Does Ready Boost use a lot of CPU?

I have a 2 gig flash drive that vista says is usable for Ready Boost and I
have allowed vista to allocate the recommended amount on the drive.
As soon as I plug it in my CPU which was at 5% goes crazy. Jumping from 8
to 50% constantly.
It seems that my performance has actually decreased. Is this possible?
As soon as I unplug the flash drive my CPU settles down to 5%.
Specs:
Microprocessor 2.0 GHz AMD Turionâ„¢ 64 Mobile Processor ML-37 with
PowerNow!â„¢ Technology
Microprocessor Cache 1MB L2 Cache
Memory 2048MB 333MHz DDR System Memory (2 Dimm)
Video Graphics ATI RADEON® XPRESS 200M IGP
Video Memory 128MB DDR (shared)
Hard Drive 120GB (4200RPM) Hard Drive

How are you checking usage? By the Performance Monitor or the CPU "gadget"?

The first time you plug it in (its best just left in) it creates the cache
which bumps up the CPU speed. Certainly for the first 10/15 minutes or so of
having a new ReadyBoost stick the CPU will go up and down as it also runs
alongside SuperFetch

Byron,

Thank you! Good to know. It's been driving me crazy. I searched everywhere
for info about this.
Is there anything else I should know? Will it behave with lots of CPU
activity after every boot?

If you never take that USB drive out, you'll have good boost performance with
it until you take it out again, even across reboots (although shortly after
login after a reboot, it will be working on the cache creation... but it'll
be fine). The CPU usage spike is worth it. I ran RC2 on a not-quite-new (2
years old) low-end (well, by todays standards -- 2.5ghz p4 and 1 gb ram) HP
laptop, and my 1gb flash drive did wonders with readyboost.

Shawn,

All is well with Ready boost but its use causes this error in my event
viewer after resuming from a "sleep" state. Not a big problem, just a
nuisance.
