XML in latest betas (MkIV & LMTX)

XML in latest betas (MkIV & LMTX)

[Pablo Rodriguez]

Dear list,

I have just installed latest betas for both MkIV and LMTX.

Compiling exactly the same XML sources (a book on ConTeXt in Spanish),
MkIV needs 40s and LMTX more than 52s.

This is the first time I get such a difference in compilation times.

I’m afraid I can’t be sure that output is the same, since different
spacing gives different page numbers.

I wonder whether this might be an issue.

Many thanks for your help,

Pablo

Hm. Is that the first time you compare a MKIV runs with an LMTX run for 
that document? I assume that you time multiple runs.

On the average LMTX should be faster than MKIV (and definitely not 20% 
slower). I assume it's regular luatex?

Not sure where that comes from. There are no fundamental changes wrr 
spacing.

Hard to say without a MWE that exposes the same

No, it isn’t the first time I compare and I time multiple runs.

Sorry, this was my fault. I thought I was running luatex and it was
luajittex.

MkIV times with luatex are 51.x seconds, which is a tiny bit faster than
LMTX (52.x seconds). But this is perfectly normal.

Font expansion (as reported in
https://mailman.ntg.nl/pipermail/ntg-context/2019/095175.html).

Sorry for the noise,

font expansion is always slower (but i admit that i never use it)
