I saw that also. Even though this is my wife's computer, I will have
to install 64bit also. The funny part was I paid 700 bucks US dollars
for this acer 5000 series laptop, but the first one was broken which
had an ML-30 @1024 Kb cache, 1.6 Ghz) processor. The store gave me the
next model up which had the ML-32 (512 Kb cache, 1.8 Ghz) for the same
price. Looked like a great deal. Now I wonder with those benchmarks. I
will install 64 bit debian this weekend and get back to this list. I
did turn off powernow before running the tests.
For the record it is plenty fast for what my wife is doing (reading
e-mail and the newspaper). Heck it never goes above the lowest cpu
speed with powernow turned on. Now I wonder if a celery-M laptop
would have been good enough ;-)
Later,
Alan
