I am not impressed by Apache + mod_php performance on VMS.

 I recall that Apache offers a choice of worker processes or worker
threads. I suspect mod_php is not thread-safe, so you have to use multiple
worker processes. And process creation on VMS is expensive.

Apache on VMS starts multiple processes. But they should
be reusable (otherwise it would be CGI reimplemented). The
client test app use 20 threads, so Apache should
only need to start 20 child processes and let them
process requests. So even though process creation indeed
is expensive on VMS, then it should not kill performance
like what I see.
