Hi
I use a C3750 as my core switch where I have configured all the vlans for my office. We have a 100 Mbps link for Internet but I notice that the speed is only nearly half from user side. The 100 Mbps link is connected to a firewall to which the switch is connected. In order to make sure this is not an ISP issue, I connected a laptop directly to the firewall and got a speed more than 90 Mbps. So it's definitely not an ISP issue. Attached is the configuration of my switch. I'm not able to find out where the configuration is wrong. Any assistance would be appreciated.

Hello,
I wonder if your switch CPU and/or memory are maxed out. Can you post the output of:
sh processes cpu sorted | exclude 0.00
sh processes memory sorted

can you also post
sh switch detail
sh switch stack-ring speed
Have you tried:
changing to another port
swapping cabling
hardcoding speed:duplex settings
