Problems pre-generating the world

[daytimepanther]

I'm starting up a new modded server. I'm using kCauldron to run bukkit plugins along with the pack. This is how I always setup my servers but this time when generating the chunks to the world border (5000 radius, round), it starts off great but suddenly slows down tremendously. Specifically, from stating in console that 140 chunks had generated it then says after about 5 minutes its only generating 10-15 chunks. I tried using the forge mod port of this plugins but with the same results. Does anyone have any tips for generating a world before allowing players on the server?

I have no experience with plugins but I would try Admin Commands Toolbox or bdlib for that.
