[mapserver-dev] mapserver performance windows/linux

Hi Dan,

 

Its executing the same code on Windows and Linux.   I assume that would
be the same.

Are you using the same label rendering engine on both platforms (GD
True-type or AGG)?

	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.  

	 

	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.  

	 

	Has anyone ran into this problem?  Is there something
significantly different between the way Windows and Linux process fonts
that could explain this?  

	 

	Thanks, 

	Chris
