filesystem

How do I improve my file server performance. I've many large files in directories and how do I speed up access time? The -D option causes e2fsck to try to optimize all directories, either by reindexing them if the filesystem supports directory indexing, or by sorting and compressing directories for smaller directories.

Interesting article on how-to create additional swap space on your server after partition table has been written. The author had to expand swap and create a mountable /tmp partition on live production server. The how-to uses dd to create a "file" then mounts that file for swap and /tmp.
