How long have you had that particular page open? We changed those requests from 20 to 120 seconds about 2 weeks ago? We don't have any load problems at this time.  In fact we made changes that reduced the only load issues we were experiencing about 10-12 days ago. There's obviously going to be a little time involved in the load balancer figuring out the most accessible machine to hand the request to - but in my own testing I'm only seeing minimal differences between the time it takes Renderosity vs RuntimeDNA, Google, etc. when comparing similar pages - by similar I mean pages with lots of images to other site pages with lots of images or simple pages with minimal content to the same.
