If you look in src/dev/Ethernet.py, you'll see there's a 'speed' parameter on the EtherLink object that lets you set the simulated bandwidth.
The details of how you set this will vary depending on your config script, but if you're using the makeDualRoot() function from configs/example/fs.py, then after everything is construction you should be able to do something like: root.etherlink.speed = '10Gbps' Steve On Fri, Feb 27, 2015 at 8:03 AM, Ivan Stalev via gem5-users < gem5-users@gem5.org> wrote: > Hi, > > Is there a way to achieve more ethernet bandwidth than 1000mbps when > simulating a client-server model?
