Well, I have some rough numbers taken back in 1998, so they are from the
HTML::Parser version from that time.
HTML document size 116,997 bytes
3398 HREFs (plus other tags which weren't of concern to my numbers at the
time)
SPARC Ultra 2, 2x167MHz
One pass through the document with HTML::Parser ~40 seconds
One pass through with home-grown parser ~ 18 seconds
Sorry these numbers aren't more accurate, but we weren't doing serious
benchmarking recording...
Regards,
Christian
