There's a new version of XHGui (well, a few months old) and it's fabulous! It's got a few new dependencies though so I thought I'd write down how I set up my version, in case it's helpful to anyone else (and so I feel like a pro next time I have to do this!). If you're not familiar with XHGui it's a fabulously easy and friendly way to profile your application; to understand which method calls in a page take the time and how many times they are made, so you can improve the performance of your application. All these instructions are for my 32-bit Ubuntu 12.10 system, hopefully they will work for you or you'll be able to adapt them as appropriate.
XHGui needs version numbers or fluffy animal names, because this is a really major release and quite different to what went before in both technology and in looks. In particular, it now uses MongoDB. If you're not familiar with MongoDB, it's a super-friendly NoSQL database that makes a really handy backend for this kind of unstructured data - because every run of every page will look different. Therefore you will need:
- MongoDB itself
- The pecl extension for mongo
- The xhprof pecl extension (
