# [XeTeX] xetex memory usage

Tue Dec 16 20:53:59 CET 2008

Hello,

I'm using MiKTeX 2.7 and xetex(xelatex) integrated in it. OS: Windows XP
SP3.

My question is about memory usage of xetex. I've noticed that when I
compile tex document, though this:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Arial}
\begin{document}
The quick brown fox jumps over the lazy dog.
\textbf{The quick brown fox jumps over the lazy dog.}
\emph{The quick brown fox jumps over the lazy dog.}
\end{document}

I see that it uses at least 130MB of RAM to generate pdf. So if for
example I'm going to use xetex to generate pdf reports via webpage it
can cause memory overusage. For example if 10 people start to generate
pdfs simultaneously then 1300Mb of RAM will be used and it can cause the
problems. We run into this problem already (with much more complex tex
documents) and server with 512 MB of RAM and it was overloaded.

So my questions are the following:

1. Is this problem related with xetex or maybe fonts loading into
memory? If it is not related to xetex then sorry, I'll try to find
