In my limited experience ext4 as presented by Karmic is not db friendly. I had to carve my swap partition into a swap partition and an xfs partition to get better db performance. Try fsync=off first, but if that doesn't work then try a mini xfs.

- Possibly their config is different - they could have disabled the "fsync" parameter which turns the database to be not crashsafe anymore but much faster in some circumstances.
- Possibly you have much data in your template1 database? You could check whether
CREATE DATABASE speedtest TEMPLATE template1; takes more time than CREATE DATABASE speedtest TEMPLATE template0;.
You should issue both multiple times to ensure caching on the template database doesnt play a role.

Seems unlikely. Is starting psql near-instantaneus? Are you using "createdb" or are you issuing "CREATE DATABASE ..."?
