Adding some data: my table is at line 8438 in the buffer but character
position 398345 (I have very long lines as I use visual-line-mode in org
exclusively with org-indent).  I do use utf-8 encoding.

I have just tried updating the table on a different laptop (i7-2760, 8
cores, 8 GB RAM, Ubuntu) and it was very fast.  

The two laptops are running different versions of emacs (tracking latest
emacs developments on Ubuntu and Debian testing lead to different
versions unfortunately) so my gut feeling is that there is an emacs
issue here and possibly one related to utf-8 as Daniel suggests.

I'll try to do more instrumenting on my other laptop when I get a
chance.

thanks all,
eric
