Hello,
I'm facing a slowness while using org-columns mode on a fairly large
file of mine with around 700 lines split between 3 outlines.
My column definition is the following:
:PROPERTIES:
:COLUMNS: %50ITEM %Director %Year %WATCHED{X/}
:WATCHED_ALL: "[ ]" "[X]"
:END:
The slowness is observed when I change the value of the WATCHED property
to the next value. Attached you can find the point where I found the
slowness after elp-instrumenting everything I could think of:
org-columns-compute 1 4.310940636 4.310940636

org-add-props 6 4.5256e-05 7.542...e-06
It seems strange to me that switching to the next value of a cell, a
call to org-columns-compute is needed. As you can see
org-get-property-block is calles 786 times (which is rougly the number of
all-level entries in this particular org file).
Is there any way to make things faster?
Best Regards,
Leonidas Tsampros

That's because one of the feature of the column view is to sum the
values in each entry and show the sum on the top of the colum; so
parsing all the values is needed here for computing the sum.

I'm afraid not. At least not with a simple fix.
Best,
