Re: [Python-Dev] bigmemtests for really big memory too slow

For the record, I've disabled automatic builds on the bigmem buildbot until things get sorted out a bit (no need to eat huge amounts of RAM and eight hours of CPU each time a commit is pushed, only to have the process killed :-)). It's still possible to run custom builds, of course. Regards Anto

[Python-Dev] bigmemtests for really big memory too slow

2011-09-06 Thread martin
I benchmarked some of the bigmemtests when run with -M 80G. They run really slow, because they try to use all available memory, and then take a lot of time processing it. Here are some runtimes: test_capitalize (test.test_bigmem.StrTest) ... ok (420.490846s) test_center (test.test_bigmem.StrTest)
