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.
