The numbers for the 2900 seem right from my experience, but your 410 and 520are both off (more so the 410) for my experiences.

I had a 2950 and what you got on the 2900 is about what I got from the 2950 also.

I get more like 50 to 60 on my 520's vs your 35 to 40.

And like I said before, I get 30 to 35 on my 410's (I said 30 to 40 before but I checked and verified speeds).

Any thoughts?
I gotta tell ya, I am puzzled here. Your speed differences on the 520 is easily accountable to hard drive speeds, switches, routers, memory, etc etc etc. But the speed difference on the 410 is not. Something is just not right there.

It almost looks like you are getting 100baseT instead of Gb (10 to 12 is normal max for 100baseT). That would have made me think cable, but you said you tried other cables.

There is no special setting I use or anything,so as I said, I am puzzled by your 410 speed. I only have a couple ideas ATM.

1) Some switches will automatically slow everything down on them if one of the devices connected is 10baseT or 100baseT. Can you try coming off a diferent switch?

2) There is a setting in the network setup of GOS to set Gb, 100baseT, half duplex, full duplex etc. The default is Auto Select if I remember right. Maybe yours has been set to 100baseT or half duplex? Try force setting Gb and full duplex and see what happens.


That's about all I got other than your numbers are very slow compared to my snap 410's. The 410 is no speed demon, but every 410 I have used/tested (about 7 or 8 of them) have all been faster than your 410 test numbers and inline with the 30 to 35 I told you. Something aint right!

Anyone else (an IT guy/gal maybe) got any suggestions?
