Please don't do this. This list survives because people willingly read it -
publically doubting other people, who you have no idea about, makes this
list much less useful or welcoming.

Other people, faced with the same trade-offs that any of us face, will make
different choices.

If you want to know about how and why someone uses a Raspberry Pi for a
desktop, ask a question - ask 6! But, please, consider that you are
broadcasting your judgement to a whole list, and that other people may take
that as hostile and simply go somewhere else.

Thanks.

Re: [GTALUG] War Story: adding RAM to a laptop can increase the speed

On the swap usage:

There's a parameter (swappiness, on /proc/sys/vm/swappiness or vm.swappiness
on /etc/sysctl.conf) that tells the kernel how aggressively to swap. A
value of 100 will swap as much as possible until the swap file is full,
while 0 will never ever swap, even if there's space and OOP killer started
gunning processes down because of lack of memory. That changed some kernel
versions ago, before the change a 0 would only swap when memory was
exhausted, and now a 0 means never ever swap no matter what. I was left
trying to figure out why OOP was killing processes when the swap file was
empty.

On virtual servers I usually keep swappiness at 1, so it won't swap unless
there's real need, and on desktops I keep at 85 to free up memory for the
file cache. On a RasPi with sdcard storage, I would keep it close to 10,
because it's better on the SD to read than to write...
