Hi! Thanks for the reply!
My tiff's are from 15M to 10G tiff tiles (about 500M each tile) and depending on the map theres the one 15M tiff or from 2 to 3 of the 500M tiles displayed (I have couple of map apps running on the server). It doesn't seem to matter how big the tiff's are since the performance is the quite the same. I also have the .shx files for my shape's. The server doesn't get very much hit's since it's not an open for public application. I believe the average usage is about 1-10 users at the same time. Hope this helps!

(1 GB ram with large files is not so much) Also, do you have spatial index on your files (.shx) ? Spatial index improve performances a lot. May you tell me the size of your files and how many of them are involved in a single map ? Best Regards, Romolo
