Summary Increase disk cache capacity when there is lots of free space

Our maximum disk cache capacity has been 175MB for very long time. Meanwhile the average resource size has grown massively. This is enough for cacheable resources of a few dozen sites at most. By using bigger caches when there is room for it can save battery and speed up page loading.

Comment on attachment 280804 [details] patch View in context: https://bugs.webkit.org/attachment.cgi?id=280804&action=review > Source/WebKit2/ChangeLog:15 > + >=16GB free: 175MB -> 500MB > + 8-16GB free: 150MB -> 250MB Perhaps the heuristic should take into account the percentage of free space, not just the amount. At some point, it was recommended that no more than 75% of SSD should be used (http://www.anandtech.com/show/6489/playing-with-op). I don't have newer references, but I believe that consumer grade SSDs still work the same way.
