Re: serious regex performance degradation after upgrade to perl 5.8 from 5.6

You're not benchmarking regex performance. You're benchmarking the time it takes for perl to start up and regex performance. 100 iterations is too few for an accurate count.

Excellent point Anonymous Monk - dmandel would best advised to employ the Benchmark testing framework as suggested by aragorn in this post. I would additionally recommend dmandel to take a look at Benchmarking Your Code by turnstep. `perl -le "print unpack'N', pack'B32', '00000000000000000000001010101111'"`	[reply]
