I stumbled across PR 135178, perhaps there is some relationship with 
these PR's, though the reporter of that PR has not responded in some time.

Fixed by net.inet.tcp.tso: 1 -  0

but why?? found this by trial an error.  setting net.inet.tcp.tso to 0
with pf enabled gives good performance, if i set it to 1, speeds plumet
to below dialup!

There have been problems with Xen and TSO in the past relating to how much
data gets handed off to the hypervisor at once... why this would cause issues
only with PF, I have no idea, though.

 Thirded. My Xen VPS is unusable without this patch (unless I revert back 
 to a non XEN kernel like GENERIC).
