Some additional questions. You wrote about tiles, so you are talking about raster/image data ?
Where are your tiles stored. On a shared drive or in a database ? if you use a database, which one ? Are your tiles multiband images or images with a color table. If you are unsure, send me the output of gdalinfo yourtile.png. I achieved a performance boost when switching from multiband images to images with a color table.
