Thanks Fajar,
Could you please give me some details regarding how to limit dom0 memory at 
boot time. I'm a bit of newbie in Solaris world :)

Thanks.
If you are running on zfs (zvol ?) zfs needs to be limited. I had the same problem with my 8GB ram home server and it's much better after

set zfs:zfs_arc_max = 0x40000000 # 1024K

when I only use one W2008 server, vm with 2048K ram (xen config) , I also limit dom0 mem by adding to boot options :

dom0_mem=6144

You have toi check that the settings are correct at boot by editing the grub menu option and correct it if applicable. Il the dom0 memory is too limited this can slow everything as well
