[OpenLayers-Users] OpenLayers.Layer.TMS requesting too manytiles?

[Eirik Wahl]

Just an extra tip for anyone experiencing trouble with
TileCache/mod_python:

We had a similar problem with TileCache, and couldn't get mod_python to
work on our Windows server.

We switched to geoCache [1], which basically is a port of TileCache from
Python to C#, and this works very well for us and our Windows
IIS-server. It integrates very well with OpenLayers.

Eirik

Chris,

I converted to mod_python, I see what you mean from the performance end.
Thanks for your help.

1. Don't use TileCache as CGI if you care in the slightest about
performance. Really. I mean it.

2. set 'buffer': 0 as an option on your TMS layer.
