Hi guys one guy mentions that Pharo en exemplos is a better translation than Pharo por Ejemplo so what is your point of view on that? Stef

(Identity)Dictionary benchmarks
by Max Leske May 21, 2013

May 21, 2013

My coworker performed some interesting benchmarks on the various dictionary types in Pharo. If you look at the attachments you'll see four things: 1. SmallDictionary and SmallIdentityDictionary are totally useless when it comes to performance. Unless their existence is somehow justified by saving space (which might be important for embedded systems) I don't see why we should keep them around. 2. The special Fuel collections for large numbers of elements could be a valuable addition to the basic collections 3. SmallInteger>>identityHash is really slow. Using SmallInteger as keys in IdentityDictionary is significantly slower than using them in a regular Dictionary because the identity check is done via #identityHash (#hash simply answers self). 4. Arrays are cool :) Should I open issues on FogBugz for any of these points? Especially point 3 bothers me because I feel that using a "primitive" type should be fast under all circumstances. You'll find below the benchmark data (collected in 1.4, verified in 2.0) and the code to run it.
