-
- None, except that until you install some file as a page or swap file,
- you'd better hope you don't flush the modified page list or your system
- will hang. Fortunately you're supposed to use sypagswpfiles.com, which
- runs early enough in system startup to install the page and swap files
- before flushing the mpl.

- #Is VMS non-paged until a pagefile is installed and present?
-
- All image activation requires paging. All working sets use paging.
- VMS is just as 'paging' with the exception that it can't write any
- modified pages out to pagefile backing until it has a pagefile.
-
- #Is the boot drive pagefile faster or better for the primary system processes
- #that get created before external pagefiles are installed? Just curious...
-
- No different. If you install pagefiles in time (before system hang ;)
- then it really makes little difference where the file is, with the normal
- performance caveats.
