Need suggestions to reduce server load by disabling useless features?

[jani]

I have disabled some plugins and / or features on my webmaster forum to not put extra load on my server.

I have got good VPS but I don't want to put extra load for the things that are not very useful for the readers and/or members.

I like to know what features will you disable if you try to reduce the server load on your forum?
