Hi everyone,

I'm at a new job/network where I have started to become aware of some
odd-ball performance issues. We have a 3rd-party managed VoIP solution
with Cisco Catalyst 2950 switches, for which I have absolutely no
access or control over our internal switching and routing equipment -
except for our perimeter firewall.

For the majority of the desktops, their workstations/laptops are
daisy-chained through Polycom IP 501 phones to the switches. A few of
us, like myself, use two data ports (one for phone, one for our
workstation.)

What lead up to this aside, here is the throughput I am seeing ala
RoboCopy while copying XP SP3 (316.43 MB) as a test subject:

Via direct connection: Speed=131.192 MB/min, in 2:24m (meh)

Via phone-chained: Speed=36.764 MB/min, in 8:36m (asolutely horrible)

Via D-Link DGS-2205 switch: Speed=451.726, in 0:42m (WTH ?!)

I'm currently stymied, and our telco provider isn't able to make heads
or tails of the issue. Everything is hard-coded for 100 Mbps /
Full-Duplex.

Any ideas? TIA!
