Grabit - Newsgroup issue

Hi and firstly thanks for this potentially very good firewall.

One issue I have is when I try to download a message or file from a newsgroup using grabit (or any client).

The speeds are shockingly slow.

I have an 8mb connection and understand line quality, distance from exchange etc. but when I used Outpost my speeds were allways max. With Comodo they are a fifth what they should be.

Grabit has full access rights in settings.

Any help appreciated.

Thanks in advance
