EDIT:
I did a quick search and found a thread in another forum that suggested this:
Also, since their is a low amount of RAM available for a Linux distro you can speed up your system by disabling process on the system.
Here are a few I disabled in Ubuntu:
# Evolution Alarm Notifier
# Network Manager
# Power Manager
# Print Queue Applet
# Check for new hardware drivers
# Tracker + Tracker Applet
# Visual Assistance
Here are some process you can disable in YDL:
* anacron
* atd
* avahi-daemon
* bluetooth (if you don't use it)
* cpuspeed
* cups
* hidd
* hplip
* ip6tables
* isdn
* mcstrans
* mdmonitor
* nfslock
* pcscd
* rpcbind
* rpcgssd
* rpcimapd
* sendmail
* smartd
* sshd
So, I'm going to go ahead and disable sendmail since it doesn't seem to serve me a useful purpose. Kind of surprised it was on by default. Not sure about some of the other ones he mentions above since I used a few of those myself. Always good to try and free up some resources!
EDIT again. Sorry I did some more searching and found another valuable thread regarding this issue. My first searches for sendmail and services by topic only didn't turn up anything.
