Hi

Are there any standard things that I can do to tune my linux on the laptop ?
I have a vaio qr10.
Everything runs nice only the battery management (I will see in 2.5 ;)) and 
the speed. It has only 64 MB RAM and kde needs more.
What can I do from the kernel side to make linux faster ?

I use always the current 2.4 kernel
Ext2
Xfree 4.1



thanks
have fun

hi

have you tried compiling the sources with gcc optimisation options?
usually boosts applications a bit in the range from 5-10%.
optimisation can slow down your compile time seriously when having a
slower cpu.

The cpu is not the problem. It is a 650 Mhz Celeron.
I know there are some options for gcc, g++ but I don't know them.
Is there a website for this kind of gcc use or other information ?

Maybe I try to compile kde with gcc 3.1 and opti options, maybe that helps.

Just curious, have you tried blackbox at all as a desktop environment? 
 From what I've seen it's a pretty slick environment, while still being 
quite light on the system resources and looking good.  If you're running 
slackware you can get the slackware package (YES slackware has a package 
manager...) from 
ftp.slackware.com/pub/slackware/slackware-current/extra/blackbox-0.62.1/

The home page for blackbox is http://blackboxwm.sourceforge.net


Good Luck

[Patrick Onegin]

the main options are described in the gcc manual.
you'll find options here:

http://gcc.gnu.org/onlinedocs/gcc-2.95.3/gcc_2.html#SEC16

optimization options are here:

Hey! There's a thought, gcc 3.1 has an option, I think -Os, to make the
code as small as possible, as well as the usual other things. I think CPU
is the problem for running things and memory for graphics, sort of the
worst of all possible worlds.

Can you show us the output of "ps aux"?

Re: Make it fast

Hi

At the moment I am running 2.5.x and it is a little faster.
Also I switched to blackbox because kde needs too much mem. I don't have many 
processes running, I removed every thing I don't need from the startup 
scripts (apache, webmin...).

I will buy some mem if I have more money ;)

thanks

Consider a less costly desktop.  My 25 BogoMips 486 24 MB laptop runs
just fine with fvwm (Slackware).  You also might turn off whatever icons,
dancing girls, and other things that you don't need.  Doing a "top" or
"ps -axlww | more" will show what is using CPU and memory.

Also, some programs, most notably X and Netscrape leak memory over time.
Thus, you will want to shut down Netscrape every day or two and probably
shut down X weekly to free up the leaked memory.

The problem is: I want a modern desktop.

At the moment I'm compiling kde 3 drom cvs head to be sure that I have the 
newest version with lesser mem leaks.
I tried to remove all eye-candy things but it is slow.
Also I don't use netscape.


Now my desktop is tuned but I have to tune Linux.
I already remove daemons (e.g. webmin).
I can't tune more. There is only the Linux kernel which is a normal build so I 
thought there may be some things that I can set in the kernel config to make 
it a bit faster.

Maybe I should try 2.5 ?
This laptop has no critical mission.

I don't doubt that! You really seem to be out of memory, does `free' show
a lot of swap used? I have 128 in one laptop and it's still marginal,
while a 486-25 with 12MB is usable with a 2.0 kernel and fvwm95 (no, I'm
not a Windows user, I like it better than plain fvwm).

Try 2.4.19-pre10-ac2 + preempt, or the new 2.4.19-pre10aa4. Turn off
everything you don't absolutely need and then make everything you don't
need all the time a module. That means serial, parallel, ppp, sound if you
have it, all network and netfilter, nfs, samba, modularize it all. If you
do much with playing CDs, grab the "CD audio via DMA" patch floating
around and drop that in, it will save you some CPU.

I somehow suspected that.

I recommend Opera anyway.

I suspect that you have reached a fundamental limitation and that 2.5
will provide no advantage and maybe even be worse since it has other
stuff in it that probably take up more space.  Less windows may help
a little.  Building a custom kernel (if you have not already) that does
not have drivers and things that you will not be using also may help.
If you can add memory, that will help too but 64 MB should be reasonable.
Btw, I'm not an expert on this area of configuration so someone else
may have other ideas.

Since he will run KDE I suspect Konquerer is the browser of choice. I do
like it, although I'm familiar with NS.
