23837	Investigate setting `-XX:MaxRAMPercentage` to >25% of system memory	taylor.smock	team	"The flag was added during the Java 8 update cycle (but not as part of the initial Java 8 release).

The default is 25% of system memory; we can probably safely use up to 75% of system memory.

We may also want to look into setting the minimum memory (`Xms`) to something semi-sane.

Possible minimums for `Xms`:
* `99mb`: Clean JOSM install after starting
* `136mb`: JOSM with ''minimal'' amount of data loaded (1129 nodes, 414 ways, 13 relations)
* `161mb`: JOSM with ''minimal'' amount of data loaded + background layer
I'd probably round up to the nearest power of 2 though, so `128mb` or `256mb`."	task	closed	normal	24.09	Core		fixed		sebastic
