Saw this amazing talk by Brad Fitzpatrick Profiling & Optimizing in Go / Brad Fitzpatrick - YouTube about profiling Go Code. @ashwin95r would definitely recommend you to see this.
Did some analysis on the directors query which had 992 elements in its result. Got svg images for the CPU and Memory profiles. Will study these tomorrow and see how we can optimize this.
Very good idea to do this @mrjn.
