Running "varnish" showed a few of the issues with memory, I think it doesn't handle memory mapped files well in the client or some such. It ran Squid passably instead, but varnish is a better reverse proxy. I've used UML, it was fine except for lousy I/O performance in the configuration we had. And it required bespoke kernels etc, so a lot of messing around to get started and to upgrade kernels etc. I think XEN is probably best supported virtualization on Debian. kvm is up and coming. I'm concerned about reliability of virtualization technologies. And as such any that don't offer distinct benefits in this area (i.e. switching hosts when one fails automatically) is likely to drop reliability of performance. Any specific heavy lifting tasks may still show deficiencies of virtualization. Also try and use something you can run out of stock kernels unless you really enjoy compiling your own kernels and the testing that comes with that. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
