Do you force 10Mb on your NIC, or do you auto-negotiate that?
Perhaps before you pay a higher fee, your colo centre could allow you to
connect to a 100Mb port (with perhaps some traffic policing) so you, as
a client, could quickly verify if you want to scale up to their next
tier without having to spend these up-front costs on troubleshooting
this back-asswards.

Tell the colo that. Tell them you need to test their next tier of service!

...one more time, don't attempt to throttle your own traffic to
troubleshoot what looks like a throughput bottleneck.
Start with the collocation provider. They should, for free, allow you to
have a testing period with their next service tier. Hopefully, they can
do it without having to swap your Ethernet cable into another device.
If it works during the test, then a small 'migration' and monthly
upgrade fee would be acceptable (if they choose).
