I setup the latest (as of the post date) Wordpress MU and everything seems to have gone fine. I setup a few test blogs for myself to make sure it would work fine for a few friends and they all worked fine.
I registered a new domain for it and put it on a Ubuntu based VMWare LAMP Appliance (VirtualAppliances.net) which I have used a lot before in the past with normal Wordpress blogs...
The problem... All my blogs so far work fine except one. When it gets hit, the browser just sits there "trying..." to bring the page up. After 8-10 seconds it comes up, then you click a header to go to that post, another 8-10 seconds, then it comes up. (I'm hitting it from my local network)
I went over to another blog on the SAME system and it's immediate and superfast. No problems with ANY of the other blogs.
I setup the DNS for my domain to send *.mydomain.com over to the WordPress MU installation which is what I read in the install.
I'm puzzled here as to why this ONE blog on the server is having all the trouble.
