Or at > switching to FreeBSD's, which has many more options supported? FreeBSD sort was slower than our sort for a few different cases I tested a couple of years ago. One example I could find for a 1.9GB input file: 13.050u 3.333s 0:16.63 98.4% 0+0k 0+68804io 0pf+0w netbsd sort 68.637u 3.672s 1:16.09 95.0% 0+0k 0+15718io 47394pf+0w freebsd sort (thread disabled) 102.557u 6.053s 0:34.09 318.5% 0+0k 0+15718io 174953pf+0w freebsd sort (32 threads) OpenBSD doesn't have the threading. I'm all for pinching good ideas for options, but would be quite reluctant to do a wholesale switch without a proper performance evaluation first. Cheers, Simon.
