What does 'netstat -m' say? Is there any reason you explicitely set maxusers instead of letting the kernel auto-tune the setting? I would watch your mbuf usage and when you find your average and peak usage, configure your mbuf allocation at boot and see if that helps. I'd also consider letting FreeBSD auto-tune your MAXUSERS. -- Benjamin Krueger SysAdmin, CarDomain Network 92 Toyota Turbo MR2 78 Datsun B-210 91 freakin Geo Prizm _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[EMAIL PROTECTED]"
