snoop (solaris) and Network monitor (Windows) can also be used instead of wireshark (or Etheral),
You should measure the disk (read) speed independent of the network components and tape components.
Check [Performance & Tuning Guide P.92 "To measure disk I/O using bpbkar"]
*** Perform bpbkar (disk read only) by Solaris client
bpbkar -nocont -dt 0 -nofileinfo -nokeepalives <PATH> system > /dev/null
*** Perform bpbkar (disk read only) by Windows client
bpbkar32 -nocont <PATH> > nul 2>&1
*** Perform local backup by Media server

We have full jumbo frames support throughout our gig datacenter, end to end.
We have not yet implemented it.
AIX master / media server is 1500MTU & so are wintel boxes, exchange etc.
We get 10MB per storage group / file system volume / stream
It seems that most customers experience this on wintel
I have duplicated the setup using Legato Networker with dedicated hardware & the rates are just the same.
Our AIX boxes can send to the master / media at 40+ per stream
We are looking at non LAN methods to backup large systems in order to meet our restore SLA. Maybe dedupes, staging, SAN snaps. We have a design excercise ongoing.
