Mauritz Lovgren commented on DIRMINA-681: ----------------------------------------- I will perform profiling this week to identify the source of the CPU peaks... > Strange CPU peak occuring at fixed interval when several thousand connections > active > ------------------------------------------------------------------------------------ > > Key: DIRMINA-681 > URL: https://issues.apache.org/jira/browse/DIRMINA-681 > Project: MINA > Issue Type: Task > Components: Core > Affects Versions: 2.0.0-M4 > Environment: Windows Vista Ultimate 64-bit (on 64-bit Sun JDK > 1.6.0_12). Intel Core 2 Quad Core Q9300 2,5 GHz, 8 GB RAM > Reporter: Mauritz Lovgren > Fix For: 2.0.0 > > Attachments: screenshot-1.jpg, screenshot-2.jpg, screenshot-3.jpg > > > Observing strange CPU activity occuring at regular (seemingly fixed) interval > with no protocol traffic activity. > See attached window capture of task manager that shows this with 3000 active > connections. > Is there some kind of cleanup occuring within MINA core at a predefined > interval? > The 3000 connections in the example above connects within 250 seconds. A > normal situation would be that these connections are established over a > longer period of time, perhaps spreading the CPU peaks shown above as well, > flattening the curve. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
