[cl-ppcre-devel] slow matching
by Carlos Konstanski 23 Jul '08

23 Jul '08

I was not on the list at the time that Edi posted the message "1.4.0/1 performance" which is why I am posting a new one instead of replying. I am using threaded SBCL 1.0.18 on gentoo amd64. On my platform, matching has slowed to a crawl. It takes 1.5 to 2 seconds to perform the following match: (cl-ppcre:all-matches-as-strings "^\\d\\d\\d\\d-\\d\\d-\\d\\d\\d\\d:\\d\\d:\\d\\d\.0$" <anystring>) I'm sure I could write this regex better. Nevertheless it runs hundreds of times slower than it did previously. I'll test on the same setup with x86 and give a report. Carlos Konstanski

[cl-ppcre-devel] 1.4.0/1 performance
by Edi Weitz 03 Jul '08

03 Jul '08

Hi, The recent 1.4.x release which replaced hash tables with a "charset" implementation by Nikodemus was meant to make scanner creation cheaper while not sacrificing matching performance (ideally increasing it). I have to admit I haven't tested this a lot before releasing it (except for correctness), but there seems to be some evidence that scanners are significantly slower now for some Lisps. I'd be interested in your experiences on different platforms. This change should only affect regular expressions with character classes and it should only make a difference for large values of *REGEX-CHAR-CODE-LIMIT*. If you see significant changes in that area, good or bad, please let me know, including your Lisp and OS. If the majority sees a degradation, I might just revoke this change. Thanks, Edi.
