Comment 3 for bug 1377877

Vivid test machine started performing horribly, this week, after an incremental update -- 80-90% CPU load -- HDD constantly churning -- HDD LED lit-up solid, RAM/SWAP maxed out, et cetera.

Chromium browser would "Aw, Snap!" immediately upon opening. Firefox was usable, but extremely 'laggy'.

Changing the "tracker" settings via dconf-editor had no affect whatsoever.

Purging “tracker” 1.2.2-2ubuntu2 et. al. restored my Vivid test machine to normal operation.

I know this isn't what you need (I've purged “tracker” now), but here's my rig stats, if that helps:
