Re: NONMEM memory vs. run time

The increase in memory consumption doesn't impact runtime positively or
negatively, unless of course your system doesn't have enough physical
memory to accommodate the increase. NONMEM's memory footprint is
directly related to the buffer values in the SIZES file, as you increase
the values the memory footprint increases to accommodate.

In the end processor speed is really the only thing that positively or
negatively effects NONMEM runtime.
