[Bioperl-l] Excessive CPU use by various Bioperl sites

Robert, 

Not sure why you're seeing that, but the HOWTO (and, AFAIK, the wiki in general) do not use JS, unless there is a specific addition I'm unaware of.  Now, the site wiki was recently 'parasited' for redirects, which may be the culprit, but this is now fixed.  Can you at least retest to see if this persists?

Anyone else know about this?
