Interesting; $someone may do
Hallo,
a size of 'struct vpglocks' is padded to CACHE_LINE_SIZE size in
'sys/vm/vm_page.h'
header file. I work on a 'coldfire' port where CACHE_LINE_SIZE is 16 bytes and
sizeof(struct mtx) is 20 bytes thus size alignment doesn't work.
I solved it somehow, but I like to learn how to solve it i

Just saw the link to a very interesting paper on SMP scalability.
A very good read and highly relevant for our efforts as well. In
certain areas we may already fare better, in others we still have
some work to do.

This paper analyzes the
I have recently acquired a new laptop (to replace the "Frankenlaptop"
I've been using for the last several years).
The new machine is a Dell Precision M4400, so it's pretty recent
technology compared to what I'm used to. :-}
I installed FreeBSD 8.1-R on slice 1, customized it a bit to work in my
