It's been my experience in network testing that unless you are strapped to a serious drive array, you will run into the spindle speed of your hard disk before you flush a 1Gbps link.
I was doing some stress testing of gigabit equipment (Cisco Catalyst 6000 core switches) and we had two machines with Gig-E links copying DVDs to each other simultaneously, and the switch only registered about 250 Mbit/sec. We then maxed the boxes on RAM, created RAMDisks, and setup scripts to copy. That was more data :) - Chris -----Original Message----- From: Wan Tat Chee [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 27, 2003 6:36 PM To: [EMAIL PROTECTED] Subject: GigE performance (was Re: [Freevo-users] Parts for First freevo) This is slightly off topic, but the real-world performance of GigE is nowhere near 1Gbps if you use a hub. I don't have the math in front of me, but I don't think you'd achieve even 50% performance (typical for 10BaseT) over copper-based GigE of reasonable length (more than a few meters). Not sure if a full-duplex link (switched or cross-cabled) would let you achieve close to 1Gbps assuming that your computer can keep up though.
