I'm running Chromium browser (the open source port of Google Chrome) on Crunchbang Linux, and I've just discovered the following tweak which seems to have given me a significant speed boost.
The Asus has 1GB of RAM, so I've created a 256MB ramdisk on /media/ramdisk (crunchbang doesn't seem to use much RAM), and told chromium to put its cache there. Since doing so I'm not spending nearly as much time looking at the words "waiting for cache" in the bottom left corner before webpages load.
Here's how I did it:
Open a terminal and type (as root)
mkdir -p /media/ramdisk
mount -t tmpfs -o size=256M tmpfs /media/ramdisk
Which will give you a 256MB ram drive mounted on /media/ramdisk. To make this permanent you can add the following line to /etc/fstab
none /media/ramdisk tmpfs defaults,size=256m 1 2
Then all you need to do is tell chromium to use that location for its cache, by modifying the shortcut or menu item that launches your browser to:
On Crunchbang, I did this by editing:
Then you're all done. Assuming your internet connection is quick enough, your netbook won't hold you up waiting for cache or writing to disk when you load webpages. Let me know if it worked for you in the comments.
