[jira] [Commented] (CASSANDRA-15448) Throttle the speed of
merkletree row hash
[ https://issues.apache.org/jira/browse/CASSANDRA-15448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16994898#comment-16994898 ]
David Capwell commented on CASSANDRA-15448:
-------------------------------------------
Do you have any profiles/gc logs to show where you are seeing most of the time? There is some work going on to make repair more efficient; work to remove allocations (less GC), work to speed up interval trees (see CASSANDRA-15397), change implementation of hash (see CASSANDRA-15294), etc. With all those applied, wonder how it would impact on your systems.

> Under our enviroment , we may got some Low-profile servers, like 4core 8G memory, so when doing repair for merkletree calculate , the cpu may cost so much. And we think repair can take long time so do some speed throttle may increase repair timeļ¼but can make the server more stable.
