OK, so after the latest update, I've currently removed all the non-essential (read: non-admin-critical) plugins except hlstats, because the servers were hanging with 100% cpu usage. Since I've done this, I still see 100% usage spikes but the server no longer hangs, and they've been up for about a day (whereas last night there were 4-5 crashes in a 2 hour period). I'll soon begin to start restoring plugins (starting with admin stuff) to see if I can find the culprit. What I'd like to know is: Has anyone noticed improved performance since the great plugin purge last night? If it's noteworthy, it means one or more plugins may be considered for removal if the performance hit is too great.
