If you are using smaller buffers anyway, maybe the 1/4 restart limit is too low. I'm running closer to 2000 tx buffers, so my restart level would be at around 500 buffers. I did not see any drop in tput in my test case, but rather saw improvement. Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
