Invest a few extra € and put 8Gigs of ram in that server? Reconfigure the mysql instances to run with just 2GB? Seriously, mysql wants physical ram there for a reason, if that memory is swapped, it would be faster for mysql to just read the blocks from its db files. /Ernst _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
