Are you serious? Are you telling me that rounded corners are going to slow website loading to a crawl?

Please refer to this.

With firebug, it's saying that to load the main page I need 91 HTTP requests, taking 22 seconds, and is 860KB to download with nothing cached. The vbulletin default theme is 64 requests and 280 KB. Mine is 32 requests 322KB. That's way too many requests and way too much to download.

YSlow tells a similar tale also,

Grade of E, I'm surprised it's not F.

You have Zero Caching on almost all of your files. Every time someone loads the page they need to request the files again. That's wasteful.

Before you start pointing fingers at vbulletin you need to do some serious optimization.
