Wikiepdia also says the following; Using zram also results in significantly reduced I/O for Linux systems that require swapping. Is there any system that does not swapping,I wonder...? Apparently, mine. My desktop has 8GB of RAM, and today I noticed (thanks to this thread) that I have been running without any swap. This turned out to be simply because I forgot to configure one when I chose the disk partitioning when installing 15.5. Looking at /etc/fstab on my 15.4 and 15.3 installations shows that I forgot there as well, so it appears that I've been running without swap for at least several years now, and never noticed. Which pretty much proves that I haven't needed it. Which is just as well, since I don't have an SSD. -- Bob Rogers http://www.rgrjr.com/
