"Does not work well with SMP machines" translates into "does not profit
too much from multiple processors". This is due to the fact that bsmon
is doing most of the work in one single process (except for graph
updating as long as it uses the "rrdtool" command). So you might be
surprised that after adding another CPU has got nearly no effect at
all at bsmon ... This includes the effect of a "virtual" CPU, thus
hyperthreading.

There's currently no real way around this. If performance is a real
problem then it is actually possible to run two or more bsmon processes
each of it only doing part of the work. But this is hard configuration
work (bsmon.cfg) and I cannot predict the effect on performance.
