I'm grouping by date a resultset coming from the database, it cointains around 2000 dated objects. It is: myObject groupBy: #date. But turn's out that DateAndTime #= comparison is elegant object-wise but not performance-wise. Because it instantiates several other objects along the way. This is in the milliseconds range, but in the agregate of a couple of thousand of objects, it creates a lot of not-simple-objects (it is, not integers), and maybe because of that it isn't as fast as I'd expect. Did somebody experienced this too? Regards, Esteban A. Maringolo
