I am using TileCache to load WMS layers which contain quite long labels. As

metaBuffer set to a high enough value to solve this. To get around the slow
initial loading times, i also run a seeding script which pre-caches all the
tiles in question.
I am now experiencing very slow loading times (compared with direct access
to MapServer) even after seeding, and terrible lag panning the map in a
circle with either of these layers activated. I had believed that once all
the tiles were seeded that these requests would be simple http image
requests but instead it seems as though the metaTiling is requested time and
Are there any other settings i can tinker with to gain better performance
with metaTile? Am i missing something important here?
I sincerely hope anyone can shed some light on the situation as i am at a
A snippet of my tilecache.cfg is as follows:
My seeding script is as follows
rainfall_stations 0 8 110.0,-45.0,156.0,-8.0
dwo_sites_open_closed 0 8 110.0,-45.0,156.0,-8.0
