My guess is that communications overhead is slowing things down.
What happens if you set these super low, ideally so there's a
single process handling requests, then see what sort of QPS
numbers you get for your trivial text file.
0.1 req/sec
Note that even if it had performed great then it would not
have been a solution because the real thing the PHP scripts
has significant latency when interacting with external database
so parallelization is a must.
