I was wondering if anyone has any training resources on troubleshooting SMB performance with Wireshark?

I have a situation where the same user from the same workstation accesses the same file on two different NAS devices, and sees much worse performance on one.  I took a look at the trace and see some differences, specifically in the size of the READ ANDX buffers, where one uses a 16K buffer and the other uses a 64K buffer, but I dont see where those sizes are negotiated with the NAS device.

Any help would be appreciated.

Thanks,
Adam
