I've done some major changes in my document (dissertation, nearly 300 pages) and now compiling time has increased nearly by factor 3!
One pdflatex run took normally less than 3 minutes before and now takes about 6 minutes, for complete compiling with latexmk it took 26 minutes!!!
What I've changed:
- switched all source files (.tex and .bib) to UTF8
- had to switch from bibtex/biblatex to biber/biblatex
My questions:
- Can the change to UTF8 slow down compiling?
- I read about some problems with kpathsea checking deeps directory paths during each compiling. How can I find out if I have such a problem?
I formerly had 2 TeXLive distros on my machine, but currently only have TeXLive 2014 installed.
Hard and Software
- MacBook 13" (2007)
- MacOS X 10.6.8
- TeXLive 2014
- Aquamacs 2.5 as editor
- compiling is currently done from command line (pdflatex or latexmk)
Further investigations of the suspects:
1. TEXINPUTS
the command kpsexpand \$TEXINPUTS
gives the following result:
(added linebreaks after each path)
.:{/Users/mbg4/Library/texlive/2014/texmf-config,
/Users/mbg4/Library/texlive/2014/texmf-var,

The directory /Users/mbg4/Library/texmf does not exist. However, there is a directory /Users/mbg4/Libary/texlive

2. Tikz/PGFplots
-
I don't use tikz in my document, however I did one experiment with tikz and found that I still have the following line in my preamble:
%\usepackage{tikz} %Graphiken mit TikZ/PGF -> http://www.ifi.uio.no/it/latex-links/pgfmanual.pdf
It's commented out, so I think it should have no impact at all, but I still try to remove it.
- But: I use IPE 7 for creating my graphics and had tried to embed a tikz tree in an IPE document. I removed the tikz tree, but I forgot to remove the usepackage commands in the IPE latex preamble of this document. And the resulting PDF (created with IPE) is used via
includegraphics
in my pdflatex document. So I'll see if it helps removing the tikz code from there.
3. Datatool
- I don't use datatool, at least I'm not aware of it and a grep -ir datatool …
4. Unicode
not yet investigated
5. biber
-
biber seems to have a large impact. I use this biblatex setup currently:
\usepackage[natbib=true, style=numeric-comp, backend=biber, defernumbers,useprefix,firstinits=true, maxnames=99, maxcitenames=3]{biblatex}
and as soon as I replace backend=biber
to "backend=bibtex8`, the compiling time was reduced dramatically (from nearly 5 minutes for 98 pages to 37 seconds – only 1 pdflatex run).
Switching back to biber
, I get a compiling time of 2min40sec – I'm quite confused, maybe some cache issues?
to be continued here: Why does biber increase compilation time of pdflatex runs dramatically (factor 2.8!!)?
Remarks:
- I know that this is very little information at the moment and I'll do some more tests to find the problem, but some general suggestions and comments how to approach that problem would help me very much!
- I'm using version control and I'll try to go back to the original state before the compiling time went up and try to compare the outputs.
Best Answer
It seems that using
backend=biber
is causing the amazing slow down,I've asked a new focused question here to discuss this issue: Why does biber increase compilation time of pdflatex runs dramatically (factor 2.8!!)?
