This is mostly idle wanderings than anything useful, but I've just
redirected an application which creates a lot of temporary data to a
tmpfs mount point and I'm happily observing disk bandwidth dwindling
from a sustained many dozens of MB/s to merely hundreds of KB/s, which
is the value the

I can't help you with PCI bandwidth usage(and personally I'd be very
interested in being able to measure that), but I do know that
Nehalem-based Intel Core i7s (and presumably more recent Intel CPUs)
export PMCs for measuring memory bandwidth utilization. The PMCs for
the Core i7 are:

The problem then is how to feed both machines the same inputs, and
compare the outputs. Do we need a third machine to supervise?
Can we have each machine keep an eye on the other, avoiding the
need for a third machine?
A pair would work as long as the only failures are obvious (e.g.
Near the end of vm_pageout_page_stats() there is the following code:
if (m-act_count == 0) {

Hello everybody,
I originally posted this at freebsd-questions and was referred over here.
I recently got a HP t5700 thin client that I wanted to turn into a
firewall using pfSense. For reference, this system uses a Transmeta Crusoe
TM5800 CPU with a VIA chipset that I'm having difficulty
