Out of curiosity what tools do you use for profiling and finding these sorts of things? Plain old xdebug, xhprof, or other things? I'm going to have to jump into debugging a fairly large Symfony application within the next couple months and am on the look out for good tools to help me along.

Traditionally xdebug/xhprof were pretty decent, but xhprof has been a bit abandoned since facebook uses HHVM now.

There are two new commercial condenters though that came out in the last few months: Blackfire.io and QafooLabs.com

Both have announced support for showing GC time in profiles as a result of today's noise :) https://twitter.com/beberlei/status/539816149303955456 https://twitter.com/symfony_en/status/539815082881187841

Xhprof is maintained by Phacility. They did pick up on this[1], but it's not as easy as one might think.

Thanks for the correction, I wasn't aware that was part of what phabricator extracted out of facebook :)

Thanks for the info, those two will be very helpful.
