A service I manage relies on a third party which still doesn’t provide HTTPS. Their endpoint sometimes shows excessive latency as well (>700ms TTFB). Unfortunately, this service isn’t trivial to replace (aviation charts), and building our own alternative is out of the question at the moment.

I am a big fan of Blackfire, the PHP profiler from Sensio Labs. It is very easy to install and comes with a handy GUI. In the past, tooling such as XDebug + CacheGrind was so tedious that we usually kept profilers for larger projects with critical performance implications.
