Apart from using up too much disk space, how much swap space can you allocate before it will degrade performance or cause problems on an x64 OS? What differences are there between the x64 OSes? I'm not talking used swap space, just telling the OS use x much for swap.
I get sick of the problems associated with dynamically changing the swap size, and I don't want to run out. Plus I'm the type of user who has a lot of things open simultaneously even if they are large programs, eg. right now I have 12 chrome windows probably averaging 10 tabs per window, plus my other running programs including firefox.
Edit: Maximums allocated with no performance loss or errors so far
- RAM Multiplier: 4x Unknown OS
- Maximum GB: 128 GB Unknown OS
1I disagree. An OS will need to keep track to remember which part of swap is in use. That will cost some memory. This should not cause problems in most cases, but if you have a low memory host and huge swap then it can degrade performance. (E.g. a 32 MB computers and a few TB of swap). This is why I disagree with your opening sentence "No amount of swap space is too much". Up to 4x main RAM should be fine though, – Hennes – 2014-01-31T06:39:51.813
The memory used for bookkeeping need not be proportional to the amount of swap space, it can be constant with more memory only making possible to keep more of the swap space availability map in memory making searching for free space faster. – Dan D. – 2014-01-31T06:49:45.327
@DanD. "need not be proportional to the amount of swap space" but is it? and on which OSes? – BeowulfNode42 – 2014-01-31T07:19:55.327
@DanD. What OSes have you run with the 4x and which OSes with 128GB? – BeowulfNode42 – 2014-02-02T23:47:07.563
