Subject: Something smells rotten in the state of luametatex...
Date: Fri, 8 Oct 2021 18:09:38 +0200 [thread overview]
Message-ID: <c247ca4f-ca8d-9dc7-3578-c10764ed4dd6@uni-bonn.de> (raw)
Hi all,
I have a document here for one of my classes: xml processed via context,
some layers, some two column paragraphs, a bibliography, nothing out of
the ordinary. With mkiv, it compiles cleanly:
mkiv lua stats > used engine: luatex version: 1.13, functionality
level: 7420, banner: this is luatex, version 1.13.0 (tex live 2021)
mkiv lua stats > used hash slots: 48846 of 65536 + 250000
mkiv lua stats > lua properties: engine: lua 5.3, used memory: 212 MB,
ctx: 210 MB, max: unknown MB, hash chars: min(64,40), symbol mask: utf (τεχ)
mkiv lua stats > runtime: 2.775 seconds, 119 processed pages, 119
shipped pages, 42.883 pages/second
system | total runtime: 5.996 seconds
When I compile the same document with luametatex, things slow down to a
crawl:
mkiv lua stats > used engine: luametatex version: 2.0921, functionality
level: 20210903, format id: 594, compiler: gcc
mkiv lua stats > tex properties: 740039 hash slots used of 2097152,
48372 control sequences, approximate memory usage: 36 MB
mkiv lua stats > lua properties: engine: lua 5.4, used memory: 100 MB,
ctx: 93 MB, max: 138 MB, symbol mask: utf (τεχ)
mkiv lua stats > runtime: 27.509 seconds, 119 processed pages, 119
shipped pages, 4.326 pages/second
system | total runtime: 139.458 seconds of 139.493 seconds
So, it takes more than 20 times as long... The CPU of my computer goes
up to 100 %, and the entire machine sometimes becomes unresponsive
during the run. Obviously, I can't provide a MWE, but this seems
bizarre. One thing I see on my terminal: there are hundreds of lines
like this
Overfull \hbox (0.8pt too wide) in paragraph at lines 18--18
6:17: [glue][glue]<l2r par><l2r
[glue][boundary][hlist][penalty][glue][hlist][penalty] >[glue][glue]
It's almost like some debug setting has been triggered. But that may be
a red herring. Anyway, I just wanted to report this; maybe some bigger
problem (with the binary or the format?) is lurking somewhere.
All best
Thomas
