typescript and memory usage

typescript and memory usage

[Antoine Junod]

Hello list,

Thanks to Hans, Hraban, Wolfgang and Aditya, I've successfully played
with typescripts and Garamond PP as provided by Adobe with luatex.

But I still have a little question :) By reducing my typescript to the
strict minimum, as below, I'm still using 232 Mo (sic) of ram. My
document test only contains nothing but a \switchtobodyfont but it
takes 8.7 seconds to compile on a 4000 bogomips machine (athlon
2400+).

For the C lover I am, that seems, errh, HUUUUUGE.

Is it normal?

Note that if I remove the [features=default] argument, mem is divided
by 2, and time by 3. Also note that if I use more faces, it can go to
2Go of ram and 2 minutes of computing.

Thanks for your reply,
-AJ

on larger docs (say 200 pages) we get 10 pages/sec

yes, lua allocates chunks in growing sizes and font tables are large; 
the number is not always reflecting the actual usage

hm, the mk test document never tops that much (i think 400 M at most 
when chinese, arab and zapfino are loaded

maybe there's something wrong with garbage collection on youe machine
