The patch allow save one read() and one seek() syscall for each request.
On hello.php (<?php echo "Hello world!\n";?>) I got 430 req/sec without
patch and 530 req/sec with patch.
I think this INI directive is not a big cost for ~20% speedup.
The test was done without concurency (ab -n1000 -c1).
Thanks. Dmitry.
