Bit of a strange one.
I have a SQL2008 R2 server running under 2008 r2, the server has been in a test environment on a 100Mb switch and working fine while testing. I moved it to a production 1 GB switch with 3 other devices sharing that switch and now the data transfer performance has been reduced, users accessing data on this device have noticed a lot of slowing
The switch is good as are the other units plugged into it, the NIC shows a 1 GB Connection, the switch port shows a 1GB Link, the No errors or bottlenecks are present on this switch.
I cannot understand how moving from slower link to a faster one can cause this issue.
No other servers on the switch as having issues
