slow compilation?

slow compilation?

[Pablo Rodríguez]

Dear list,

although I cannot find it now, I sent a message to the list describing
that I suspected ConTeXt wasn’t as fast as it should on my computer.

Here you have a minimal sample:

    \starttext
    \input knuth
    \stoptext

It takes about 3.5 seconds total runtime to compile. Is this the
standard required time?

Actually what I wonder is why the compilation requires three runs to
output the final document.

Many thanks for your help,


Pablo

Your minimal example takes for me on the first 1.8 (terminal) to 2 seconds (editor)
and each consecutive run about 0.6 seconds.

When you process a new document the first time context takes three runs
to store and read data in the temp files (references and roc etc. values).

After this context takes in most cases only a single run unless references
have changed (e.g. the reference is now on a new page) or new entries
are written to the temp files (e.g. when you add a additional heading).

\starttext
     \dorecurse{1000}{test\page}
\stoptext

does 540 pages per second

of course in practice it all depends on what features are used but 3.5 
seconds is way off, unless you remake the format each run (coul dbe the 
case of your luatex doesn't match texlua

Many thanks for your reply, Wolfgang.

So if I need three times for each compilation (since I use --purgeall),
the time is fine, since my laptop is already some years old.

Many thanks for the reply, Hans.

My system does 172.980 pages/second in the last run. My laptop is way
older than yours (Genuine Intel(R) CPU T2050  @ 1.60GHz / 2GB RAM /
Fedora 19).

Out of curiosity, why do you use --purgeall? ConTeXt only generates two 
auxillary files (.tuc and .log), so it is does not really clutter the 
current working directory (unlike LaTeX which generates some 10 different 
aux files).

I thought ConTeXt could generate more auxiliary files than two.

And using --purgeall I don’t have to remember to delete auxiliary files
when the document is finished.

But I guess I‘ll use --purgeall only when the document is finished.

In MkII ConTeXt used to generate more auxiliary files; in MkIV it only 
generates one (.tuc). The log file is a TeX feature that cannot be turned 
off (I think).

If you use bibtex, then ConTeXt must also generate the .aux file (because 
that is hardwired into bibtex!) and bibtex then generates a bbl file. So, 
in the worst case, you end up with four extra files.

or just --purge as it will keep the tuc file
