For anyone interested, I emailed Gossamer Threads about this, had an email back, paid, and within an hour had the dual_apache set up installed, with absolutely huge performance improvements. Everything really flies now. Amazing speed improvement. Times which used to send server load up to 30 and above now don't even tax the server. Dynamic pages load as fast as HTML pages (no noticeable difference).

Also, while GT were on my server, they also managed to reduce the footprint of an apache process down from 8mb to about 2mb.

I had thought about getting the hosting techs to do it, but GT also put in custom scripting specific to a Links SQL set up, which they would have never been able to do.

So, very recommended, and very much cheaper than getting a hardware upgrade.
