Subject [jira] [Commented] (HTTPCLIENT-1117) CPU spike
Date Fri, 19 Aug 2011 19:06:27 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1117?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13087902#comment-13087902

Oleg Kalnichevski commented on HTTPCLIENT-1117:
-----------------------------------------------

There are no known performance issues with HttpClient 4.1.x. Without additional details as
to where exactly in the HttpClient code those spikes seem to occur, I'll have no other choice
but to close this issue as can't reproduce. All I can recommend at this point is make sure
no deprecated methods are used anywhere in your application code and to collect more details
about the issue I could act upon.

> I was upgrading from HttpClient 4.0.1 to 4.1.2.   Everything worked OK but when I deployed
to production JBoss started using all the CPU on the box with moderate load.    Typically,
jboss would only use 10% of the cpu.   The only thing that change was the HttpClient.
