RAMdisks still need a hard disk drive to operate. I am talking here
about entirely diskless configurations.
Well, maybe as I suspected there is no technical explanation why this
design decision has been made.
When I have more time I will run a bechmark to check to which extent
it does make a difference. I mean running the application from RAM and
letting the DBMS know about it instead of letting the OS figure it
out.
