Description

环境:200Gb RDMA网络
客户端:FUSE版本3.16.1 ,用的fio压测客户端,引擎是usrbio
操作:有两个客户端节点,分别用fio压测,fuse客户端的配置保持一致
现象:一个客户端的带宽只能跑到15GB,而另一个客户端能跑到25GB。25GB的节点只要不重启fuse客户端怎么测都是极好的,但是如果重启,也有很大概率变成像第一个客户端那样15GB的带宽。比较奇怪,也就是说只要客户端挂载之后,一开始能跑到25GB,以后测也会25GB的, 如果一开始只能跑15GB,那以后也就只能跑15GB。并且和协程与线程池线程的数量无关

大家遇到过这种现象吗,或者能给一些思路吗,因为用到wait的地方太多了
