Unfortunately, bottleneck was never one of the mods causing too much cpu usage, but less is better, and you can't beat no scripting overhead! I certainly do like the responsiveness, and the settings are absolutely adequate for me! Thanks a lot for your efforts!
The UPS drain with bottleneck isn't too bad if you keep the update rate low. However, this has the side effect of making the mod more sluggish to respond to changes in status. BNL removes that overhead, but it also will instantly respond to status changes regardless of the number of entities. This latter point is what I feel is the most important difference.
