Questions about editing build.prop because of ram management

Hey all,

I'm really starting to get tired of the terrible ram management on the s6. A few months ago I read about editing build . prop. So, I'm planning on doing this, but I've got a few questions first:

-is it still effective after the 5.1.1 update?
-is there a better "fix"?

Also, I've read somewhere that changing dha to fha has a better result. Can anyone confirm this and explain how to do this?

Thanks guys!

Best Memory Management

What ROM for XT1021 has the best memory management, I'm currently using cm12.1 but can't install any more apps because of insufficient space, I have a 32gb SD card so I can put apps on there if its possible with out partitions

What is the current state of RAM management on the S6?

Hey, I'm considering buy a S6 or an S6 edge but one of the things I'm worried about is the problems with RAM. I've read a lot about problems with RAM management on the S6 with it not able to keep apps running in the background. I can foresee this being very annoying. From what I've read on these forums, I know that people started editing DHA/FHA values and that custom ROMs seem to have helped a lot.

I did however read some recent posts which said that these fixes didn't work and the phones slowed down after a while and still had bad multitasking. I wasn't able to find a place where all the information about RAM fixes was collated so I was wondering if someone could point me in the right direction or tell me that with modding the S6, does the multitasking and ram management become usable? Or is there still significant problems with how the memory is handled?
