Thanks for the information, could you please clarify what "entry" means? Does it
mean org headline, or a row in an org-table?

I guess the "entries" here mean the table rows right? Please confirm.

I was aware that my "emacs -Q" test was done against org-mode version 8.2.x.
However, I use the latest org-mode from Git everyday. For example, the version
I'm currently using is (from M-x org-version): "Org-mode version 8.3beta
(release_8.3beta-509-g86ec0a.dirty @ /usr/local/share/emacs/site-lisp/org/)". So
apparently the problem had never been addressed.

Meanwhile, I suggest to insert some subsections in your file.
What do you mean by "insert some subsections"?


Thanks

A few months ago I tried Emacs 24.4 and was disappointed because almost all of

Emacs 24.4 gets officially released, I finally switched over. However, the
problems I had several months ago were still there, i.e., in a big file,
org-table operations are at least ten times slower. I tried profiling it but
didn't help much. So I decided to report the issue here.

In summery, the file "test.org" has more than 5000 org-table tables, each table
has a formula. If you move the point to the tables not too far away from the
beginning of the buffer and press "C-c C-c" on the formula line, you will notice
that the speed is very fast which is great. However, if you move the point far
away enough from the beginning of the buffer (move to the end for example), you
will find that "C-c C-c" on the formula line becomes much slower.

Many other operations are also very slow. However, because I haven't been able
to create the ECMs for those operations yet, lets focus on this one
first.
I think Org 8.3 should improve the situation. Please test it if you can.

IIRC Carsten Dominik made the following observation: org tables are extremely slow if they are used as workbooks/spreadsheets and there are many entries (many is undefined). He recommended that a spreadsheet program in such situations.

I learned that the hard way when I had one table - four columns, three simple addition formulas with about 1,000 entries. It seemed an eternity before the addition was completed.
