You might want to run lockstat(1M)
to see if the driver routines are implicated as a problem.
If the driver is not a problem, then you might want to try
CPU binding with
dladm set-linkprop -p cpus=0,1,...,24 <link>
There may be other things to try here.
Also, which OpenSolaris build are you running? In general,
running the latest build is recommended for performance work.

p.s. crossbow-discuss and/or network-discuss is more appropriate
for these questions.
