I’ve been banging my head trying to figure out why Squirrelmail is dog-slow retrieving headers from my cyrus imap server on large mail folders. Squirrelmail 1.15 has been hard-masked for a WHILE, gentoo only likes 1.4. I un-hard-masked it (add it to package.unmask AND package.keywords), and it looks rough, but GREAT… FAST! Finally apparently using squatter indexes and/or imap SORT… javascript/ajaxy… will keep tweaking it…
I turned on mod_deflate, but I clobbered SSI, breaking boxcarkid.com.
Config files that still need tweaking:
/home/m/config/apache2/machine_globals.conf
/home/m/config/apache2/virtualhosts/boxcarkid.confAlso upgraded my StartCom certificate, pretty easy! Thanks guys!
After bumping up 60+ packages (probably about half or a third the total), apache started spawning several processes, each taking 10-15% CPU, until my poor little server box was kswapd’ing its little guts out. It was heartwrenching seeing that red drive light on constantly. Poor little thing.
I did an emerge world and rebooted, and this baby is absolutely humming now. load average 0.00 :>
UPDATE: eventually Apache is still hogging things. Looks like gentoo changed the config settings for the Apache memory manager (MPM). There are several choices, looks like I want the “worker” variant. To get it, add APACHE_MPMS=”worker” to [/etc/conf.d/apache2], and update httpd.conf settings to specify performance settings. The defaults are here: [/etc/apache2/modules.d/00_mpm.conf]. I am attempting to adjust them to optimal values in my [machine_globals.conf] file.
The gory details follow. Sure it’s a lot of change, but once again, gentoo is the ultimate power tool. (continued…)
Git caused (among other things) python 2.4-2.5 update. python-updater caused a bunch more updates (including cyrus! AAAA!! Hates it bagginses!). After the dust settled, an emerge-world still wants 60+ more packages. Not now.
Nothing can touch gentoo when it comes to keeping an up-to-date linux system. It has the tools (emerge, dispatch-conf, elogviewer, etc.) to tell you what has changed since yesterday, get the changes, and integrate them into your system. linux is a crazy-assed pile of mismanaged bits that are freshly broken in a dozen ways every single day. Anybody that runs a linux system will…
- spend a not-insignificant amount of time keeping their system running; and…
- tell you they don’t.
It’s part of the whole cocky “look what I can do” competitiveness built into every geek. Go ahead, now it’s time for you to lie to me and tell me otherwise. 😛
My current strategy for staying on the back of the bucking linux bronco… (continued…)
