Take a small subset of your program that would run through the
critical sections and use ?Rprof to see where some of the hot spot
are. How do you know it is not using the CPU? Are you using perfmon
to look what is being used? Are you paging? If you are not paging,
and not doing a lot of I/O, th
This is a very open ended question that depends very heavily on what
you are trying to do and how you are doing it. Often times, the
bottleneck operations that limit speed the most are not necessarily
sped up by adding RAM. They also often require special setup to run
multiple operations/iterations
