[gentoo-user] how to use RAM

[gentoo-user] how to use RAM

[Stefan G. Weichinger]

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 ;-)

Thanks a lot, Stefan

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.

That was one of my thoughts, yes.
Did that already when I got 4 gigs (and 64bit) ... ;-)

Thanks anyway, Stefan

Hi,

you could regularly measure your disk speed by coping huge amounts of 
data to a second ram-disk, and back. Then you have a good knowledge of 
read and write speed of your hdd :-)

I often use the ram disk for creating iso images before burning them to 
dvd/cd. This is a lot faster than doing this on an hdd.

Just make sure the total amount of data is significantly larger than the 
amount of RAM, to negate the effect of in-RAM caching. A CD .iso for example 
can easily be cached in RAM as well as have the copy too. The write to hdd 
will be almost instant the second time

Why not use hdparm -Tt to test the speed of the drives?  It works pretty
good here.

Good idea. Will try that now as I got my 8 gigs already ...

Non-ricer? Well... this sorta breaks that category.

There's a rather handy tool[1] already in the stage3, I've used it
alongside bootchart to force-load everything needed into ram during
boot, before it's needed, so execution gets held up by i/o just a
little less. Actually shaved a few seconds off of my desktop's bootup
once upon a time (3.0 GHz core 2 duo on 4GB of ram, which had
excessive eyecandy while remaining fairly lightweight). The second use
I put it through, and this one just a little more long-term useful,
was preloading my wm, most of my home directory (primarily all the
config files), aterm, firefox, a few other common tools I use, and the
libraries they were using on my system while logging in. All of my
applications were starting in no time at all. The catch... I took the
brute force approach, rather than using an add-on tool to
automagically choose what to prefetch for me. There are also setting
in the bootscripts that, if you're not already using them, will make
use of at least a little, using tmpfs here and there, and also just
putting /tmp and /var/tmp onto tmpfs (outside of building things like
open office, this tends to work well). Oh, and if you really do want
to use up all that ram.... build openoffice in tmpfs... if it could
use all 8GB for files only, it might actually work out, I know it
kills off when you only have part of 4GB to feed it.

I use sys-apps/preload ... is this comparable?

I don't need to speed up boot-times as I use suspend-to-ram on my main
workstation as well, so I don't care much about booting ...

Thanks anyway for sharing! Stefan

Yep! sys-apps/preload goes a long way to automate what I did with
busybox's readahead tool, and I'm about 99% certain they both make the
same system call to do the work anyways... it's all a matter of how &
where they get their list of *what* to fetch... I, as I said, took the
brute force approach and made my list by hand. ;-)

Ok, so it seems to me that I will just stay with sys-apps/preload and
avoid my own "brute force approach" ;-)

I don't have any particular issues, the box is rather fast and smooth so
far ... and remember my non-ricer-approach ;-)

As I see I am not even able to use much RAM with several (vmware-)VMs
running, so the 8 gigs will maybe stay some number to impress *some*
people with (until everyone gets 8 gigs into their supermarket-PCs).

Anyway.

I remember upgrading my 8088 from 128 kB to 640 kB, it was about 50 EUR
(back then there was no EUR, sure) ..

I feel kinda old thinking of this ;-)

And today I got 2 new servers at a customer, 64 GB RAM each ... modern
times ...

At least there I know how to make use of it ...

At least this OT thread isn't as insanely OT as the checksum one :-)

My first computer was a Sinclair Mk14 - even earlier than the ZX80. You had to 
build it yourself and it had 256 bytes of memory. And a 7-segment LED 
calculator display. I could play moonlander on that :-)

I remember standing in front of two Sun servers with 4gb each a couple of 
years ago.
I was stuck in awe. So much ram. 

Today my desktop has 8gb - and I am thinking about 16 in the next 12 month.

Yes. I remember as well.

costs!"

What for? Just to get back to the initial topic of the thread ;-)

In fact I don't even feel very adventurous with those 64 GB per server
... the hardware/board would allow 128 GB and the OS/app even more ...

It somehow shifts ... back then 64/96/128/256 MEGAbytes were BIG, now we
just get used to swap the unit: GIGAbytes, yeah, *yawn*  ....

uuuh, I am OT ?? ;-)

Haven't checked the checksum-thread, does it use RAM ?? ;-)

Try that with 8gigs and 64bit ...

I have 3 of those monsters in my decommissioned stores that you are more than 
welcome to come and fetch them, you can awe them in the privacy of your own 
home all day :-)

Bring a 1 ton truck. Those beasts are big and heavy. Very heavy. It takes four
