Although in this stage we pass numbers around --- future versions might use light user data, so never depend on what direct function --- return. Using the direct approach had some speed advantages but you loose the key --- based access. The speed gain is only measurable in cases with lots of access. For --- instance when typesettign arabic with advanced fonts, we're talking of many millions --- of function calls and there we can get a 30\% or more speedup. On average complex --- \CONTEXT\ runs the gain can be 10\% to 15\% percent. Because mixing the two models --- (here we call then nodes and nuts) is not possible you need to cast either way which --- has a penalty. Also, error messages in nuts mode are less clear and \LUATEX\ will --- often simply abort when you make mistakes of mix the models. So, development (at least --- in \CONTEXT) can be done in node mode and not in nuts mode. Only robust code will --- be turned nuts afterwards and quite likely not all code. The official \LUATEX\ api --- to nodes is userdata! --- --- Listening to 'lunatic soul' at the same time helped wrapping my mind around the mixed --- usage of both models. Just for the record: the potential of the direct approach only --- became clear after experimenting for weeks and partly adapting code. It is one of those --- (sub)projects where you afterwards wonder if it was worth the trouble, but users that --- rely on lots of complex functionality and font support will probably notice the speedup. --- --- luatex luajittex --- ------------- ----- -------------------- --------------------------------- --- name pages old new pct old new pct --- ------------- ----- -------------------- --------------------------------- --- fonts-mkiv 166 9.3 7.7/7.4 17.2 7.4 (37.5) 5.9/5.7 (55.6) 20.3 --- about 60 3.3 2.7/2.6 20.4 2.5 (39.5) 2.1 (57.0) 23.4 --- arabic-001 61 25.3 15.8 18.2 15.3 (46.7) 6.8 (54.7) 16.0 --- torture-001 300 21.4 11.4 24.2 13.9 (35.0) 6.3 (44.7) 22.2 --- --- so: --- --- - we run around 20% faster on documents of average complexity and gain more when --- dealing with scripts like arabic and such --- - luajittex benefits a bit more so a luajittex job can (in principle) now be much --- faster --- - if we reason backwards, and take luajittex as norm we get 1:2:3 on some jobs for --- luajittex direct:luatex direct:luatex normal i.e. we can be 3 times faster --- - keep in mind that these are tex/lua runs so the real gain at the lua end is much --- larger --- --- Because we can fake direct mode a little bit by using the fast getfield and setfield --- at the cost of wrapped getid and alike, we still are running quite ok.
