Hi Tupp
Ya maybe, in fact i havent that increase of memory / day.
It really growh in a few days but then it keeps stable.
I also assume i turn off bots almost all weeks at least one time, just to be sure all will run perfectly, and that can be the cause, but certanly whith 2 gb of Ram you will be ok.
Only one thing: I have VPS with SSD Drive, that also improve my overall performance.
