Every time Clojure comes up I can rely on you to appear and attack something about it (but never the core merits of the language, as far as I can recall.)
The time you are reporting is also not that 'fast'. Other tools start in a fraction of that time.
Edit: original comment mentioned sbcl and included sbcl repl start-up time.
'less slowest starting Clojure REPL of three'
Mentioning 'fastest' at a time of 3GHZ multicore machines with SSD and a duration of 0.1 seconds is just absurd. That's >100 million instructions just to start a language prompt and evaluating a symbol to itself. The Java version is even more absurd with around 1 billion instructions just to get a REPL...
A shell on a 1 MIPS DEC VAX 11/780 started faster, while the machine had a hundred users.
