Yes, since different "nodes" (Actually the right word, would be 
T at Hclients) are using different computers, with different specs. If your 
request is rendered by someone using a P3 700 Mhz machine, it will be 
rendered slower, than if it is rendered by T at Hclient on a Core Quad 2.6 
Ghz processor.


I.E. I'm running 2 Dual-CPU P3 1Ghz boxes, and occasionally have the 
laptop (1 Ghz P3 mobile) running as well. The Dual cpu boxes are running 
6 clients each, and the laptop anywhere between 3 and 6, depending on 
what I'm doing on the laptop at the moment. A tile can take anywhere 
between 2 minutes to 45 minutes to render the two layers done by the 
client, depending on content in that tile.

There will be a speeded up T at H client committed to SVN in the next 
couple of days, which will cut down the time for the sea/land tiles, and 
I'm also thinking that my personal hack for uploading each layer when 
they are finished will be included. That way you'll have the updated map 
layer available faster, while the updated maplint layer will be 
available a bit later.
