I wouldn't say "considerably" slower, but there are some
performance differences.  It's most evident on the
smaller, slower processors, like the 8xx, but we have
taken steps to alleviate that.  The problem is 2.6 is just
bigger with more stuff in it.  You want the new features,
you have to pay for that somewhere.  I think it would
help if the kernel was a little more configurable for
embedded systems.  It seems there is just too much
stuff in a basic kernel that I wish could be stripped out.

You know, this is a "community effort", not "when are you
going to fix it for me" :-)  Use 2.6, measure it using your
application, and submit updates that improve it. Some of
us have already done quite a bit, so do your part, too.

Thanks.
