OK, it wasn't clear that you were talking about a specialized
circuit delivered from a telco.
BTW, this phrase "the line was dropping to 500Kbs up/down"
implies that there was some protocol synching taking place
that negotiated the speed at that level (like a dsl line).
It would be more accurate to type "my observed throughput was
only 500Kbs up/down."

My reference to the cable was for a situation where we're talking
about a real local area network, where you might have a central
switching fabric and machines distributed perhaps throughout a building
and was meant to apply to the cable run from the main switches to the
openser box.
So, now I don't get your set-up... when you typed "I had to lock-down
the network card to 10mbit full-duplex" and then the bit above about
the MCI technician and the 4Mbit circuit etc. then this sounds like
you have a box running openser that is directly plugged into a
metro-lan-style connection that is hardcoded at the provider end to
10/full.
And yet, when you type "datacenter patch-panel" this implies that
there is a local area network which implies some sort of central
switching fabric and then when I consider "old 10Mbit equipment"
together with the phrase "datacenter" my jaw hits the ground...
Where is your server?

Well yes... that's what I meant.

In a datacenter I have a rack, with a 24 channel patch-panel that takes 24
cables to the meetme room, where the E1s are patched through to the service
providers. 1 of these is patched through to MCI, and 1 to Interoute for the
ethernet connections. MCI provide a 4Mbit burst/10, and Interoute a 10Mbit
burstable to 25Mbit (delivered on ethernet).
In the cabinet each of these go into their own Linux firewall, each with 3
nics. Behind these firewall are the openser servers, mediaproxy servers, and
Cisco AS5400/5350 and Lucent max tnt pstn gateways.
The firewall connected to Interoute autonegotiates its connection just fine.
The openser server behind the MCI firewall seemed extremely sluggish, and
during tests we couldn't get a reliable throughput. It seemed as if the
openser was slowing-down, but in fact it was because the nic of the firewall
was in half duplex. After using ethtool to lock it to 10Mbit/full, everything
worked fine.
I just thought I'd mention that in case it helped anyone having a similar
problem..
And yet, when you type "datacenter
patch-panel" this implies that
there is a local area network
No, just a patch-panel with 24 sockets in the front,
and 24 cables going to
the meetme room, not a switch.

The
datacenter doesn't do any switching/routing, they just provide
point-to-point connections between the rack of the provider, and the rack of
the user. I don't see anything wrong with a service provider using older
10Mbit equipment to provide a 4Mbit line really...
Where is your server?
interxion.com , Brussels.
Hope that cleared up the confusion :o)
