Nor Facebook's. I can't give away numbers, but the fraction of
cycles per total memory allocated averaged over all of
Facebook's PHP programs (PHP being reference counted) is
staggering. Staggering!
If PHP didn't follow a stateless request model (which allows
us to use region allocation and reclaim all memory upon the
request's end), we'd be literally unable to run a server for
more than a few minutes.
Don't remind me. About 8 years ago I had to abandon a big PHP
project simply because PHP couldn't deal with cycles. There was
no way to scale the thing.
