Hi, i just wanted to let you people know that i started a wiki page to
collect info which might be usable for users of 2.6.x who want to
achieve low latency on their system.. content is pretty much lacking
right now and my description of the effects of ingos volountary
preemption patches might be completely off. Maybe you people still want
to take a look and maybe fill with some meat.. Later this info could be
moved to the LAD/LAU site..

P.S.: does anyone know how to make phpwiki use preformatted text?
