We have unit tests, system tests, page tests, the whole thing makes it a system I’m proud to have a small part in. However, the test suite takes 59 minutes to run on my laptop. It runs against a local postgres database loaded with sample data, and I occasionally try various things to see if I can make it run faster. This is about my experiment with tcmalloc, something I’ve been wanting to try for months now and finally got around to doing. The pound load balancer uses tcmalloc, and Domas blogged about using tcmalloc with squid and MySQL a while ago. [...]

We had very similar problems, with CPU spikes on our MySQL server… Queries started taking ages and the replication got waaay behind the master, it just couldn’t keep up.

Using tcmalloc with MySQL really improved things, and the CPU load is now much more even! :)

Its been around for ages, and it very cross-platform, and has been shown to outperform ptmalloc by a huge amount…

COSS is our storage used, on Linux (Ubuntu/Fedora were having the issue).

So what version of squid did you link against TCmalloc, and were you using aufs ? or were you using FreeBSD ?
