The costs of sharing Leo Töposted a test program and some results for timing the difference between using shared and unshared PMCs. ... Hopefully the benchmark will get checked into examples/benchmarks as suggested by Luke earlier.
Done now. $ time perl58-th shared_ref.pl
real 0m8.694s
$ time parrot shared_ref.pasm
real 0m0.375s
(Unoptimized parrot build, Athlon 800, pthreads/linux-i686) I hope the code is somehow equivalent.
