So it seems that this process (usually a daemon) is still running in bg and eating up more cycles than necessary. Even then performance is extremely slow compared to 4BSD. However in single user mode (with no bg processes), performance seems normal. When I mean slow.. it means being able to read line by line as ipfw rules are being added by a script, or an ls -l output on a large directory. I'm going to compile a UP kernel, and report if it makes a difference. -- "Optimized, readable, on time; Pick any two."=20 FreeBSD 5.1-CURRENT i386=20 12:55AM up 5:36, 1 user, load averages: 0.45, 0.39, 0.34 --=-dIZXigOF1h9Od4GiX+4T Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (FreeBSD) iD8DBQA/Gs5YDAqnLW/+/X8RApjDAJ9R+Y50qKCjlJ79tI3LM7wBpb5EygCg4LJO 4+P18b3IWIIQMpvQ513ksOw= =JL9u -----END PGP SIGNATURE----- --=-dIZXigOF1h9Od4GiX+4T--
