hi everybody,
I have a table with 15 columns and 500 rows. One of the columns is a
URL.
org-mode is hanging while exporting the table. It does not seem to
crash, but it is taking a significant amount of time. The worst part is
that it does not appear to be linear.
80 rows -> 17 seconds
160 rows (same 80 rows duplicated) -> 58 seconds
160 rows, 8 columns -> 21 seconds (it seems to not matter which columns
there are).
I wonder if this is expected behaviour. Given that org does not sort the
tables, why does the time increase non-linearly to the size of the
table?
If interested, I can make the table available.
thanks a lot!

A working example that reproduces the issue always helps. If you could
post the table (of course after removing sensitive/private information)
it would be great help for the developers and testers.
Thanks,

Here is a trivial example:
http://turingmachine.org/~dmg/temp/bigTable.org
(you can do anything with this file, including adding it to any battery
of tests in the future).
- Latex works well (export within a couple of seconds)
- ASCII, HTML, Markdown (based on html so no surpise) take more than a
minute....
Does anybody know where the processing might be taking time?
thanks again,

As ELP shows, there are a couple of functions involed. I'm not surprised
though.
I am going to have a look at this.
Thanks for the example.

I pushed a commit caching the results of some table functions. Export of
large tables should be a lot faster (I get 6 s now; it was 90 s before).

Hi Nicolas,
thank you very much. This has resolved my issue. I can now export an org file
with these tables in few seconds.
thank you,
