[ruby-talk:20093] Hash test performance issue
Hello Rubyists, I've bumped into a performance issue when comparing a hash via an iterator. Included is the profiler output. Question: Why is foo = (bar == @bigHumonguosHash) : apple ? orange Soooo much slower than (almost 100%) foo = (bar.id == @bigHumongousHash.id) : apple ? orange What does ruby do internally when it is asked to compare objects via references (especially huge hashes, tens of thousands of records indexed by strings).. p.s. Notice that I just put into use all the "Ruby ways" which were discussed earlier? ;-) -- Wai-Sun "Squidster" Chia RHCE/Professional Services Linux/Unix/Web Developer
