I'm reading white papers and hearing that to improve Oracle and backup performance, jumbo frames and/or MTU set to 9000. On the server(s) this is easy. However, jumbo frames is not enabled on our switches. The reason (I'm told) is we have too many WAN users. If they were to hit Oracle on a server set to jumbo frames performance would be degraded due to fragmentation. Can someone elaborate on jumbo frames and when or whether they should be used?
I have this problem too.
