<div class="Section1">
<p class="MsoNormal">We have migrated our PHP Mapscript application from Windows
to Linux. Everything appeared to be working well until we starting
drawing maps that did quite a bit of label rendering. We found linux to
be over twice as slow as Windows XP (running MS4W 2.3.1) on the same hardware when
drawing labels. If I turn the labeling off, the map performance exceeds
that of windows. I am using the same TrueType fonts on both
systems. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I have tried a number of different debian based
distributions including: Debian Lenny, Xubuntu and Ubuntu Server with different
versions of PHP Mapscript including 5.0.3, 5.2 and 5.4. All exhibited the
same results. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Has anyone ran into this problem? Is there something significantly
different between the way Windows and Linux process fonts that could explain
this? </p>
<p class="MsoNormal"> </p>
