Maybe I'm crazy, but when running java -server, replacing vectors/assoc with arrays/aset slowed my project down from 4000 iterations/second to 100! Similarly, removing multimethods for each instruction and loop/recur to churn through them and replacing with one big fn generated up front resulted in a massive slowdown. I haven't profiled yet, but I plan to do so because I'm so surprised by the results.
