Paul Benetis found something interesting on his blog:
After setting it up I started loading it with articles. Everything was gravy until maybe an hour after the initial setup. The blog started to crawl. I mean it was completely unusable.

That in and of itself isn’t terribly unusual, there are a thousand things that can cause a blog to be slow, but check out what Paul found:
I went ahead and activated Akismet (it took about 5 minutes to navigate to the activation page!!!). Right when I pressed the activate button the blog started acting like any WordPress blog should, fast as hell! Thank you Akismet!
