Oh no, they can be very bad and can choke performance measurably.
They are very subtle too because you will not see them if you are
"close" to the server.  Once your RTT increases then you are more
likely to see this problem, especially if you have a fat pipe (eg
cable, adsl) because you can quickly fill the window and then have to
wait for the acks to trickle back.
