[JBoss JIRA] (MODCLUSTER-471) Mod_cluster performance on httpd 2.4

by Jean-Frederic Clere (Jira)

[ https://issues.jboss.org/browse/MODCLUSTER-471?page=com.atlassian.jira.pl... ] Jean-Frederic Clere closed MODCLUSTER-471. ------------------------------------------ Resolution: Out of Date > Mod_cluster performance on httpd 2.4 > ------------------------------------ > > Key: MODCLUSTER-471 > URL: https://issues.jboss.org/browse/MODCLUSTER-471 > Project: mod_cluster > Issue Type: Bug > Components: Native (httpd modules) > Affects Versions: 1.3.1.Final > Reporter: Coty Sutherland > Assignee: Jean-Frederic Clere > Priority: Major > Attachments: reproducer.tar.gz > > > When using mod_cluster with httpd 2.4 (specifically with the JWS 3.0.1 product family) in front of EAP 6.3 there is a noticeable performance decrease in requests being serviced from httpd. This seemingly is resolved by using the latest (at presently 1.3.2.Alpha), but research hasn't pointed to a specific fix there, so I'm opening this. We were thinking that it had something to do with module loading order, but haven't been able to confirm that. > One more important note is that the user is fronting about 250+ (up to 290) JBoss instances behind a single balancer. I'm attaching the reproduction script that the user provided. It needs a receiver (a mod_cluster node running on localhost port 8009) and an httpd balancer. Then you can run the create script to create the nodes and the update script to update them using netcat to prevent the need for 250 real instances. It is a bit hacky, but it could save you some resources. -- This message was sent by Atlassian Jira (v7.12.1#712002)
