Hi,

We did a test under linux where we put 8 GB of RAM into a server to
see if the database performed better on a disk where the server had a
lot of RAM or where a RAM disk was created and the entire database was
kept on that RAM disk. What we found was that our tests were identical
under each case as it looked like linux was caching as much data as it
could and was in effect moving the database to RAM automatically. I
think the concept of RAM disks and databases completely in RAM may not
pan out like you think it will. We were very surprised at the
results...
