Greetings,
It's a common misconception that the bottleneck in most systems is the
CPU. I've found that the vast majority of user complaints about 'speed' hav=
e
a lot more to do with I/O than with processor or RAM. Have you considered
getting lower-end CPUs and diverting the savings to higher-RPM hard drives?
A 10,000 RPM drive or an SSD in a system will have a dramatic effect on boo=
t
performance, while a faster CPU will have virtually no impact.
Here are some boot times from systems laying around my desk right now:
Cheap ASUS netbook running the 'lab' image (slow Atom machine, slow drive):
1:12 from end-of-BIOS to login prompt
Dell Latitude 6420 laptop running 'standard' image (fast i7 machine, slow
drive): 0:59
VM running 'standard image' (medium Core 2 machine, fast drive): 0:34
All of these are running Windows 7, which has MUCH better performance than
XP when applying group policies ('applying computer settings') during boot.
Also, I've cut boot times a bit by replacing the built-in Windows 7 defrag
task with a weekly MyDefrag task that performs 'system disk monthly
optimization'.
