More thread creep. Sorry Lisa
The difference between the load .threads lays on a server and .threads is can be considerable depending on the size and scale of your board.
Threads is not flat file, there is considerably less I/O as compared to a .classic site of the same size and traffic. Sure, some of the queries that .classic does can get heavy (which by their description is thier preference) but in comparison to .classic's search or Recent Vistors it's not as much a problem.
This server hosts ubbdev and threadsdev. The traffic is probably relatively close to even though I haven't checked this lately. threadsdev is definately the easier of the two on the server.
I love .classic, I'm the Product Manager
So don't take the above as me trying to beat down .classic. What I am trying to convey is that all things being equal your .threads board will be easier on a properly configured server than .classic. Especially as you scale up. It shouldn't cost MORE to run, it should cost less. Especially given that it's (.threads) all .css and thus each page is lighter. The only caveat is that your board just might get more popular. That'll cause it to use more resources
