My desktop (gig card) is connnected to a 2970 which is fibered to a 3560G. I only get about 10% of a gig connection. I tested a couple of Dell 2850s within the 3560G switch (single connections right now) itself and I get 30% of a gig. Is this normal and where can I troubleshoot if not? I used Racoon's speed test as well as transferring a single 500 MB file between the Dell 2850s.
