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. }-- End of excerpt from "Rafael J.
