* Exit earlier from loop when a new Result is created (#668)tivrfoa2024-02-011-200/+127
| | | | | | | | | | | | | | | | | * 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.

* serkan-ozal's 7th submission: (#679)Serkan ÖZAL2024-01-312-40/+43
| | | | | - use smaller regions (increased region count) so there will be less idle time for the workers who completed their tasks - get rid of some configuration related stuff during initialization which might save a few tens of milliseconds hopefully - update temperature value parsing instruction order to get benefit of ILP better (hopefully)

* batched writing to disk (#659)nicky2024-01-311-5/+8
| | | instead of writing result line by line, implemented random.choices for randomisation of multiple stations and writing large batche ot the disk, also instead of "round" just using :.1f which is probably quicker on a large scale, because it's not a mathematical function
