出来了，key是顺序产生的，使用了批量插��
�。
内存映射分配为320M(如上述配置文件)
