Nope, nothing except a vague (and unreliable) memory of reading somewhere there was no improvement, so it wasn't pursued further. Luigi Rizzo posted an interesting comment. The lack of results puzzled me at the time since I read Linux supposedly got decent improvements at the beginning of their 2.6 branch. Here's some links (admittedly, Googled as I don't have my own from that time): - http://linux.inet.hr/files/ols2005/seelam-reprint.pdf - http://kerneltrap.org/node/580 - http://www.redhat.com/magazine/008jun05/features/schedulers/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFnrGLldnAQVacBcgRAsbIAJ4zD3xxbvohsiiKW0ujPzAw6QxAYACg2KjK +5YCoi79/4ajeHBQzmJ792g= =F0Tl -----END PGP SIGNATURE-----
