EWF RAM Overlay size

Hello

I created a xp image which runs in EWF Ram Reg Mode. I noticed, that there
are different types of EWF Optimization: Optimal Performance / Less Overlay
Space ( & less writes). Does anybody know the behaviour of this different
types?
I made a test by creating and deleting (also from recycle bin) files
(always the same files). As a consequence of this the Overlay Space shouldnt
grow up very much. To improve performance I disabled the items, which are
described in the EWF docs (NTFS time stamps, system restore, defrag...). But
in my test-results the Overlay got bigger and bigger very fast. This is not
very useful, because the computer should be online for a long time period.
Or is there something like a 'Garbage collector' which frees up RAM after a
certain time period?

Hello Andreas,

try to design your system like this:

Used working memory of OS and applikations
+ free space of the used partition *1,5 (factor includes an security
value)
+ working memory for graphic adapter (if it use shared memory)
= your whole working memory

After a while you will see that your overlay doesn't grow anymore.


Regards,
flo
