Hi Nicolas,

this morning, working on the same table is much less painful.  I've run
the profile and did some movements and changes to the table and here is
the output from the profiler (I can send you the full report if you
wish).

I know that if I narrow the buffer to just the section (headline and
contents) that contains the table, the performance is
better. Anecdotally, it would seem that the performance degrades over
time so I wonder if there is a cache issue?

My gut feeling is that it is related to fontification as well.

I cannot send the actual table I am working on as it relates to grades
for students.  I will try to create a similar table with random entries.

thanks,
