I can — Nemo was referencing some dialog we had while I was trying to figure out performance issues on my farm.
You can see the whole dialog, with graphs, here:

Actually, after rereading that Talk page I'll just leave it at the link. All the gruesome details are there. :-)
TL:DR; Using this stopforumspam method caused me 4-5x slowdown in performance. Jamie Thingelstad jamie@thingelstad.com mobile: 612-810-3699 find me on AIM Twitter Facebook LinkedIn

Al, the problem with stop forum spam is not memory but rather the CPU usage and lag it creates, for an apparently limited amount of spam blocked (at least on small wikis) https://www.mediawiki.org/wiki/Manual_talk:Combating_spam#CPU_usage.3B_IP_blacklists
Hi Nemo. You didn't say why you would not recommend that approach. Can you elaborate?
