Hi all, just my $0.02 here 100 processes per second is not all that impressive for a Catalyst app. I have tested Catalyst in mod_perl with mod_worker (multi-threaded apache/perl), in Linux 2.6 and FreeBSD 6.4, 7.x
With mod_worker, you can spawn processes each with an X number of threads each. Memory sharing in mod_worker/mod_perl is good and you can play with the amount of requests each process can handle before it is killed and restarted, this way you don't have to worry about leaky modules/code. In general, I have used relatively simple applications and others that use FormBuilder, and even some XS modules from Catalyst such as XML::LibXML, and in general the leaking is pretty decent, but againg not to worry (see above). Compiling Apache and mod_perl for threads is not that hard, and there are many variables you can play with in the Apache conf. Anyway, the message is that with mod_worker/mod_perl you can spawn _thousands_ of threads, getting impressive concurrency (without counting the mutex). We have tested Catalyst applications that handle _thousands_ of concurrent requests using off the shelf AMD 64Bit HW and 12Gb RAM, with a Catalyst app of about 20MB RSS.
