It finally occured to us to put them into a file-backed memory disk.
Questions:
1. How does the performance of a file-backed memory disk change as it
becomes large?
2. Is there a clever way to make such a file-backed memory disk bigger
after the fact? If I want to expand my 30 GB file to 50 GB, am I
stuck with just making a new one and copying it over?
I've done that by concatenating an empty file of the size I wish to
add on to the end of the existing backing store file, editing the
disk label and then using growfs to expand into the new space.
