ReadyBoost Tidbit and Survey

[Ben Enfield]

To all,

I have a 4 gig card (with all of it dedicated to readyboost) and the
reliability and performance monitor says that I am only using
2,600,525,288bytes. I was wondering what other's "Bytes cached" maximums
were, the sizes of their cards and the speed rating of the cards (possibly
they are correlated).
You can access the reliability and performance monitor by typing it into the
search thing in the start menu.

Go to "Performance Monitor" on the let navigation paine
Click the Green Plus
Go to "ReadyBoost"
Add "Bytes Cached"
Check the maximum, but make sure you wait for a couple of hours after
Windows boots so it has time to fill the cache. (I don't know if that will
help, but for some reason it makes sense)

I have a P4 3.4GHz with 2 G RAM and a 4G USB with 3.9G set to ReadyBoost. I
have been monitoring over 2 hours and my max is 1,832,452,096 bytes. I have
been hitting it fairly hard, Outlook 2007, Excel 2007, Windows Mail, IE7,
Windows Media Player, Virtual PC with 3 512M guest systems running. I am
wondering if there is a 4G total limit for RAM + ReadyBoost?

I thought that all ReadyBoost does is to cache the pagefile. So when
data is written to the pagefile on disk, it's also written to the
ReadyBoost cache. When data is required from the pagefile, it accesses
the ReadyBoost cache.

Therefore, it seems normal to me that the maximum cache use is equal to
the size of your pagefile.

How big is your pagefile?

Incidentally, I believe that if the size of your ReadyBoost drive is >=
pagefile size, then it'll cache it all immediately. If it's < pagefile
size, then there needs to be some decision made as to which bits are
cached - but you'll probably find Windows will try filling that cache
from the start, and then adjust it as it goes along.
