[mapguide-users] Raster - best practices

[Stefan Dalakov]

Hi all,
I have read in "Best Practices Wiki " about optimizing raster 
performance, where it is advised to create an alias for raster files. I 
have raster datasources, but instead of setting an alias I have used in  
my configuration files portion like this :
 <Location name="C:\Rakvag\">
 <Feature name="rakvag_join.tif">
 <Band name="RGB" number="1">
 <Image frame="1" name="rakvag_join.tif">
and it works.
So the question is : Does it make any performance difference and if yes, 
how should the configuration file look like?
And another question :
About image pyramids - I am using tiff files. Is it better for 
performance to have all previews in a single file with several image 
frames or have them separated into different files

Thanks in advance : Stefan Dalakov
