Purpose
Rationale
Refactoring comparison data into a lookup datastructure allows for
O(1)time lookups rather thanO(n)searches on repositories with lots of tags.How I tested
Manually through the evaluation of logs, where many logs were not printed and it was noticable the number of iterations in the loops. I did not do a benchmark datapoint though.
How to verify
Run on PSR itself as it has enough tags to cause a slowdown and many irrelevant log entries.
