Has anyone tested sustainable bandwidth over using
IP emulations lately?  I remember in the past getting
measurements that were close to peak (> 200 MB/s) for
B cards.  However, I just tested mpptest over ch_p4 but
used the myrinet IP interface and I am only getting
60 MB/s.  Is right?  The MTU is set to 9000 and I have
tried several different nodes.

I am using Fedora Core 1 with Linux-2.4.26.  The gm version
is 1.6.5.

thanks,
Craig
