Hi Michael,

Maybe.  I know that org's performance improves when I narrow the buffer
to just the section I am working on, when I work on long documents so
the lines above and below the table may affect things.

How long do you spend manipulating the table at any one time?  I have an
impression that performance degrades over time in a single session.  But
I have no evidence for this.  It's just an impression.

thanks,
