Slow 1-2 Minute Load Times on New Server, More Ram?

[kirkhartstudios]

I'm a new owner of a dedicated server and recently I've been experiencing very slow load times on a site I just bought (the webpages themselves take 1-2 minutes to load sometimes). I just wanted to list my stats and see if anyone had any initial thoughts. I'm new to this game so any help is appreciated.

Server:
Core 2 Quad Q8200 2.33Ghz
4GB of Ram
2x1500GB SATAII drives with Raid 1

Daily Operations
The website receives roughly 1200 unique views per day. It's a file sharing site. You upload a file and then get a link to download it. It averages 750 downloads per day. Recently it's reached 700GB used out of 1100 available.

I know this tells you guys nothing in terms of actually CPU / Memory usage and processes but I'm just learning how to use Terminal on my Mac to see things like "top -s -c" etc. So if you have any commands for me to run, I'll gladly try them! I'm looking through this forum and reading on similar issues to mine.

Here is one command I've seen people request:

top -s -c
