How Much Needed

In some forums or mailing list, i often found a question "How much virtual memory is needed on my system?". It's hard to answer this as nowadays, you can easily build a system with 2 GB of RAM (or more) and the old rule to use 2x RAM will not be efficient anymore (then you will have a 4 GB of SWAP partition). If you have some quite time, then i suggest to read this discussion at Slashdot. It's a very very very long discussion about this and take a look at the answers given by other people. At the end of discussion, perhaps you will find better information about this topic.
