Hi There Zentz,
Yeah, in that case I would definitely start by adding RAM.
I am not all that familiar with Debian and if it supports PAE (RAM addressing above 4GB).
But at very least it should handle 4GB (8GB would be better if supported).
RAM is relatively cheap these days and 2GB is way too little for a dual zeon box which is obviously under a heavy load.
With the added RAM, Apache can cache the most requested files and significantly improve the processor load (load averages).
Best regards,
Archer
