I think the reduced performance can be explained by a clamp on the

someone has an explanation for this?
The EHCI is being programmed to interrupt at 125us
Repeat the same test using FreeBSD -current.
a) On the machine where it is slow.
vmstat -i ; sleep 1 ; vmstat -i

Hi,
Do we have any knobs in FreeBSD to reduce the interrupt latency? I am
currently seeing performance differences between 8.x and 7.x. Anyone have any
ideas?

Hi,
I have started a page to track USB tasks, please update with any items
and feel free to work on any.
Any discussion about the items should happen on the usb@ mailing list.
