This shouldn't be a problem unless your fetcher hangs on regex 
processing. This is relatively easy to check - pick up one of the 
remaining longer-running tasks and do a couple of thread dumps, you will 
see what occupies most of the time; if you can hook up a profiler in a 
fast-sampling mode then it's even better ...

True, I don't - I'm using only a combination of prefix/suffix filters. 
Prefix filters give me the domains of interest, and suffix filters give 
me (more or less) mime types I'm interested in. Any other border cases I 
can hardcode in a separate urlfilter, thus avoiding regexes completely.
