[HELP]Reduce RAM

[Varnish]

In older versions vestaCP takes up very little RAM. But now it occupies much more RAM.
1) You can optimize it?
2) Future versions will be solved this problem?
3) What operating system do you recommend?

Are you sure it's a vestaCP problem? There are no other factors? Heavier server load ... At centOS, I have no problems, I notice no higher ram usage.

New installation on Debian 7 32bit Minimal (June 2015 Version): <350MB of RAM
New installation on Debian 7 64bit OVH (November 2015 Version): 1,5GB of RAM
New installation on Debian 7 32bit Minimal (November 2015 Version): >450MB of RAM

I think the higher ram consumption isn't directly connected to vestaCP. In my measurements, I see after the upgrade just a lower ram usage. Probably it has nothing to do with the upgrade but maybe there are other factors. I have also followed closely the development and have seen no adjustments that might result in a higher ram usage.

My measurements on centOS 6.7 64bit (used ram/installed ram) (RAM usage was measured one time per hour.)
10/08/2015 - 20/08/2015 70.1% ram used
10/09/2015 - 20/09/2015 73.6% ram used
10/10/2015 - 20/10/2015 64% ram used
10/11/2015 - 20/11/2015 63.4% ram used
