As predicted in the previous post, moving and upgrading WordPress was easy, fast and pleasant.

However, one thing hit me during the process was the memory consumption of Apache. Currently, my 256MB slice has only the OS, Apache and sshd running, but there is almost no free memory left. It will probably be a serious problem later on, so I’m going to take a look at some lightweight web servers. The candidates so far are: lighttpd, Cherokee and Nginx.
