Ext4 is a nice fast journalling file system, but I don't know if it's faster than Ext2, which is older and simpler but doesn't have the journalling. If you do need to format it, experiment and see which gives you better performance.

Ok, a bit of poking around suggests you do need to format it when you create it and before you try to mount it.

I did read that Ext2 is faster than Ext4 with journaling enabled but Ext4 is faster with it disabled. (no idea how to disable it)

I got it unmounted.
I can't figure out how to format it. Google is bearing no fruits.

Thanks, D_A!

Pretty much all I've done is:
mkdir -p /tmp/MC
/tmp/MC chmod 777
sudo mount -t tmpfs -o size=200M tmpfs /tmp/MC
umount /tmp/MC
