We have been having some persistent issues with kojipkgs01 lately. kojipkgs01 is our squid proxy in front of koji builds. It allows users and builders to get fast access to packages. (When it's working). Lately, it's been working fine at first, then in a few days or so it starts getting really slow. Downloads go from 25M/s to 200k/sec and sometimes things even just timeout. Restarting squid seems to fix this... for a few more days. There is never any errors on the box, i/o, load and everything is fine. I looked this morning a bunch at options and adjusted the memory cache down in case we were hitting some kind of issue with memory cache. I'd like +1's for that change, and also to solicit ideas for what we can do to fix this once and for all (if these changes don't do so). diff --git a/roles/kojipkgs/files/squid.conf b/roles/kojipkgs/files/squid.conf index b011143..a0d5312 100644 --- a/roles/kojipkgs/files/squid.conf +++ b/roles/kojipkgs/files/squid.conf @@ -6,8 +6,8 @@ hierarchy_stoplist cgi-bin ? cache_swap_low 98 cache_swap_high 99 -cache_mem 50 GB -maximum_object_size 700 MB +cache_mem 10 GB +maximum_object_size 200 MB minimum_object_size 0 KB cache_replacement_policy heap LFUDA maximum_object_size_in_memory 100 MB
