Unfortunately Dalaran is just like Shattrath in its time and that is it insanely taxing on good performance. Yes, I was very well aware of this when I designed the server. But, I realized after a while that in order to create a fun "Wrath" feeling server, the objective was to not put the mall in Tanaris. That just... kills the feeling of the expansion. I saw one server I was comparing, and the mall was in Desolace. Horde were coming in killing new players that had just logged on in starter gear. It was just a terrible design and I wanted something that REMINDED me of the game. Where was that? Dalaran. It was everybody's hearth if they played during retail. Dalaran was the city that had everything you needed. I wanted the mall to fit there, so we've designed in to fit the city quite well.

I hope you're able to still run the game. I'm sure the settings will have to be turned down a bit. Luckily, WoW does really allow you to turn off a lot and get a decent performance out of it for lower-end computers. Anywho, wish you the best of luck in your upgrades!
