If for whatever reason, packaging becomes a bottleneck, we can also try \u003ctt class=\"remarkup-monospaced\"\u003etideways_xhprof\u003c\/tt\u003e, which is a popular xhprof fork that supports PHP 7, and actually has already been published on Debian. \u003ca href=\"https:\/\/packages.debian.org\/stretch\/php-tideways\" class=\"remarkup-link\" target=\"_blank\" rel=\"noreferrer\"\u003ehttps:\/\/packages.debian.org\/stretch\/php-tideways\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003eAnyhow, one way or another, it seems the story for debug profiling is fairly straight forward.\u003c\/p\u003e\n\n\u003cp\u003eMore difficult is the sampling profiler. For that we currently use HHVM Xenon.

There is good support for perf (and perf maps) for various interpreters that use compiled code. Chrome V8 (via Node.js) works fine with it, and HHVM works well with it as well.

I used it mainly to show that we don't want to use that on any portion of production traffic. It has high overhead, but the results are worth it, given its use case for manual profiling by developers.

production, I used the following cURL request to obtain a few FlameGraph-compatible lines from XHProf's sampling mode:\u003c\/p\u003e\n\n\u003cdiv class=\"remarkup-code-block\" data-code-lang=\"console\" data-sigil=\"remarkup-code-block\"\u003e\u003cpre class=\"remarkup-code\"\u003e\u003cspan class=\"gp\"\u003e$ curl -i -H 'X-Wikimedia-Debug: backend=mwdebug1001.eqiad.wmnet; sampleprofiler' 'https:\/\/en.wikipedia.org\/w\/index.php?title=Main_Page&useskin=minerva&uselang=nl&debugger=T176916'\u003c\/span\u003e\u003c\/pre\u003e\u003c\/div\u003e\n\n\u003cp\u003eIn most cases, the sampling interval of 0.1s used by XHProf means that generally you only get 1 or 2 frames on a typical request. But when using the Main_Page (which is fairly complex), and a combination of skin\/language not recently used on the same server, it'll take longer and produce 20-30 frames.\u003c\/p\u003e\n\n\u003cp\u003eUsing the above example, I got the following output:\u003c\/p\u003e\n\n\u003cdiv class=\"remarkup-code-block\" data-code-lang=\"text\"

but it looks like that is fixed now? I see there is zend_interrupt_function, which is now used to call signal handlers from pcntl. A PHP profiler that uses EG(vm_interrupt) would be really neat.\u003c\/p\u003e\u003c\/blockquote\u003e\n\n\u003cp\u003eYes, zend_interrupt_function is used for timeout\/signal handling now (though I think signal handling came in later, in 7.1). I \u003cem\u003ethink\u003c\/em\u003e it should be possible to reuse it for profiling too. The caveat there is that it seems to not be triggered on every statement but rather in some points like calls, branches, etc. - so profiling might be less granular than e.g. line\/statement based profiler (which would require employing something like EXT_STMT functionality and thus have much worse performance generally). So it depends on how granular we want the profiling to be. If it's only fcall level, then the old zend_execute override should be fine.\u003c\/p\u003e\u003c\/div\u003e\u003c\/span\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"phui-timeline-event-view
