Performance optimization for tiles downloading #492

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Use an online tilesource for the first time, with no tiles cached
2. Fetching of the tiles will perform badly on a 3G network
3.

What is the expected output? What do you see instead?
A better performance.

What version of the product are you using? On what operating system?
3.0.10

Please provide any additional information below.
Is there a chance to implement some performance optimizations for the tiles 
downloading?

How do you expect to achieve this?

Would it maybe help if you integrated Volley or something similar, and then, 
when the new tile request comes - immediately cancel all the download requests 
for the tiles that are not visible on the map?
