Re: Re[2]: Accept() loop in php-fcgi?

Dear Igor,

I am pretty sure that my setup is correct.  To verify my setup, I
limit the php-fcgi children to 1, and I use strace to trace that child
process.  On the other terminal, I setup ab2 to get main.php twice:

ab2 -n 2 http://localhost/main.php

The attached strace file shows that each include file is
open/read/close twice.  Do you think PHP engine actually translates
everything into one unit before the intepretation or it works like a
bash interpreter reading and executing line by line?

Thanks,

Jonathan
