Actually, how does putting the environment on a tmpfs give much of an
advantage over opening the environment with the DB_SYSTEM_MEM flag set?
Taken from http://www.sleepycat.com/docs/ref/env/region.html
2. If the DB_SYSTEM_MEM flag is specified to DB_ENV->open, regions are created
in system memory. When regions are created in system memory, the Berkeley DB
environment may be accessed by both multiple processes and multiple threads
within processes.
I'm having trouble seeing how I could set that in DBCONFIG, though..
I only find reference to it as a flag passed to DBENV->open.
