Allow me to repeat, my patches have nothing to do with the slowdown. If 
anything, they speed certain aspects up, including the way the 
scrollbars are updated, particularly with the top-level plots, and most 
recently the removal of the legacy topmost reordering which may need to 
be revisited later.

This is a slowdown in nw.js. I am not sure where but it is there. Try 
downloading the latest "stable" 2.11.0 release, run L2Ork Tweeter, or 
some other GUI-heavy patch, and then try the same by replacing the nw 
folder with the 0.46 or 0.47 and you will see that it opens up 
significantly slower. As Jonathan suggested, this needs to be profiled 
to figure out what is the bottleneck and then find a different approach 
and/or report it upstream for the nw folks to address/explain.
