The ROT have changed over the years. 1:1 is still necessary if you ever want to dump all of a server's memory. If you're not going to care about that, then it"s 2:1 for the first 2GB, then 1:1 after that (roughly), up to about 16GB of swap, depending on the application. If your application programmers haven't read anything in the last few years, they're going to insist on having 2:1, no matter what. (I think there used to be a saying bemoaning people of "few books." I agree, they're a pain.) If they're the ones paying for the disk space, just give it to them. It's probably cheaper than spending a lot of time worrying about it.
