We are hosting cs servers. after upgrading glibc 2.2 to 2.3 we have a big performance decrase (top and rcon stats says that). It's between 20% and 50%. Downgrading glibc to 2.2 didn 't work, because 2.3 was still installed. the hlds detects the installed versions and uses the 2.3. So we have formatet and reinstalled Debain with glib 2.2.
Perhaps this affect only CS, but I don 't think so. ----- Original Message ----- From: "Michael McKoy" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, October 06, 2004 4:08 PM Subject: [hlds_linux] Performance tweaks for NS? > I know this isn't really a list for NS, but there's nothing really I can > tweak in Natural Selection, so I figure the more technically minded folks > here can help out better. > > Is it possible at all to run NS with a decent number of slots under Linux? > > My machine is a Dual 2.4ghz Xeon, with 1024megs of RAM, running Debian > Testing (Sarge).
