I'm not convinced its as fast as it should be on 2.6.27.

I'm currently testing 2.6.27.14 hosts on several different pieces of
hardware with a common 2.6.23.17 guest.

Currently the UML guest on my desktop machine which is an 11 year old
300Mhz dual-processor Pentium-II with 256MB of RAM running 2.6.22.14
is giving a rather sound performance drubbing to the identical UML
guest running on a 2.5GHZ dual-quad 5420 with 16GB of RAM running a
32-bit 2.6.27.14.
