[jira] [Commented] (TS-777) Increasing logbuffer size makes us "drop" log entries

    [ https://issues.apache.org/jira/browse/TS-777?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13044361#comment-13044361 ] 

Leif Hedstrom commented on TS-777:
----------------------------------

What's worse, it seems to affect log collation in severe ways. We should figure out why there are such strong dependencies on the exact value of the log buffers, it would be beneficial to be able to jack these log buffers up significantly on very busy machines.

> Setting proxy.config.log.log_buffer_size higher than somewhere around 24KB makes us start losing log entries. This is bad, since increasing this setting could be a way to increase performance for busy systems. I've for now set the defaults to 16KB, which seems to be stable.
