Ironically, tt mode is faster than skas mode when you have a lot of highmem in use. skas mode is slowed down that much. I'm thinking of ways of improving that. The current plan is to make kmap/kunmap do reads and writes instead of mmap/munmap in skas mode. That will exchange I/O for the tlb flushing. We'll see how much difference that makes.
