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 :)
