I run musicpd, streaming via icecast with 4-5 clients, on a not crazy fast 1.8 GHz Core Duo (*not* Core 2 Duo :), which is also a desktop system and running a number of development web servers in C++, python, ruby. I've only got a GB of RAM, so I am perennially swapping. With SCHED_4BSD, running a make world would result in the music stopping lots. With SCHED_ULE it never skips or pauses, and, with acceptable waits for processes to get swapped back in, the desktop remains very usable. I don't build world with a reduced priority either. ULE is a very, very good scheduler IMHO :) Now, if only I could stop Firefox leaking insane amounts of memory, I wouldn't even need a RAM upgrade :) Tom [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (FreeBSD) iEYEABECAAYFAkgFwk4ACgkQlcRvFfyds/dSQACdEOz5NIf1LtYn2bTfKIpAU0bn MDkAoIhTB7mgJB/WL8dXtKxr4dMjwhUy =P7+/ -----END PGP SIGNATURE-----
