# Too much time spent in compilation [closed]

I have created my thesis and I have a problem enough annoying. I have created the appendix of my thesis and put into all tables. I used as font mathptmx. When I try to compile it takes so much time about 40 minute. This is a part of my main file:

...

\usepackage{mathptmx}

...

\begin{document}
\input{appendix}
\end{document}


When I comment that line or use another font, I got a fast compilation. I don't know the reason. The problem is I can't post all the appendix because there are too many table. What do you suggest to solve the problem?I have to use mathptmx so I can't change font

This is going to be hard to help with without seeing some form of example. Could you give a short demo of one of the tables? –  Joseph Wright Jan 15 at 19:08
Yes sure I can give you an example... –  Mazzy Jan 15 at 19:12
Well, there are lots of errors flagged up! Wild guess: does your appendix contain lots of tables typeset using siunitx? If so, take a look at the 'speeding things up' section in the siunitx manual. –  Joseph Wright Jan 15 at 19:43
Opps, misread some pdfTeX info. The section in the siunitx manual is 7.9, 'Maximising Performance', p. 69 in current release. –  Joseph Wright Jan 15 at 19:57
A comparison with a log file with a different font might be helpful. Btw, are these nullfont warnings expected? –  mafp Jan 15 at 21:24
