Go to:
Preferences > Advanced > Publish > Spam blacklists (comma-separated)
and remove sbl.spamhaus.org if it is there.
If this does not resolve the problem, read up on Diagnosing Performance Problems.
This FAQ does not apply to:
- Sluggish admin-side performance
- Slow rendering of article list pages
