memcached几个客户端测试

liwya

http://code.google.com/p/memcached/wiki/Clients
分别建立五个测试页面：
xmem.jsp使用xmemcached-1.3.2.jar
spymem.jsp使用memcached-spy-2.6rc1.jar
mem.jsp使用官方memcached-2.5.0.jar
alimem.jsp使用alisoft-xplatform-asf-cache-2.5.1.jar
index.jsp单纯页面
并发1000测试
[tomcat@localhost ~]$ webbench -c 1000 -t 60 http://127.0.0.1:7001/xmem.jsp
1000 clients, running 60 sec.

把官方包的连接参数修改为setMaxConn(2500) 运行mem.jsp结果：
[tomcat@localhost ~]$ webbench -c 10000 -t 60 http://127.0.0.1:7001/mem.jsp
10000 clients, running 60 sec.
Speed=322014 pages/min, 4100560 bytes/sec.
Requests: 291066 susceed, 30948 failed.
说明通过参数优化，这样的性能就很接近使用nio的xmemcached了
