Hi, I'm (occasionally) trying to 'minimize' bottlenecks in the context / luametatex code. This is kind of hard because both are rather efficient already. On regular runs performance is probably okay but there are cases when one has a large complex document (e.g. with many tables) or has many runs (e.g. thousands of documents in one go). In that case even minor speedups can accumulate and become measurable (esp on vms and runs over a network). It can safe time and also energy (which can matter todays KWh pricing). So the challenge is how to determine bottlenecks. Are there users on this list that have document runs of more than 10 seconds (as reference: the luametatex manual takes < 9 seconds for 350 pages and loads plenty fonts and has many tables) or have many (small) runs and are annoyed by the runtime? And if so, what does one guess are the bottlenecks? Hans ps. Much runtime is spent in Lua and there is not that much we can do about making that faster. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

In any case, the processing time has been improving greatly over the last couple of years, and LMTX is significantly faster that MkIV in all of my work. sure, that is to be expected although it depends a bit on the use case, for instance the backend is slower (but does much more) so initially lmtx was actually slower but at some point we started gaining (and i can
these stats are an indication because below a threshold (time accuracy) nothing is measured probably gain a little more) i wonder why directions bump time because much of what tex does is sort of agnostic for directions (the backend needs more time but i don't see that in your stats) when you run with --profile you get a much slower run but might get some info from the extra log Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

can you check compact mode .. when compact fonts are not enabled, do you get the same
mkiv lua stats > font engine: otf 3.131, afm 1.513, tfm 1.000, 84 instances, 67 shared in backend, 3 common vectors, 64 common hashes,
i wonder why so many instances
mkiv lua stats > node memory usage: 6869 attribute, 4608 dir, 4612 glue, 84 gluespec, 2304 glyph, 3072 hlist, 3 kern, 647 mathspec, 5 penalty, 2 temp
this is suspicious ... i fixed a dir leak recently but having 3K boxes dangling ...
In neither case do the sum of the times listed in the stats come close to the total runtime (in the second example, 14.774 seconds of 23.057 are accounted), so there are other unidentified processes involved.
these stats are an indication because below a threshold (time accuracy) nothing is measured
In any case, the processing time has been improving greatly over the last couple of years, and LMTX is significantly faster that MkIV in all of my work. sure, that is to be expected although it depends a bit on the use case, for instance the backend is slower (but does much more) so initially lmtx was actually slower but at some point we started gaining (and i can probably gain a little more)
i wonder why directions bump time because much of what tex does is sort of agnostic for directions (the backend needs more time but i don't see that in your stats)
when you run with --profile you get a much slower run but might get some info from the extra log

that's quite decent i guess the fact that we have multiple runs make any optimization count for more than on a single run thanks for testing Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

minimal difference.
the differences are mostly in loading times (say 10 times some cjk font or math font) the best way to check if compact mode was active is to check if the number of font instances changed for the record: compact mode actually has more overhead in the engine but it is compensated by other aspects of it Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

It means that some lines at the end of a page slip in the following pages. Since there are forced page breaks and chapters starting at odd pages, they are minimal differences that result in pages with only 1 or 2 lines of text, or white even pages. I don't know whether this is expected as the effect of \enableexperiments[fonts.compact] only. I expected a difference between version 2020-04-26 and the latest one, because it always happened when I tested the newest versions, though there has been a convergence of the resulting pdf and the differences are minimal now (between version 2020-04-26 and 2022-12-15). But it did not happen, the resulting pages are still 1026.

It's better, but the pages are 1032 against 1026.
It means that some lines at the end of a page slip in the following pages. Since there are forced page breaks and chapters starting at odd pages, they are minimal differences that result in pages with only 1 or 2 lines of text, or white even pages.
I don't know whether this is expected as the effect of \enableexperiments[fonts.compact] only.
i has to do with sightly different accuracy as we scale on the fly ... (we are somewhat stuck to this tex scaling model where 1000 = 1.0 but maybe it's time to revision that
I expected a difference between version 2020-04-26 and the latest one, because it always happened when I tested the newest versions, though there has been a convergence of the resulting pdf and the differences are minimal now (between version 2020-04-26 and 2022-12-15). But it did not happen, the resulting pages are still 1026.
most of this has to do with fonts .. we bumped the accuracy a bit recently (to cope better with radical line alignment in some radicals)
Here's the results in short:
ConTeXt 2020-04-26:
runtime: 172.721 seconds, 1026 processed pages, 1026 shipped pages, 5.940 pages/second
ConTeXt 2022-12-15:
runtime: 130.080 seconds, 1026 processed pages, 1026 shipped pages, 7.887 pages/second
ConTeXt 2022-12-15 with \enableexperiments[fonts.compact]:
runtime: 114.917 seconds, 1032 processed pages, 1032 shipped pages, 8.980 pages/second ok, so in your case compact font mode helps ... you could enable it in cont-loc.mkxl (we might switch to that mode by default in the future) )
