Thanks for your help. I take it you let the kernel manage as much as possible.
But I really want to know how I can improve performance in a multi-cpu, multi-core processor systems running multiple cms-websites in a virtual hosting configuration outside the scope of the kernel. For example, a specific RAID configuration that will make it easier for varnish. Or do I leave it all up to the kernel. Is FreeBSD and Linux2.6 equally capable with respect to varnish?

The kernels I know of can be described as distinctively reluctant to write things out. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ varnish-misc mailing list [email protected] http://projects.linpro.no/mailman/listinfo/varnish-misc
