We'd be very interested in this. I've often wondered how much overhead there was in continually loading and unloading modules

Based on my studies and profiling, it seems to be relatively consistent at approx 2-3 seconds, in 1.3, per page load.

Interestingly if I just try to run as is under Starlet performance goes through the floor (6 sec + per pageload). but if I pre-load the expensive modules in my .psgi file, it goes down to under a second in 1.4 (should be similar under 1.3).  There is probably room for more tuning than this but this is where I have gotten so far.
