I agree, swap never hurts. I have a 4GB (planning for 8GB) RAM server my self, I configured it with 8GB. In your case I would go for 4GB swap (assuming that disk space is not an issue) > In reality if you are swapping that much in and out, your server > performance will be quite severely effected. Correct, but in that situation the alternative to have swap available, would be that the application would hit a memory-shortage and crash with core dump > In addition, some hibernation schemes can use swap partition.
