Solaris can't be recompiled UP AFIK. This whole discussion about UP performance is almost pointless in linux since we have CONFIG_SMP and we can recompile it.
Especially if what you care is the desktop (not the UP server), the only kernel bits that matters for the desktop are the VM, the scheduler and I/O latency and perpahs the clear_page too. the rest is all a matter of the X/kde/qt/glibc-dynamiclinking/opengl/memorybloatwithmultiplelibs/etc.. the kernel core-raw performance in the fast paths doesn't matter much for the desktop, even if the syscall would be twice slower desktop users wouldn't notice much.
