Did anyone get anywhere looking at this issue? -Steve ^ permalink raw reply [flat|nested] 4+ messages in thread

Any further improvement will probably be bounded by the simple synchronous i/o model of usb in Plan 9 (built for comfort, not for speed). ^ permalink raw reply [flat|nested] 4+ messages in thread

More asynchrony => fill more frames with packets. ^ permalink raw reply [flat|nested] 4+ messages in thread
