[asterisk-bugs] [JIRA] (ASTERISK-22488) CDR performance bottleneck

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-22488?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=210219#comment-210219 ] 

Matt Jordan commented on ASTERISK-22488:
----------------------------------------

Creating the candidates from the channels in the bridge could certainly be done more efficiently.

This really needs a two pass look-up: One to get the channels that are in the bridge, the next to get their CDRs from the existing container. That really should prevent the O(n) iteration that occurs currently.

> Repeatedly doing a local channel chain of 300 eventually causes the system to be bogged down doing CDR processing.
> It would appear that create_candidates_for_bridge() needs to be improved since the number of buckets in the the active_cdrs_by_channel container was increased.
