I switched from Typo to Wordpress . I thought it would run a little faster on the 64MB VPS i use on my server. But WP uses MySQL as a backend and that doesn't really help.
Apache is also quite a memory hog on systems with low memory, but with some Apache and MySQL tuning my blog isn't going OOM anymore :).
I guess Apache and MySQL are a little to heavy on resources. I'm going to tune some more, but if that doesn't help much I'm switching to LightTPD instead of Apache.
Sorry if thing run a little slow for the moment....
