If it takes longer loading then it is your connection. Our server is first rate with lots of memory and almost always runs at only 20% or less of it's capacity.
The forum loads almost instantly for me on DSL. I notice no difference day or night, evening or morning. The server is in Denver and I am in Florida, so it's not like I am close to the server or anything.
I think the key is DSL. DSL does not share resources with other users like Cable services do. With cable you have to share the resources with other users. That's why it is slower in the evening.
And if you're on dial up, well, sorry, but there's nothing you can do except wait.
