测试用例表结构
create table user_info (
id int,
password int,
create_date char(8),
create_time char(9),
mail varchar(30),
phone varchar(15),
address varchar(30),
last_login_ip varchar(15),
user_name varchar(30),
photo varchar(30),

user_level varchar(2),
site varchar(19),
user_type varchar(19),
card_no varchar(16),
card_bank varchar(12),

);

通过oneproxy基于id键采用hash分区分成8张表,每个数据库服务器节点2张

oneproxy启动参数如下
${ONEPROXY_HOME}/oneproxy --keepalive --proxy-address=:3306 \
 --proxy-master-addresses=172.168.10.164:3306@server1 \
 --proxy-master-addresses=172.168.10.165:3306@server2 \

压力语句,基于主键ID随机查询,总并发数440
select last_login_ip from user_info where id=%s;
每个压力服务器基于多进程220个并发

负载情况

数据库端系统负载情况,其中一个节点,其他节点类似



数据库端性能指标

平均每个节点13W左右

一共有4个节点13*4

高峰的时候总QPS达到过55W


oneproxy节点负载情况


压力服务器负载情况



测试总结:

本次测试oneproxy的QPS转发能力以及突破了55W+,并且稳定在50W以上,从系统负载和数据库负载看,理论上还有可优化的空间,oneproxy的四块网卡,每个网卡的流量基本都是在30~50MB左右,ONEPROXY总CPU利用率高峰的时候上过%4800左右,50W的QPS时稳定在%4000左右。oneproxy节点的服务器还有大约8CORE的CPU处理能力,数据库端也大概还有6CORE左右的CPU余量。


我已经将我的环境和相关参数全部发出来了,理论上还有可调优的空间,本人技术有限,期待各位大神给出相关的优化建议,我将根据建议进行尝试,谢谢。
