SanmuWangZJU commented on issue #3127: CPU LOAD more than 300% URL: https://github.com/apache/incubator-shardingsphere/issues/3127#issuecomment-535769156 Thread globalThreadPoolSlave takes most of CPU resource, are they all hang at 'org.apache.shardingsphere.core.parse.cache.SQLParseResultCache#getSQLStatement'? org.apache.shardingsphere.core.parse.cache.SQLParseResultCache#cache is not thread safe or thread local, maybe this is related with your problem (you can replace the cache with a thread safe cache like guava cache and test again) ?
