Re: data structure creation time in cljs
I've just updated benchmark dependencies to reflect latest changes in ClojureScript. Keywords are little slower than before but otherwise there are no big differences.

Re: data structure creation time in cljs
Some good news and some puzzling news. With advanced mode, the various forms of non-literal vector creation clock in around 400msec for 1 million ops on node, which is a 2-to-5x improvement. Now, the puzzling bit: Using time, I get a big fat 0 for certain kinds of operations: (time (dotimes [x 100] (Test. x))) -- big fat 0 Again this is on node, running the script from the command line. There also seems to be some issue with laziness, where some of my big list operations are getting a 0 as well. Is advanced mode somehow optimizing these things away because they don't get used elsewhere in the program? Pretty confusing.

Re: data structure creation time in cljs
If anything is an order of magnitude slower than Clojure it should be considered a bug and be filed as such. We're shooting for w/in 2.5X for all operations. `vector` is slow and can easily be dramatically improved. I suspect there's something up with record creation and it should be looked into. You might want to compare with construction time of a deftype instance, I see little reason why records can't be constructed as quickly. Also what optimization settings are you using?
