Benchmarks: Dictionary vs. Object vs. Array vs. LookupList

[Update: I put the code of the LookupList class at the bottom of the article] [BIG Update: there was an error in the LookupList class -> now it’s much slower than the rest] And another benchmark comparing various ways of getting an object for a key that is stored in a table. The key is […]
