[GitHub] [dubbo] fengxueyun opened a new issue, #10056: consumer 调用并发高，对接口做了短时间（100ms）熔断。consumer服务cpu飙升
fengxueyun opened a new issue, #10056:
URL: https://github.com/apache/dubbo/issues/10056
A服务调用B服务的接口
A服务单机并发500，对调用B服务的接口做了timeout设置100ms。并查看日志发现了大部分超时日志。并且A服务cpu狂飙。
B服务如果100ms只支持并发200左右。是否是由于A服务调用B服务的执行线程实际是没有断开还在执行的原因？

Some perf tools like `Arthas` may help to determine which threads consume so much cpu time
