hi,
we have migrated our network to cisco standard with 2 6500*Core layer and 2*6500 Campus layer and 2 * 6500 Datacenter layer with IOS version 12.2(18)SXF15a.
we are facing a slowness on the new network where there is no packet drop so could you please advice,

Hi:
Congratulations on setting up your new network.
Latency can be caused by several different things: degraded connections, mismatched speed and duplex settings, some other misconfiguration, overutilization, oversubscription, faulty hardware, application-layer and databse issues that are divorced from the network, etc.
It may be easier to help you if you focused on one flow that is slow. Examine the traffic path device by device and interface by interface and look for any red flags.

hi,
is there any possible to increase the MTU size to 65535 in FWSM interface.

You'll need to further clarify "standard". 6500 hardware has lots and lots of permutations with large deltas in performance. You also need to clarify topology, since with 6500s, performance can be restricted more by links between 6500 rather than the 6500s themselves.
