Cream 0.28 performance issues

[<mic...@gs...>]

Hello dear Cream users!!
Wondering if others are seeing similar performance problems and can offer 
words of advice or solace...
I open a 2.5 meg text file from a server share. When I use the arrow keys 
scroll to the right (about 15 chars, about mid-line), and then use the 
arrow keys to scroll down, the cursor moves in fits in starts, changing 
from a bar cursor to a red block, with the status bar alternating between 
"I" and "N". I cannot scroll more than 5 or 6 lines at a time, I cannot 
scroll smoothly up and down the file at all.

Am I missing some setting, some $cream variable, some wrapping setting or 
syntax coloring setting, that is causing this performance issue? Regular 
VIM does not seem to suffer this problem, but then again it is not 
toggling between insert and normal mode. Generally speaking, I think that 
the text editor should be able to scroll at superhuman speeds through 
files of any size; I can understand that syntax coloring takes some work, 
as does wrapping, as the editor handles the offscreen/onscreen buffer 
stuff, but just text should be fast both up and down.

While I drink my coffee black, I am enjoying cream in my Vim!
