Hi, I want to ask another thing about tile hosting.
I have been using datastore for storing tiles for more than 2 weeks and there is no problem about datastore, but the problem is upload tiles to datastore. Sample tile set is composed of approximately 5500 tiles with 27 MBs. I have tried 2 different methods to load : 1.Method : (take 8 minutes to fetch) I have uploaded all tiles to internet and GAE fetch it from the web. This method is faster than 2.Method but I don't want to do a second work as uploading to the internet before fetching. 2.Method: (take 10 hours to POST) I have uploaded tiles via POST with Curl from my computer but it is very very slow compared to the 1.Method which can be seen above. My question is that is there a way to accelerate the uploading via POST method? Thanks. Alper.
