Ask HN: How much RAM do you have? Think you need more?

It depends on my system. Both my work MacBook Pro and personal MacBook Air have 8GB of RAM. There have been times where I've been 10GB in to swap, and the performance of the system makes me think I'm actively paging.

However, for most cases on my work/personal laptop the 8GB of RAM is plenty.

On my desktop PC, however, I have 12GB of RAM. I use this primarily for gaming, and I have definitely used 8+ GB on this box. The one time, admittedly, Windows Update was using about 9GB of RAM for no reason. But I have had games get up above 3GB in usage.

Also, are you sure your RAM is unavailable and not just used for disk cache or something?

How do I check if my RAM is being used as disk cache? Is that known as "swap"? I'm using the FreeMemory app which tells me that 371 MB is free right now.

I have a 120 GB SSD with 8 GB free.

Macs are based on BSD and such wouldn't use paging as Windows does, only swapping in case if you are reaching 100% of memory.
