Do sampled profiling of requests Summary: People have occasionally complained about phabricator being slow. We have the access log to look at to see when slowness happens, but it doesn't tell us much about why it happened. Since it's usually a sporadic issue that's reported, it's hard to reproduce and then profile. This change will allow us to collect sampled profiles so we can look at them when slowness occurs. Test Plan: checking that sampling works correctly: - set rate to 0; do several page loads; check no new entries in table - set rate to 1; check that there's a new row in the table for each page load - set rate to 10; check that some requests write to table and some don't check new ui for samples: - load /xhprof/list/all/, see a list with a lot of samples - load /xhprof/list/sampled/, see only sampled runs - load /xhprof/list/manual/, see only non-sampled runs - load /xhprof/list/my-runs/, se only my manual runs Reviewers: vrana, epriestley Reviewed By: epriestley CC: aran, Korvin Differential Revision: https://secure.phabricator.com/D3458 2012-08-25 00:14:38 +02:00			`<?php`
