I run a vBulletin forum on what I would think should be an adequate VPS. The board is my first and is still quite new (launched 9/8/06). Anyway, I am really running into some issues.
First off, I am so green to the VPS world. I've read through this board until I'm cross-eyed and I know most of what I'm asking is going to be somewhat repetitive, but I just want to make sure I haven't missed anything crucial.
Here are my server specs:

Ok, so with all that stated... I keep getting hpptd failures and can't figure out why. During certain times of the day my site is unbearably slow. The worst server load I've seen is this evening:
2.10 0.88 0.59 | 48 Users Online (18 members and 30 guests)
1.39 0.85 0.59 | 49 Users Online (19 members and 30 guests)
1.07 0.81 0.58 | 49 Users Online (19 members and 30 guests)
Honestly, I don't know what I'm missing... How can having so few users online at one time cause my site to respond so poorly? ETA: This is not a media rich site.
Tech support (host) has stated that they haven't had any issues with pages loading, but I certainly have as have some of my members. Really what concerns me are the httpd failures. The service restarts but I haven't been able to get an answer as to why it fails. Also my site is pretty much down during the failure and restart which is annoying to say the least.
I've checked default vB scheduled tasks and have disabled those that I do not need. I've tried to disable anything that is overly server/processor intensive while still keeping the desired functionality of my board. I've gone through my installed hacks and no luck there with any sort of resolution. I am assuming I need to evaluate the necessity of cPanel, possibly install eAccelerator and upgrade RAM(?) again... Is there anything else you guys could recommend? I'd really appreciate any advice I could get.
Oh and also, do many people hire server management companies to manage their VPS? I guess I always assumed that SMs worked in the dedicated server world.
Thanks in advance and sorry for the book!
