I made a post on my own journal that talks about the scalability/load/capacity of Dreamwidth. The short summary is that we're nowhere near our ultimate capacity on anything and the few things that have started to hit capacity are being expanded. I am very comfortable with our current and future status!

More details here:

I'm going to disable comments here and ask that if you want to comment/ask questions/etc that you do it over there on the relevant post.

Thank you!
