From Fedora Project Wiki

This page is intended to gather performance related feedback for running Fedora 10 Live images on the XO.

Service Run-level Changes

What system daemons are started that aren't needed? For example, bluetooth ... there is no bluetooth hardware on the XO.

GNOME Desktop Session Changes

Kernel tunables?

Packaging Changes

Image Generation

Overlay Storage

Using the --overlay-size-mb parameter to the livecd-iso-to-disk script is recommended for 2 reasons.

  1. Any changes to your live image are saved to the SD card (instead of memory). These changes will remain upon reboot.
  2. It improves performance because there ends up being less memory pressure.

A potential drawback might be that more writes are happening to your SD media, which may lower the life expectancy of the SD media.
