I have a VPS running Apache (prefork mpm) with 1gb RAM and 2 x Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz.
I setup 2 test files to run through Apache Benchmark: htmltest.html (basic HTML file which just displays some text) phptest.php (a completely blank php file)
I ran the following Apache Benchmark command for each: ab -k -n 1000 -c 70 THE-TEST-URL
The results were:

Something has to be wrong here because the HTML file took only 5 seconds to complete the test and the blank PHP file took a whole 2 minutes to do the exact same test.
Is there a specific config file I should be looking at to fix the problem here?
