Thank you, Hans! I am playing with it right now and will try to add a
simple example to the wiki. For the time being, I just want to keep some
sort of statistics around, also to measure performance of my computers
and servers. Since the log file will be read and written to by other
programs as well, I'm keeping it very simple, in a text format, so I
simplify your code a bit, maybe that's a good starting point for others
on the wiki to elaborate.
All best

Ah, you're trying to locate bottlenecks ... you need to register timing
pretty late, like this:
\startluacode
luatex.wrapup (
function()
--
print("saving runtime in foo.txt")
io.savedata("foo.txt",statistics.elapsedtime(lua.getruntime()))
--
local t = {
runtime = statistics.elapsedtime(lua.getruntime()),
mytime = statistics.elapsedtime("foo"),
}
print("saving runtime in foo.lua")
table.save("foo.lua",t)
--
end
)
\stopluacode
\starttext
% it's showtime:
runtime : \cldcontext {
io.loaddata("foo.txt")
}
mytime: \cldcontext {
( table.load("foo.lua") or { } ).mytime
}
% let's waste some time:
\ctxlua{statistics.starttiming("foo")}
\dorecurse{500}{
\glyphxscale\numexpr1000-#1\relax
\samplefile{knuthmath}
\blank
}
\ctxlua{statistics.stoptiming("foo")}
\stoptext
Wikifying a better example probably takes more time than this run,
Hans
