S4128F-ON switch very slow after firmware upgrade

I have a S4128F-ON switch for which the firmware was upgraded to the latest version. After the upgrade the switch has become very slow and passing data at the rate of ~1.4Mbits/second as reported by iperf. When I bypass the switch and directly connect the servers, the speed is 9.41Gbits/sec as expected for a 10G connection. I think it is a configuration problem. Can anyone help?
