Some timings on a 3-4 (?) year old netbook with Intel N450 Atom @1.66GHz
dual core powered:
With old org, actually from October 2012 (!) as this system acts as a
cloud server for me so I don't actually use it interactively much:
| org-agenda-to-appt | 1 | 12.525722775 | 12.525722775 |
| org-agenda-prepare-buffers | 2 | 10.719484861 | 5.3597424305 |
| org-agenda-get-day-entries | 15 | 1.4113181819 | 0.0940878787 |
| org-agenda-get-scheduled | 15 | 1.032943071 | 0.0688628714 |
| org-agenda-get-deadlines | 14 | 0.2688785840 | 0.0192056131 |
| org-agenda-skip | 797 | 0.1879489969 | 0.0002358205 |
and with up to date org as of a few minutes ago:
| org-agenda-to-appt | 1 | 9.168879079 | 9.168879079 |
| org-agenda-prepare-buffers | 2 | 8.1717637810 | 4.0858818905 |
| org-agenda-get-day-entries | 15 | 0.5261351449 | 0.0350756763 |
| org-agenda-get-deadlines | 14 | 0.253867925 | 0.0181334232 |
| org-agenda-get-scheduled | 15 | 0.1835072029 | 0.0122338135 |
| org-agenda-skip | 797 | 0.0482942050 | 6.059...e-05 |
I.e. an approximately 25% reduction in time overall so I think
org-agenda is significantly faster (okay, not orders of magnitude) but
the time taken is dominated by org-agenda-prepare-buffers on this
system.
However, more interestingly, on a 1 year old desktop computer Intel Core
i5-2500 @ 3.30 GHz, I get very different behaviour:
| org-agenda-to-appt | 1 | 0.182718048 | 0.182718048 |
| org-agenda-get-day-entries | 14 | 0.095832824 | 0.0068452017 |
| org-agenda-prepare-buffers | 1 | 0.086104933 | 0.086104933 |
| org-agenda-get-scheduled | 14 | 0.067475949 | 0.0048197106 |
| org-agenda-skip | 794 | 0.0475198030 | 5.984...e-05 |
| org-agenda-get-deadlines | 14 | 0.014998552 | 0.0010713251 |
[note: slightly different agenda files as the cloud server copy of my
agenda files is a couple of hours behind my desktop]
Notice the big change in org-agenda-prepare-buffers relative to the
other calls. Disk performance is almost likely the key here and I think
the recent improvements are quite dramatic but I haven't had a chance to
time these yet.
