Exit earlier from loop when a new Result is created ( #668 )
...
* Exit earlier from loop when a new Result is created
* 3) Make a cache of long[] name to String, to avoid `ByteBuffer.allocate`
* and creating new UTF-8 strings. I didn't profile, so it's just a guess
* that this map will be a bit faster. Although it's outside the main loop, so
* not a big difference ...;
* 4) Exit earlier from loop if a new entry was created.
* revert: Remove cache to city name
* As I was not able to make it faster... make it slower
As I was not able to make it faster ... so I'll make it slower,
because my current solution should *not* stay at the top, as it added
basically nothing.
