Did you try comparing it to other allocators optimized for multi-threading such as hoard, mtmalloc or ptmalloc?

Tue, 05 Jun 2007 17:46:29 +0000

[...] One of the web apps I work on has a really fantastic test suite. 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. [...]

tcmalloc is awesome! 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! :)

What does tcmalloc give you over the Hoard allocator? Its been around for ages, and it very cross-platform, and has been shown to outperform ptmalloc by a huge amount…

[...] jak większość programistów wie, systemowy (glibcowy) malloc jest delikatnie sprawę ujmując zbyt ogólny. mniej delikatnie – do niczego. sprawdza się przy programach gdzie wydajność nie jest kluczowa. problem jest znany. część projektów pisze własne wersje malloca – przykładem chociażby postgres i jest palloc. jak mi donieśli zaprzyjaźnieni admini google wypuścł, a kolesie od wikipedii przetestowali, nową wersję malloca. ta – napisana przez google’a, nazywa się tcmalloc i jest dużo szybsza. można obejrzeć np. spadek zajętości procesora przez squidy zrekompilowane z tcmalloc’iem – różnica powala. tcmalloc jest całkowicie bezstresowym zastępnikiem do standardowego malloca. można go alko zlinkować przy budowaniu, albo zaladować przy pomocy LD_PRELOAD. polecam przyjrzenie się temu – wygląda mocno obiecująco.

2.6 squid (it has been under performance engineering lately).
COSS is our storage used, on Linux (Ubuntu/Fedora were having the issue).

This is pretty damn interesting. So what version of squid did you link against TCmalloc, and were you using aufs ? or were you using FreeBSD ?

Thanks for using tcmalloc! We’re proud of it too.
