Which files/directories can I move to RAM drive to have the system working faster?

I'm planning to upgrade my laptop's memory to 8GB soon, so I'll have some fast memory to use. How to configure the system to work optimal with this memory?

The next changes I consider next are:
- upgrading hard drive to SSD
- start using virtualization (I need Windows sometimes)

Edit:

Maybe I can sacrifice boot time, and copy some files to RAM drive during boot?

To mount /tmp /var/log and /var/tmp in RAM. Add these lines to the end of fstab to mount /tmp (temporary files) as tmpfs (temporary file system):

tmpfs /tmp     tmpfs defaults,noatime,mode=1777 0 0

tmpfs /var/log tmpfs defaults,noatime,mode=1777 0 0

tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0

Save, then: sudo mount -a

Reboot for the changes to take effect. Running df, you should see a new line with /tmp, /var/tmp and /var/logs mounted on tmpfs.

Note: all log files will be lost after a reboot, to back them up manually run this in terminal:

rsync -av /var/log/* ~/saved_logfiles
