 First "post-holiday" problem report ! :)
 
I had to revert to 77 as 78b performance is slower overall (and, of course, more CPU intensive) and too slow for me to work on it all day long.
Editing fields in manage fields dialog, grid refresh,  equations, changing format, erasing items, moving/drag-drop items from one grid to another (this used to be much much more speedy) etc.
It's pretty sluggish here. I'd say about 2 times slower, average.
 
I won't go into a more detailed explanation of what's fast or not as it's pretty much the same issues I'm experiencing on a regular basis. (77 isn't that speedy either, but it's faster. 76 was definitely the fastest (equations and grid updates were much faster).
