Hello, here some things that running absolutely not smooth in my eyes and we should work on this problems:
*The Expiring/updating process is not running for months.[1] (To have an up-to-date map is perhaps not so important for wikipedia, but I hear from some mappers, who use hikebikemap and other maps to control there changes.)
*The rendering of the >200 styles for the different languages make it difficult to handle the server.
*We have running now a productive system and experimental systems on the same server. This means we can't make in the moment big experiments! I will be also in Berlin and I hope we can talk about a solution for this situation.
*We have enough CPU power but if I look on the I/O-power [2] it looks that we are on the end of sd3-reading power. So I'm not sure about the reason, but I don't believe that we should activate gadget in en.wp in this situation. (A upgrade to SSD's would be very interesting for I/O-power. I my eyes we would need only 400 GB so it shouldn't cost too much if we could speed-up the rendering perhaps by factor 5! This would also speed-up the other tools which uses the OSM-database. A solution by brain-power would be off course better.)
*We have a performance problem for "full-styles" at medium zoom-levels so e.g. "black-and-white"-styles running in the moment at zoom-level 10 over 1000 seconds for one meta-tile. That's too long!
So in this moment it wouldn't be a good idea to make advertisement for new developer to bring more and more map-styles on the server.
With activating the map in english wikipedia I estimate that we could increase the load on server by factor two. If we make advertisement for this map the peak on the first day could be higher.
So we have a lot to do, especially in the admin area. And we should talk more about this problems on this list. --------- To the legal concerns I give Frederik an answer on legal-talk[3]. That shouldn't be our biggest problem.
Greetings Kolossos
