FYI, I had to visit those parameters for my PS3 port and cut down on the bombastic memory footprint of 2.7 dicts. Some the supposedly tunable parameters aren´t tunable at all. See http://blog.ccpgames.com/kristjan/2012/04/25/optimizing-the-dict/ Speed and memory are most often conflicting requirements. I would like to two or more compile time settings to choose from: Memory optimal, speed optimal, (and mix).
