The cheap answer is that my heavily optimized extract.scm is still > 5x slower than the perl version & is spending the bulk of its time in regexp crap. I had to throw out regexp-substitute/global because it was too slow to get this close. Not to mention that straight regexp stuff is 5x slower in guile than in perl, & >10x slower than in awk. Or did you mean that you wanted to whether or not this was where the regexp time was being lost... -- Harvey J. Stein BFM Financial Research hjstein@bfr.co.il
