Ready Boost memory stick speed vs real world performance

[Bob]

Just wondering if there is a noticeable difference in performance using
memory sticks of differing read/write speeds. I spent some time reading a
couple of articles recommended in this group on compatibility with Speed
Boost and measurements of actual read/write speeds in different brands of
memory sticks, but no actual real world tests comparing the actual
differences in performance. I would imagine that there is a point where
faster memory does not translate into any real difference in actual
performance and am wondering if it's been shown at what point the speed at
which the memory reads/writes doesn't increase performance.

I tried the lexar 4gig 150x, it was the fastest on the shelf at fry's, I was
disappointed the performance of readyboost, it actually slow thing down.
Everytime the usb memory was accessed the CPU process take a hit and slow
down everything. I would recommended the usage for system with 512mg
memory. My laptop took 5mins to sysnc the pagefile from harddrive to the
stick when plug it in.

My gut feeling is that your USB controller is either under powered
(borrowing CPU power), or that you have a driver issue.

My Gigabyte (NVIDIA chipset) motherboard shows the same until you
install the correct drivers.

huh? That's not what ReadyBoost does...

Readyboost works great on my system.

That doesn't make sense at all. First of all make sure you're running
current MB drivers. Readyboost is good in other memory configurations as
well. I have 2 gigs of ram and run several VPC sessions. When I start
running out of physical memory I pop in my SanDisk USB and my system
performance is greatly improved over trying to run it without Readyboost.

As far as your page file goes.... That has nothing to do with Readyboost.
When you plug in your USB it does not sync the pagefile from your system.
When you us readyboost it should have asked you how much you wanted to
allocate to Readyboost. The file is then created on the USB flash device.
It doesn't sync the OS pagefile.
