Tiled image tiles stop loading #113

Closed mzur closed 5 years ago

mzur commented 5 years ago

Bank said that the image tiles of their huge mosaics stop loading after a while. I couldn't reproduce this yet so I asked him for more information.

The problem is this: The image is initially loaded into the tile cache. The cache can easily get larger than the soft limit of 1 GB with only two or even one huge image in the cache. Each minute, the cache is pruned and the tiles removed. But users spend more than one minute with one tiled image and experience just the problem described above.

There is no easy fix for this. Increase the soft limit of the tile cache size? Or increase the interval the cache is pruned? Both?

I increased the soft limit for the tile cache size to 5 GB. This should be enough to store a few of the huge tiled images.
