First, thanks :) Second, as a user, I'd really like if you could manage to implement those ideas before 7.0, and here's why: - The standard for new servers here is 4 cores (in various socket arrangements), and we're not at all high-tech. This is likely to go up. - If you include hyperthreading, even all *desktops* are SMPs! In short, even including desktops, I haven't installed a UP kernel in about a year.= - It's too long to wait for 8.0 for something as important as this. As far as I can see, 7.0 will be one of the "break as many things as you need" releases (in the "good" sense, of course), so why not go for it. Judging from past releases, "even" releases (4.x, 6.x) have been the ones people trusted the most, so if you do get a glitch in 7.0 it won't be as bad :) (of course, you can fix it in 7.1 :) ) Maybe you could borrow the 8CPU machine used for MySQL / filedesc tuning jeffr and others have been using (of course, once they've finished...)? --------------enigA1A6D9267EEBBABC55DEB589 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGC/y8ldnAQVacBcgRAvxiAJ49H3y7Vnlj7ysYJXAsnbrkbgiRdgCfdhhh h0XhPbsT6Mpg7RPVYUH+Xgg= =40K8 -----END PGP SIGNATURE----- --------------enigA1A6D9267EEBBABC55DEB589--
