I don't know the actually connection limit but as long you use your own script to connect my u_kolossos database you shouldn't effect my connection limit. If it runs good a query need in the moment 0.02-0.2 sec so we shouldn't get a problem that we get more requests than we can handle. One problem in the past was the necessary JOIN for the smaller languages. Off course, we should have a system to stabilize ptolemy especially if more and more maps are coming.

I hear that cassini was running in the last time with a loadlevel of 29 or so and was near to death... Especially prerendering of tiles seems a critical thing, but also looking for and updating of dirty-tiles in low zoom levels seems critical. Also on the FOSSGIS-Tools-Server it seems not easy to find the perfect balance between all tools. In my eyes it could help to have a connection limit for each map style to stabilize the system. But also my Wikipedia-coordinates and especially Query-to-map-project should have a connection-limit and a time-out so that I don't kill all other tools. We should compare the benefit and the costs of each project on this server and set than a specific connection level. For this we need an overview over existing projects. What are the costs we accept for one tile? So I'm absolutly no expert for things like that but we should look at it. Some effects will be well known from normal toolserver some effect will be specific for maps-toolserver. Greetings Kolossos River Tarnell schrieb:
