And what are the benefits of using it?

zRAM is intended for using in those machines with 2gb or less of RAM, actually you'd get better results and/or see any performance improvement with 1gb of RAM. If you have more than 2gb of RAM it doesn't worth the time since you won't see much of a difference regarding performance, in fact, and according to what I've read,  you'd probably see a decrease of it.
Hope this helps!

Oh I see, I have 4GB on this laptop. So, using it will have no any effect?

hi [member=6081]then00b[/member]
My pc has 4gb of RAM too, when I first found the zRAM feature in Lite Tweaks tool in LL I also wondered whether to use it or not, after doing some reading about it I learned that apparently in my case as in yours with 4gb of RAM  zRAM would make not difference if any at all. However, you could try and see how it goes, it's completely safe to use it so you shouldn't be getting any side effects from doing it, so I guess it's up to you. I haven't use it since I found LL pretty fast and quite responsive. I did activate preload, The benefit is that preloaded applications start more quickly because reading from the RAM is always quicker than from the hard drive. From the wikipedia: "preload is a free Linux program which runs as a daemon to record statistics about usage of files by more frequently-used programs. This information is then used to keep these files preloaded into memory. This results in faster application startup times as less data needs to be fetched from disk. preload is often paired with prelink." Also, you might want to read this article which I find particularly helpful when it comes to undestand that Linux is fast, however you can tweak here and there in order to get the responsiveness you're looking for.
Hope this helps!
