Bruce J Schuchardt reassigned GEODE-7920:
-----------------------------------------
Assignee: Bruce J Schuchardt
> Geode UDP INT thread found processing cache operations
> ------------------------------------------------------
>
> Key: GEODE-7920
> URL: https://issues.apache.org/jira/browse/GEODE-7920
> Project: Geode
> Issue Type: Improvement
> Components: membership, messaging
> Reporter: Bruce J Schuchardt
> Assignee: Bruce J Schuchardt
> Priority: Major
>
> While looking into another problem in a test run with disable-tcp=true I
> found this JGroups thread processing a cache operation in-line. These
> threads should never process cache ops. They exist just to read messages and
> hand them off to an Executor.
> Fixing this should improve UDP messaging performance somewhat.

> unicast-reader thread and the multicast-reader thread.
