Slow Layer Display

[Ethan Alpert]

Check out generating a spatial index (.qix) for your shapefile using
shptree. This will speed up displaying when zoomed in to a subset.

Also check out MAXSCALE and MINSCALE to make sure you're only displaying
the shapefile when it makes sense. With such a large number of records
does it make sense to always display the layer?

Hello Everyone,
iam a newbie to mapserver and this is my
first post.i have an elevation data shape file which has as many as
4344711 records in the .dbf file.This shape file is taking  7--8 mins to
get completely displayed on the browser.

iam assuming that delay in display time is due to the large numebr of
records in the .dbf file.

is there a way to speed up the process of displaying the shapefile. iam
using PHP and html.

All your suggestions are welcome

Regards
Arun
