Community Bot 1. Caleb Caleb I usually have swap as a partition at the beginning of the drive. I personally don't really care about the last few percentage points of swap performance enough to take the extra complexity of a separate partition. If my server starts seriously swapping, I have a problem anyway. The swap space is more of a last-resort safety net in case some process starts gobbling up memory.

That's fine, you're welcome to use a file. I find partitions quite easy to manage but I see your reasoning. You just asked what the convention was and that's pretty much the default scenario. I don't care about performance, since I almost don't use swap any more.

Maybe its main use today is for laptop hibernation, and obviously as "safety net". Show 2 more comments. Just to add my 2 cents to Malte's and Caleb's answers, and also to the excelent reference by Paul: Using swap partitions instead of swapfiles was mentioned often.

However, using a swap file makes it easier to control the swap size without repartitioning a volume. Start with a value of 10 and increase if it necessary.
