it depends on usage: if you want wysiwyg you should use a desk top publishing program or a word processor if you type an occasional letter or whatever small document, use a word processor if you do automated typesetting, you can use tex if you make very large and complex docs, you can use tex if you focus on writing and occasionally need to see the output (simply because you trust the system to be able to deal with it) you can also use tex
compilation time, you can have a cup of tea and enjoy the sunshine... Anyway, t-zhspacing is much faster than lualatex. but 1 minutes to compile a 100 pages document is still too long)
it all depends on what you use and want to achieve; also lualatex is not relevant when we discuss for instance context mkiv which follows different routes (btw, mk.pdf takes some 55 seconds for a 300+ page document and that's 10 seconds for page faulting so on another machine it runs faster; and mk uses a lot of large fonts + some demanding typesetting like arabic)
But one thing is always puzzling me: When open MS Word, it consumes 16MB memory, then I typeset Chinese text in 10 different Chinese fonts (all are 10M+ each), word only consumes 30MB memory. If I do that in LuaTeX it will consume almost 1G memory... why MS Word parses fonts and renders text so fast while consumes such less memory? Can TeX do that too?
word will use shared libs so you don't see all mem used; if a file on disk is 10 meg and you use several of them, i'm pretty sure that such a font unpacked takes some mem somewhere; also, the renderer is embedded in the operating system; in mkiv we maintain a table representation and since fonts hame many subtables it takes mem also, if word renders fast and efficient and does the job right, you don't need tex at all -) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
