Hi list, I''m looking for some tips to enhance the performance of my system (running on Centos 5.4 Dom0). I modified/add some variables: dom0_max_vcpus, dom0_vcpus_pin and dom0_mem, but I was wondering what else could be tunned... Suggestions? Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

But I already look there. My question was if you (and the rest of the list) have at home/work/etc any special tips for tunning you think are influential to the performance and you think people could use too. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
