Thinkpad x40 without harddisk, 1GB of RAM. The hard-disks for these models are very slow, rare and expensive. This is why I installed Ubuntu 11.10 onto the USB. The system will be used for net - FF, and some office docs editing. If possible, I might setup a second PC, used for XBMC.
I have tried live Ubuntu USBs with the same PC and USB, and the setup is OK. I am limited to 4 GBs, though. This is why I chose to perform normal install.
The system feels slow, and freezes every other second. I have no swap, only one root partition.
What I have tried:
sudo apt-get install preload
Use memory instead of disk
Add these lines to /etc/sysctl.conf, and reboot.
vm.swappiness = 0 vm.dirty_background_ratio = 20 vm.dirty_expire_centisecs = 0 vm.dirty_ratio = 80 vm.dirty_writeback_centisecs = 0
Mount /tmp onto ramdisk Code:
mkdir /dev/shm/tmp chmod 1777 /dev/shm/tmp mount --bind /dev/shm/tmp /tmp
Still, the system is slow to the point of being unusable. Are there any other tweaks that can be done. I read that some parts of the system might be mounted into RAM, and that would be beneficial, but which parts and how to do that. I also read that compressing parts of the system might help, I dont know how to do that , too
