I have a PXE booted NFS mounted frontend where the boot files are on an SSD, it's shared with mysql and the master backend system files but it's still very quick. I seem to need to manually trim the drive when it slows a little but then it's seriously quick.
I do have IR lag but if I plug in a keyboard it's instant.
