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:

When I compile the same document with luametatex, things slow down to a
crawl:

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.
no, that's just a more verbose 'overfull box' message ... does adding
\dontcomplain help? (After all you can live with .8pt which smells like
2 * .4pt which is the default rule width so maybe some frame stricks out)
