Hi there,
are there any optimizations I can do to further utilize large memory. I have 8 G memory on my laptop and I installed ubuntu 11.10 64bit. I Now the system only use 10% of my memory.
Thank you.

What about running more than one Virtual Machine?
Then what about using Ramdisk?
You would be able to refer this post and its thread.

you can tweak the swappiness if you like, but the default settings are already optimized

You could install preload
Slows down initial boot a tad for some people, but it preloads apps as it learns what you use. Depending on the speed of your system you may see a difference. If not you just have more ram than you need. I have 4GB's and even when I run a VM I never use all my RAM let alone touch swap. Even compiling a kernel I don't go over 4GB's.Code:sudo apt-get install preload
Loading an application takes x seconds. If you use preload then you shunt those x seconds to the boot process rather than while you are using the desktop. There is no change in x but perhaps a psychological benefit (a small increase in boot time is less frustrating than a laggy desktop).
Decrease your swappiness to 10. I don't think you will see any difference in memory usage but you should see a vast improvement in performance. Make sure you read the whole page (it's on the bottom).

preload runs all the time. it reanalyzes every 20 seconds if it should preload anything else (you can change that in the preload.conf file). ureadahead is the one that only runs during the boot process.
If you don't use the swap partition does decreasing swappiness really make a difference? I only have 4GB's of RAM but I never use the swap partition. Free always looks like this for me:Originally Posted by Bobhuber
