Yes, this is true. That file is inside /tmp normally (i.e. on your disk) an=
is deleted (so only ls /proc/<umlpid>/fd or lsof can show it). But if you d=
then the file will go onto /dev/shm, which is a RAM-based filesystem (i.e. =
file, actually, is on RAM). This will make it a lot faster. Also, remember=
using the skas patch on the host for speed.
