Subject [jira] [Commented] (HBASE-6925) Change socket write size from 8K to 64K for HBaseServer
Date Thu, 01 Nov 2012 18:57:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13488928#comment-13488928
] 

Lars Hofhansl commented on HBASE-6925:
--------------------------------------

I'd definitely be interested in the various changes that went into this.

HBASE-4956 just fixes Result.readFields to read the resultbuffer in 8k chunks?
Would that defeat the purpose of this change?

I can do some quick test on a single host, but that won't be very representative.

> Creating a JIRA for this, but the change is trivial: change NIO_BUFFER_LIMIT from 8K
to 64K in HBaseServer. This seems to increase scan throughput.
