Re: Recommended swap size for 4GB installed RAM

What would you say is optimal swap size for 4GB of RAM.

Also, can linux swap to flash drives? Is that a dumb idea in light of
the limited number of writes on flash drives?

thanks

It would depend critically on the tasks you intend to run together, and
those that run continuously, but perhaps in wait state (sleeping).

Some give formulae to figure this out, but they do not make sense to me. The
more memory a machine has, the less need for paging. I have 8 GBytes RAM and
none of it has ever been used (I allocated 8 GBytes of swap space).

When I had only 4 GBytes, a few hundred megabytes were used.

But if you are doing serious high resolution graphics or something, perhaps
more swap space would be needed.

On the other hand, if you really need much swap space, you are probably
paging too much and your system response time will be poor. In which case,
what you need is more RAM, not more swap space.
