Greets, gentoo-users,
as I ordered myself an upgrade from 4 to 8 gigs of RAM for my main
workstation, just because it's rather cheap now and I have good use for
the "old" 4 gigs I wonder what to do with those shiny new additional 4 gigs.
OK, linux uses it for IO-caching, yep ...
I have some ram-disk already for compiling stuff (portage-stuff) and I
can think of increasing app-caches like operas own ram-cache to make use
of the memory.
I will give my virtual machines more RAM to improve their performance,
yes, this is maybe the main reason for me to upgrade RAM.
But are there any other things I might forget?
Are there any creative non-ricer ways to really make use of it?
I would like to hear your opinion on this, I am quite sure the
gentoo-community knows one trick or the other ;-)
One thing I did after my RAM upgrade was to put:
vm.swappiness = 30
in /etc/sysctl.conf to make the kernel use less swap. (The default
swappiness is 60.) Don't use values lower than 20 though, and better
don't disable swap completely; it's marginal, but complete absence of
swap can hurt performance even with plenty of RAM.
