Thanks for enlighten me. I've a separate backup server (read only slave), where I can do this. So I'll try to get money from the FC for more RAM to make the test in a ramdisk ^^
You may not need to expand the physical RAM. Most Linux systems these days have a tmpfs mounted on /tmp or on something like /dev/shm - this is a 'virtual ramdisk' which will use RAM and swapspace as appropriate. Its size is fixed at mount time, but can be configured to be larger than the physical RAM if you have enough swapspace to support it. Even when extended into swap, I would expect this to be faster than a normal filesystem as it does not have to take precautions to recover after a crash.
