[x] You have run ./mvnw verify and the project builds successfully
[x] Tests pass (./test.sh <username> shows no differences between expected and actual outputs)
[x] All formatting changes by the build are committed
[x] Your launch script is named calculate_average_<username>.sh (make sure to match casing of your GH user name) and is executable
[x] Output matches that of calculate_average_baseline.sh
[x] For new entries, or after substantial changes: When implementing custom hash structures, please point to where you deal with hash collisions (136-142)
Execution time (6-core i5 @ 3.70GHz): Range (min … max): 6.970 s … 8.332 s 10 runs
Execution time (4-core i5 @ 2.40GHz): 9-11s
Execution time of reference implementation: ~3m 4s
Hello, one more improvement from me: city array byte buffer is copied only when new Record instance is created.
(there is also a second improvement - splitting the memory into a more even chunks - but this change will have no effect on a test that is run against 8-core machine)
