[jira] [Commented] (HTTPCLIENT-1117) CPU spike

    [ 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.
