Linux SSD 优化 -- for ubuntu 10.10 64bit
The conf I make to make less write to SSD, thus make it run a little faster. It’s quite dangerous, since log are not kept and other compromises.
On my dev machine, which has 8G memory and a SSD, works quite good, trade memory and safety for speed.
All my source code are sync to remote git repository. On my dev machine, which has nothing but code, I already have safety.
- 修改/etc/fstab, 为每个分区加上 noatime,data=writeback。/dev/sda1为/ 分区
sudo tune2fs -o journal_data_writeback /dev/sda1- edit /etc/fstab：
tmpfs /tmp tmpfs defaults 0 0
tmpfs /var/log tmpfs defaults 0 0
tmpfs /var/tmp tmpfs defaults 0 0- 修改/etc/default/grub
GRUB_CMDLINE_LINUX="elevator=noop"
GRUB_TERMINAL=console #not for speed, it looks better
GRUB_TIMEOUT=2- before using apt-get:
sudo mount tmpfs /var/cache/apt/archives -t tmpfs
mkdir /var/cache/apt/archives/partial- browser cache:
- firefox: browser.cache.disk.parent_directory = /tmp
- chrome: –user-data-dir=/tmp
