Just curious has anyone done comparisons of latency measurements as
one changes the size of a job. That is changing the size of the job

of two of the processes in the job. I am roughly seeing an addition
of 5% to the latency for each node added. This is with the TCP and
Udapl BTLs. I am curious whether other BTLs have similar issues and
if doing some sort of directed polling would help matters?
Is this on Solaris, Linux, or both?
My timings were on Solaris but I am interested in both.
