Depends on what you're doing. I've worked on systems where we had 72gb and 96gb of RAM, and we tuned them within an inch of their lives. But hey, 512k is good

Depends on what you're doing. I've worked on systems where we had 72gb and 96gb of RAM, and we tuned them within an inch of their lives. But hey, 512k is good enough for anyone, Bill Gates once said. edit: If I was doing something memory-intensive or performance-intensive, I wouldn't be on Heroku anyway.
