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
interrupt total rate
irq1: atkbd0 233 2
irq14: ata0 85 0
irq16: vgapci0
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?

Here is a patch which I think will address your problem. It is EHCI hardware
related. Different models behave differently. Try this:

I know that certain AMD USB controllers perform less with the new USB stack,
but I've not been able to track down the issue.
Yes, I have AMD platform (motherboard ASUS A8N-VM-CSM)
Can you try another PC having another CPU brand?
Yes, I have already posted the result - 22 Mb/sec, much better

The EHCI is being programmed to interrupt at 125us intervals, but there seems
to be limits other places.

This flash drive works fine on another system (Intel 6300ESB USB 2.0
controller) with FreeBSD-8-current.
May be problem in controller?

Hi please explain what kind of test you have done. It's most likely not
related to USB, but rather the file system.
Maybe you can run the following test on Windows and FreeBSD to compare:
dd if=/dev/da0 of=/dev/null bs=65536
I'm test on FreeBSD7-stable and FreeBSD-current and post results.
