No I don't think 3G is nearly enough. We had 8G and I had to bump it because some queries killed the server. Also, in my experience, one of the failure modes specifically on low memory is not clean OOME but rather progressive performance degradation where the memory does not technically get to 0 but management starts taking more time and the server is essentially stuck and unable to serve the regular load.
I am not sure why having more memory leads to longer GC btw - if that memory is unallocated, what GC is doing with it? What the time is spent on?
