Hello,
I wonder -- why wait up to 5sec to (re)compile a single page on a Core 2
Duo machine?
Let's look at the end of the log file for my simple, one-page document:
mkiv lua stats : input load time - 0.000 seconds
mkiv lua stats : stored bytecode data - 184 modules, 45 tables, 229 chunks
mkiv lua stats : node list callback tasks - 4 unique tasks, 3 created,
75 calls
mkiv lua stats : cleaned up reserved nodes - 23 nodes, 9 lists of 1410
mkiv lua stats : node memory usage - 20 glue_spec, 2 dir
mkiv lua stats : used backend - pdf (backend for directly generating pdf
output)
mkiv lua stats : loaded patterns - en:us:pat:exc:2
mkiv lua stats : startup time - 0.531 seconds (including runtime option
file processing)
mkiv lua stats : callbacks - direct: 288, indirect: 3681, total: 3969
mkiv lua stats : loaded fonts - 37 files: lmmono10-regular.otf
lmmono12-regular.otf lmmono8-regular.otf lmmono9-regular.otf
lmroman10-bold.otf lmroman10-regular.otf lmroman12-bold.otf
lmroman12-regular.otf lmroman7-bold.otf lmroman7-regular.otf
lmroman9-bold.otf lmroman9-regular.otf lmsans10-regular.otf
lmsans12-regular.otf lmsans8-regular.otf lmsans9-regular.otf eufb10.tfm
eufb7.tfm eufm10.tfm eufm7.tfm msam10.tfm msam7.tfm msbm10.tfm msbm7.tfm
lmex10.tfm lmmi10.tfm lmmi12.tfm lmmi7.tfm lmmi9.tfm lmmib10.tfm
lmmib7.tfm lmsy10.tfm lmsy7.tfm lmsy9.tfm minionpro-bold.otf
minionpro-it.otf minionpro-regular.otf
mkiv lua stats : fonts load time - 2.750 seconds
mkiv lua stats : result saved in file - garden_in_the_rain.pdf
mkiv lua stats : luatex banner - this is luatex, version
beta-0.43.0-2009083017
mkiv lua stats : control sequences - 29475 of 165536
mkiv lua stats : current memory usage - 147 MB (ctx: 151 MB)
mkiv lua stats : runtime - 3.438 seconds, 1 processed pages, 1 shipped
pages, 0.291 pages/second
Startup time is 0.531 seconds. OK. Then, why on the Earth all these
lmxxx fonts are loaded, if I use Minion Pro typescript? 2.7sec... Hmmm.
Seems like a root of evil. What can I do to get rid of all of them?
My typescript:
\starttypescript [serif] [MinionPro]
\definefontsynonym [Serif][MinionPro-Regular.otf][features=default]
\definefontsynonym [SerifBold][MinionPro-Bold.otf][features=default]
\definefontsynonym [SerifItalic][MinionPro-It.otf][features=default]
\definefontsynonym [SerifBoldItalic][MinionPro-BoldIt.otf][features=default]
\stoptypescript
\starttypescript [MinionPro]
\definetypeface [MinionPro][rm][serif][MinionPro][default]
\stoptypescript
Regards,
Vyatcheslav

those fonts are loaded for math (and only once as fonts are shared)

this takes 2.5 seconds on my machine
\starttext
\usetypescript[palatino] \setupbodyfont[palatino] test\par
\usetypescript[postscript] \setupbodyfont[postscript] test\par
\usetypescript[cambria] \setupbodyfont[cambria] test\par
\stoptext
(there is a way to prevent initial loading but it does not save that
much time)
two cores is less important than a big 2 level cache (influences lua
runtime) and memory (so that files are cached in mem)

if you run from the console (cmd), then consider switching to 'console2'
which is faster wrt refresh (windows consoles have a high refresh rate)

one still would need to initialize .. and in most cases docs are more
than one page

Hi,
1)

Don't understand what 'shared' fonts mean, but how can I prevent these
math fonts from loading? Maybe elaborate the typescript?
2)

Mine is 2.656sec, but actual time is > 5 sec (I had a lot of complaints
about math issues like
'math virtual | unicode point U+1D6EB has no index 004B in vector tex-mi
for font rtxmi' )
3)
Would it be reasonable to have ConTeXt as a service sitting in the
memory and processing documents on demand?
I believe that >2sec for processing a single page plain text document is
ridiculous. Given modern computer power, I suppose it can be done
instantly. (Or am I are mistaken?)
