I've got weird load behavior that crops up and this box is only running squid. I am close to what I set my cache_dirs to in terms of size, so wondering if that's it. Just trying to figure out why my server will run at a load of 1 -1.5 and next thing it's up to 5-6, no real increase in traffic. Cache_mem is high, this is a very robust.beefy server. So trying to figure it out. Reverse Proxy config. Squid 2.7STABLE9 Fedora 12 64bit 16gb Mem 4 raid 10 15K sas drives for OS 8 15K sas drives in jbod config.. ---- currently testing with 2 cache_dirs against 2 drives. Very little iowait. Resident memory for the squid process is around 6.4gb, cache_mem set at 4gb. We have tons of small images (3K), so I like to attempt to keep all hot objects in cache. high and low water for the disk were at 85 and 95%, bumped it just to see but made really no difference. My cache dirs are just 5gb each (10gb total), on 150gb disks ya, but I don't really want to have to weed through all of these files looking for an image. Just wondering where I can look and or what type of information would be helpful to see if Squid is in fact causing these spikes, vs something in the OS. Thanks Tory
