Just pondering on SSDs and Swap.

If you have a system with just an SSD then what do you use as swap?

Assuming that you don't (as in most laptops and older desktops) have
the
space for masses of memory?

"Most laptops"? 8G and 16G on the laptops in use here :-)

For some years now I've made sure no system I have anything to do
with
is running into swap.


Nice if you can afford the luxury....

Guess how much RAM gridwatch runs on, and how much swap it has?


How much?

384Mbyte

Think there's a gig of swap.

People often think they need more ram than they actually do.

So next question : is TNP's system running into swap? I'd expect it to
not have to. If it's not, then it seems that TNP can indeed "afford the
luxury" of a system not using its swap.

Oh it runs into swap OK especially if its under attack.

Then I have to fight to shut down the webserver and it can take minutes
to get a login prompt

(I do get irritated by eg database software installs which complain that
your swap file is too small. Yes, it's tiny, but that's not a problem
because the server has 60G of memory...)
