Re: 512MB ram minimum memory requirement
I'm guessing you have more than 4 GB in your machine. Run on a device that only has 4 GB and it won't cache so much. Run memory-heavy stuff on a machine with 4 and it will quickly evict down to make room. It really can run in 4 GB. It can even run in 2 GB without becoming unusable, though it will get slower.
