mapcache file system

For caches use btrfs file system. Have best experiences with it instead of using
ext3 or ext4.

you can use a “templated” disk cache
/path/to/tiles/{tileset}/{grid}/{z}/{x}/{y}.png
note however that unless you are seeding small caches, you will very
rapidly hit the maximum number of files allowed per directory by your
filesystem.

openlayers scales to resolutions
https://github.com/openlayers/ol3/issues/757
I got the resolutions, simply by running it in my OL2 example and calling
scales=[10000, 25000, 50000, 100000, 250000, 500000, 1000000, 2000000, 4000000,
8000000];
ress=[];
for (var i = -1, leni = scales.length; ++i < leni;) {
ress[i]=OpenLayers.Util.getResolutionFromScale(scales[i],'m');
}
ress;
in the Chrome dev tools.
