[jira] [Updated] (HDDS-3744) Improve OM performance with 1.75% by
avoid String.toUpperCase
[ https://issues.apache.org/jira/browse/HDDS-3744?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
runzhiwang updated HDDS-3744:
-----------------------------
Description:
I start a ozone cluster with 1000 datanodes, and run two weeks with heavy workload, and perf om.
You can find NetUtils.normalize cost 4.83% cpu, because it needs to do Matcher.replaceAll, we need not to do this when getFromProtoBuf, scm can do NetUtils.normalize and keep the result in memory, then pass the result to om.
