disable tiered compilation for benchmark runs
disable tiered compilation for benchmark runs

by default, leiningen sets the JVM up for startup time, via tiered
compilation (see https://github.com/technomancy/leiningen/wiki/Faster).
This doesn't play properly with benchmarks, because it disables the more
aggressive JIT optimizations, which can (but don't always) have a severe
impact on benchmark results. You have to use `^:replace` on `:jvm-opts` to
accomplish this.
