I've now compiled a threaded perl5.8.0 and benchmarked prime-pthread from perlthrtut against parrot: $ time parrot t.imc >1 real 0m1.044s user 0m0.730s sys 0m0.290s $ time ./t.pl>1 real 0m8.574s user 0m8.070s sys 0m0.480s "t.imc" is F<examples/assembly/thr-primes.imc>, but producing primes up to 1000 too. Parrot is built unoptimized and runs the slow bounds-checking core. My system is i386/linux (2.2), Athlon 800, 256 Meg RAM (ulimited to 200 Meg). That's about 8 times faster (parrot doesn't copy all its state, but the test program doesn't have much) but sill dog slow. Starting and joining 1000 threads in parrot takes about 5 secs on my system while doing 1000 pthread_create/pthread_join in C takes only ~ 0.1 sec. Its of course far too early to do benchmarks, but interesting ... > Liz leo
