While trying to port amavis, the virusscanner for mail, http://aachalon.de/AMaViS/amavis-0.2.0-pre4.tar.gz ) I noticed it used the file(1) several times for each file, and it took rather long time, causing bb to report red for high CPU-load each time I collected a batch of mail. So I compared it with a Linux box: My 60MHz Pentium, FreeBSD time file /usr/home/leif/vnc-3.3.2r /usr/home/leif/vnc-3.3.2r3_unixsrc.tgz: gzip compressed data, deflated, original filename, last modified: Thu Jan 21 19:23:21 1999 real 0m1.237s user 0m0.758s sys 0m0.394s 133MHz Pentium II, Linux time file vnc-3.3.2r3_unixsrc.tgz vnc-3.3.2r3_unixsrc.tgz: gzip compressed data, deflated, original filename, last modified: Thu Jan 21 19:23:21 1999, os: Unix real 0m0.036s user 0m0.010s sys 0m0.030s While I realise 60MHz is less than 133MHz, a factor 34 in difference of real time seems suspect. The magic file is different, but almost the same size. Why is FreeBSD's file so much slower?
