 one workspace to another takes seconds. when idle the kernel consumes like 4-6 
% cpu as shown by t
op. I have never seen solaris idle cpu usage beyond 1%.

If you are running a debug kernel, you can try setting:

        set kmem_flags = 0

in /etc/system


This change requires a reboot and should help tremendously for the
"feel" in some cases.

However, a software controlled mouse can also be jumpy because of memory
pressure; switching of kmem_flags will ease the memory pressure but may
not solve it.
