Say we have something like
Process Name Memory Compressed Mem Firefox 2.60 GB 1 GB
What do the figures mean?
- 1GB is compressed and we don't know how much it's compressed by so the app is using somewhere between 1.6 and 2.6 GB but we don't know how much
- 1GB is the amount of memory saved by compression - ie the app is using 2.6 - 1 = 1.6 GB of actual memory
- 1GB is the actual memory being used - ie after taking into account the compression of parts of the 2.6GB, we've been able to save 1.6GB and the process looks like it's only using 1GB
- Something else?
I intuitively thought it was (2) but a friend thought it might be (3). Now I'm thinking it's actually (1)!
