[Winpcap-users] WinPCAP packets capture delay..

[Alimjan Kuramshin]

Hello, Gianluca!

Thanks for reply. Maximum delay, and it's not gone away from test to test, is about 2-5 ms.. within 10000 packets and about ~15 ms maximum
value within 1000000 packets. And, i guess, very important thing, that is delay present in all of the test, doesn't meter how many times i've
run the test. 

Many thanks, bye.
