性能测试

环境:一台2核4G的服务器(华为云 Intel(R) Xeon(R) Gold 6278C CPU @ 2.60GHz)(好像是目前最强的服务器芯片)

代理客户端:connect项目

软件:proxychains-ng iperf3

实验原理: iperf3是专业的测速软件。通过proxychains将iperf3测速的流量走httpproxy,从而测试httpproxy的性能。流量传输如下描述:

iperf3-client ---> connect ---> httpproxy ---> iperf3-server

在测速期间,以上四个进程使用2个cpu核心。

connect的jvm参数:

# 分别为最小堆,最大堆,新生代大小,触发gc的元空间大小(一般是fullgc)两个survivor与eden区比值(=4,则2:4,默认为8即每个survivor为1/10的年轻代大小)
heap_option='-Xms2000m -Xmx2000m -Xmn600m -XX:MetaspaceSize=40M -XX:SurvivorRatio=8'

httpproxy的jvm参数:

# 分别为最小堆,最大堆,新生代大小,触发gc的元空间大小(一般是fullgc)两个survivor与eden区比值(=6,则2:6,默认为8即每个survivor为1/10的年轻代大小)
heap_option='-Xms2000m -Xmx2000m -Xmn600m -XX:MetaspaceSize=40M -XX:SurvivorRatio=8'

从GC日志上看,没有看到fullGC,为减少youngGC,年轻代的大小刻意地设置地比较大,副作用用jvm占用的内存比较大(500MB,来自top的res字段),实际使用场景下,并不需要这么大的年轻代。

性能测试结果

HttpProxy上行速度(iperf3 295秒测试结果):10.1 Gbits/sec ——单线程单tcp连接跑满万兆网卡
