I have problems understanding this. If there are a lot of IP packets
lost, I fail to understand why it is better to leave the resending to

Can anyone explain it?

We use TCP mounts to get past firewalls here at the university , but
have not tried it to increase performance. I do know that it might
help to increase the block size. Did you try this?
