R help - May 2008 - Heat map on large sample size

Hey,
I'm trying to generate a heat map of 30,000 fragments from probably 5-10
samples. Windows complains about memory shortage. Should I resort to Unix
system?

Also, if I only plot 1000 fragments out, they can finish it rather fast.
5000 would take more than 10 minutes. I don't know what to expect for
30,000...

And on the side note, it seems like R only uses up to 50% of CPU while doing
number crunching. Is there anyway to utilize 100% of CPU for R? I'm using R
2.6.2 on Windows XP SP2, average config.

Thanks.
