[jira] [Commented] (PHOENIX-5082) Observations about the Phoenix-Omid integration

    [ https://issues.apache.org/jira/browse/PHOENIX-5082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16729156#comment-16729156 ] 

Lars Hofhansl commented on PHOENIX-5082:
----------------------------------------

1. Committing transactions appears to be extremely slow.

Interestingly this time is spend in HBase batchMutate. See the sampler and profiler screenshots attached.
Committing 100k rows takes over 120s - without transactions it takes about 5s.
