Just felt I should post a wrap up on my swap increase journey.
All last week I ran with 4GB real memory and a total of 8GB swap.
I was using all the real memory and pretty much 4GB of swap with poor performance.
What was going on? With Fedora 28 I was running fairly well with 4GB, or was I? Plus I upgraded from a 2 core x120e to a 4 core x140e and I thought things would be better.
So this morning I pulled a 4GB card out of another x140e I have that is currently off.
Free is reporting:
$ free total used free shared buff/cache available Mem: 7416056 3609248 860448 354948 2946360 3158088 Swap: 3419132 0 3419132
and performance is just fine. So I was suffering with only 4GB of real memory. Perhaps F30 needs more than F28 or 4 core is just having more things going and needs more memory.
Anyway, going to have to pop for the $20 for a 4GB card to put into the system that is sitting with no memory....
Thanks for the help on adding a swap file. I have recorded that in my instructions file for any future need.
