This regexp could be improved, possible severely. Now, it makes use of greedy quantifiers, and it is bad for it's performance Unsure, what are you trying to extract here.
^.*[\\^][0-9.-]+\\|[A-Z]+\\|[a-zA-Z0-9.-]+\\|[a-zA-Z0-9._-]+\\|[a-zA-Z0-9]*\\|([a-zA-Z0-9._-]*)[~]*[a-zA-Z0-9._-]*\\|.* -- Pavel Levshin 25.10.2013 15:02, Boylan, James:
Quick Question. Which is more impactful to performance? set $!session = re_extract($msg, '^.*[\\^][0-9.-]+\\|[A-Z]+\\|[a-zA-Z0-9.-]+\\|[a-zA-Z0-9._-]+\\|[a-zA-Z0-9]*\\|([a-zA-Z0-9._-]*)[~]*[a-zA-Z0-9._-]*\\|.*', 0, 1, 'N/A'); or set $!session = field(field(field($msg, 94, 2), 124, 6), 126, 1); I'm going to do some testing, but if I can get a quick response here it could save me some time. I would expect the re_extract function to be, but I'm not familiar with how the code for field works so I can't make that assumption.
