phoronix-test-suite waits for an http timeout every time the command is run - even if it is being asked to simply list its help text. On my system the error is:

Warning: file_get_contents( failed to open stream: Connection timed out in /home/duanev/phoronix-test-suite/pts-core/library/pts-functions_basic.php on line 136

This may be a configuration error of some kind but it is unacceptable for a locally installed test suite command or utility to attempt to contact the network every single time it is used. Please redesign this aspect of the suite and use an imperfect network when testing the suite to catch these kinds of problems.

Most of the 127 tests have downloaded so I've no idea what why the above occurs every time.
