Hello, I am working with a table. It has approximately 130 rows and 20 columns so it's not huge but also not small. Three columns are text but the rest are all numbers with some degree of sparsity. Instrumenting org while working on this table, manipulating the entries in just one row, I get the following:
| Function | calls | elapsed time | average time | |--------------------------+-------+--------------+--------------| | org-cycle | 20 | 41.550963140 | 2.0775481570 | | org-table-next-field | 20 | 41.544266727 | 2.0772133363 | | org-table-align | 5 | 41.470595702 | 8.2941191404 | | org-mode-flyspell-verify | 52 | 1.0647362189 | 0.0204756965 | | org-do-latex-and-related | 21 | 0.6656267140 | 0.0316965101 | | org-element-at-point | 125 | 0.6356939890 | 0.0050855519 | | org-element--parse-to | 125 | 0.6086256940 | 0.0048690055 | | org-element--cache-put | 1399 | 0.4963533770 | 0.0003547915 | >From this, it would seem that the table align function is killing the performance. 8 seconds per call? On an 8 core Intel(R) Core(TM) i7-2760QM CPU @ 2.40GHz... so not my wee Pandora where I expect slowness! This is with a not quite up to date org. I'm avoiding upgrading as I am preparing material for teaching which starts soon and I don't want to run into issues due to changes in org... so I apologise if things have changed recently. This performance issue has existed for quite some time now, however. Any suggestions on speeding things up? Thanks, eric -- : Eric S Fraga (0xFFFCF67D), Emacs 25.0.94.1, Org release_8.3.5-1070-g190476
