[jboss-jira] [JBoss JIRA] Updated: (JBCLUSTER-131) Evaluate impact of message bundling in HttpSession replication performance
[ http://jira.jboss.com/jira/browse/JBCLUSTER-131?page=all ]
Brian Stansberry updated JBCLUSTER-131:
---------------------------------------
Attachment: bundleeffect.xls
Updated bundleeffect.xls with results using different granularities (and thus different
numbers of requests per second.) UDP transport. See GRANULARITY - UDP worksheet for
details. Results were consistent with the previous results.
With REPL_SYNC, disabling bundling seems helpful with lower numbers of requests per
second; once req/s get high bundling actually improves performance.
With REPL_ASYNC, the effect of disabling bundling is inconsistent, but generally somewhat
negative.

Issue Type: Task
Security Level: Public(Everyone can see)

As described in http://wiki.jboss.org/wiki/Wiki.jsp?page=ProblemAndClusterRPCs the use of
message bundling is not optimal for RPC calls. Essentially all clustering traffic in the
AS is RPC calls, so we should evaluate the impact of disabling message bundling.
I'm going to evaluate this using both REPL_SYNC and REPL_ASYNC. Any negative effect
of bundling with REPL_ASYNC should be less, as the caller does not wait for the response.
