     [ https://issues.apache.org/jira/browse/HBASE-8680?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jeffrey Zhong updated HBASE-8680:

    Attachment: hbase-8666-v3.patch

[~tedyu@apache.org] Thanks for the good catch! In V3, I fixed the TestSplitLogWorker because
it taks a little bit longer for it start due to a new connection creation.

> The JIRA is to check in changes to address performance issues found during my performance
testing as following:
> 1) When WALEdits belongs to a region which split/merged later incur extra waitUntilRegionOnline
RPC call
> 2) Using a single shared connection for replaying archives better performance. Everytime
creating a new connection, it incurs 4+ seconds to establish a connection to ZK.
> 3) other small modifications to mitigate excessive logging
