I have 3 Win 9x machines (2 Win 95, 1 Win 98). Two have 300 MHz PII
processors, 1 has a 266 MHz PII processor. The slower processor has 192 MB
RAM, while the faster processors have 128 MB RAM. (Don't ask why; it is an
accident of history).
Anyway, I don't see a measureable difference in processing speed (same
data, same wide range of functions) between the slower processor, higher
memory machine, and the higher speed, less memory machines. Since the 266
MHz machine is only nominally slower than the 300 MHz machines, but has 50%
more memory, I would have expected to see some speedup in memory intensive
processes (e.g. bootstrap, monte carlo simulations).
There is clearly a difference between 64MB and 128/192MB, but is there a
next order of magnitude where I might see some significant performance
improvements? 256MB, 384MB, 512MB. Memory is cheap now, but I don't want
to waste money to gain nominal or no improvement.
What performance gains, if any, might I expect if I double the
memory? Triple the memory? Quadruple it?
Thank you.
