imay commented on issue #242: Poor query performance under high concurrence URL: https://github.com/apache/incubator-doris/issues/242#issuecomment-429767394 @kangkaisen When SQL3 running, was CPU idle is zero? If there already has more CPU resource, I think that this may be not CPU bottleneck, then using perf may not find the reason. For example, there may be some lock which all query want to held, or some thread pool is full.
