redis和ssdb的简单性能测试

公司的缓存服务是redis和ssdb搭配使用的。

ssdb是跟redis类似的缓存服务器。但是redis是基于内存的，ssdb是基于文件系统的。这是ssdb的一大亮点。在ssdb的官网上看到二者的性能相差无几，于是在公司的一台测试机上对二者的性能做了一下简单测试。

测试内容为：10w次set，get，hset，hget请求所花费的时间。

虽然没有像官网那么出色，但是也不错了。

测试代码如下：

#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import redis
from ssdb import SSDB
import time
r = redis.Redis(host='localhost', port=6379)
s = SSDB(host='localhost', port=8888)
def testRedisSet():
    count=0
    start=time.time()
    while count<100000:
        r.set("test","xxxxxxxxxxxxxxxxxxxxx")
        count=count+1
    print "redis set:%f s"%(time.time()-start)
def testSsdbSet():
    count=0
    start=time.time()
    while count<100000:
        s.set("test","xxxxxxxxxxxxxxxxxxxxx")
        count=count+1
    print "ssdb set:%f s"%(time.time()-start)
def testRedisGet():
    count=0
    start=time.time()
    while count<100000:
        r.get("test")
        count=count+1
    print "redis get:%f s"%(time.time()-start)
def testSsdbGet():
    count=0
    start=time.time()
    while count<100000:
        s.get("test")
        count=count+1
    print "ssdb get:%f s"%(time.time()-start)
def testRedisHSet():
    count=0
    start=time.time()
    while count<100000:
        r.hset("htest","htest","xxxxxxxxxxxxxxxxxxxxx")
        count=count+1
    print "redis hset:%f s"%(time.time()-start)
def testSsdbHset():
    count=0
    start=time.time()
    while count<100000:
        s.hset("htest","htest","xxxxxxxxxxxxxxxxxxxxx")
        count=count+1
    print "ssdb hset:%f s"%(time.time()-start)
def testRedisHget():
    count=0
    start=time.time()
    while count<100000:
        r.hget("htest","htest")
        count=count+1
    print "redis hget:%f s"%(time.time()-start)
def testSsdbHget():
    count=0
    start=time.time()
    while count<100000:
        s.hget("htest","htest")
        count=count+1
    print "ssdb hget:%f s"%(time.time()-start)
