Did you try it with perl 5.10 or newer? (sorry, don't have one here available to test it).

Anyway, you could join just 1000 probes into one regex, and repeat the process until all probes are tested against. That's certainly much faster than single runs.

Update: I thougt a bit more about it, and got the following idea: if you have many probes, and use a fixed number of probes per regex, you can try to sort the probes before building the buckets. That way you can play to the strengths of the re engine and its trie optimization.
