Half duplex on 2612

I have a 2612 router (10mb e0). During the sh run, I noticed it is in half duplex.
"interface Ethernet 0/0
ip address 192.168.1.50  255.255.255.0
half-duplex

 When I ran it at full duplex I suffered performance issues.  What would be the cause of the performance issues after running it full duplex. My clients are set to "auto." Perhaps I needed to reload their NIC because it still thinks the router is running at half?

ps: I thought 10mb e0s could only run at half???

Thanks

THe setup is like this

Router (routing between VLANs)
  |
  |             <----------------Trunk Link (int FA0/24)
  |
Switch  (3 VLANs)
  |
  |
  |
Users

So I should hardcode port 24 on the switch to full duplex as well?  I'm assuming full duplex will yield better performance? (slightly faster?)

So if I hardcode the router, I must hardcode the switch and the clients?  Or will the clients auto negotiate (windows clients with 3com nics)
Thanks

Thanks! Got it working. Set the switchport and router e0 to both full duplex.
Should I set the clients to full, or let them auto negotiate?

Quick question though. I have a data drop from my switch (port 1) going to another room. This data drop feeds into a linksys hub. I have 4 pcs plugged into the hub. Is this going to effect whether or not these 4 pcs operate at full or half duplex or not? Or is this unrelated?
thanks!

Unrelated. Hubs only work at half-duplex anyway. If they connect to the hub, they are stuck at half. If it's really a switch, then you should keep the PCs at auto.
thanks everyone
Anytime!
