[mapserver-users] testing mapserver largefiles rendering improvements

[Burgholzer,Robert]

If there is zero overhead to check for the existence of a ".qix" file
and determine if it is up to date, I think this is a good default (no
magic required).  

As for making it work out of the box for the typical user who is not
interested in the nitty-gritty: Perhaps the "quick install" documents
could say "Step X: Run the shptree on all your shape files".

I'm not sure that "standard" user uses often msDebug().
My point was just to say that if somebody tries and tests MapServer, 
he/she will only read the basic documentation to have a working mapfile 
on a dataset. Once it works, no more reading will be done. And if a 
large shape is tested, the user can then be disappointed.
The thing is that it's more than a specific tuning stuff, maybe more 
than a GIST index on a postGIS database.
I think it should be mentionned at least in the Vector Data Access / 
shapefiles doc of the website. In addition to "Shapefiles are made up of

a minimum of three similarly named files, with different suffixes..", 
one could write : "having a .qix file made with shptree improves 
considerabily the performances, mostly on large shapefiles"

Beside this, I like the idea of building a MapFile Optimizer too... 
Daniel, what do you have in mind exactly ?
