Please i am working on a project should provide fast compiling of Latex files in silent mode so the user should not see any process and just preview the final pdf file produced and i need it faster than usual i tried to use pdflatex by hidden command line but it was slow which takes 4-5 seconds to preview pdf then i tried to use TeXWorks it was really fast but i can not hide it so any suggestion guys.

  • How come TeXWorks is faster than pdflatex? I assume TeXWorks is just a front-end that calls pdflatex... – lhf Dec 3 '13 at 12:16
  • TeXworks has an "integrated pdf viewer", so to compare you should use pdflatex coupled to a viewer that automatically updates, e.g. via synctex. – Andrew Swann Dec 3 '13 at 12:27
  • Welcome @OSjerick if you have any idea about that i will be grateful – MohamedSayed Dec 3 '13 at 12:40

    Have you considered using \includeonly? – user10274 Dec 3 '13 at 15:51

This problem was tackled successfully on NeXTstep where the TeX process would allow access to a .dvi file after a complete page was written to it via IPC (InterProcess Communication).

This feature seems to now be part of pytex and the TeX Daemon --- one can improve TeX performance by:

  • not loading unnecessary packages
  • selectively processing only a portion of a document using \includeonly if it is large enough to be broken up into included files
  • building your macros efficiently (use font instances if using fontspec is one common source of needless re-processing)
  • only accessing graphics once (save them to a box and re-use them as needed)
  • building a format which pre-loads all of your packages (this was much easier on Textures which had a specific menu feature for it) --- ISTR David Carlisle putting a tool for that up on CTAN.


  • keeping the TeX process in memory and leaving it running as a Daemon -- see pytex http://www.pytex.org/ (note AIUI that this is difficult on Windows since it blocks reading a file from stdin if it's still being written to)

Everything else is pretty straight-forward, but it's that last which would be the big pay-off --- I've been disappointed that TeX's IPC hasn't been seen as needful since modern machines have become so fast.
