Will Drupal & Drupal Commerce run under php-cgi? For some specific reasons (experimental setup - not Apache nor nginx) want run Drupal  under php-cgi (not fast-cgi). The site should serve an very-small e-commerce site - probably Drupal Commerce. 

Based on my googling Drupal can run under php-cgi, but the found links are pretty old (2009 and such),  so looking for some answers for both of current main versions - for the v7 and for the upcoming v8.

The questions are:


Will Drupal (v7 and/or v8) run under php-cgi?
Will run Drupal Commerce under php-cgi?
are here some major limitations (other than speed!) caused using Drupal (and Drupal Commerce) with php-cgi?
Core in particular, but also Commerce, is extensively covered by automated tests. 

Many of those are also run in a style that simulates a users journey, not only unit tests. So if you run those, you will have exercised essentially all relevant code.

There are some things that are not covered though, such as CSS and JS, although I strongly doubt those are affected by how you run the php interpreter.

Setup a Drupal instance, enable the testing module, and execute all the tests. Go read a book (as that will take a long time), and hope that you come back to all green. :)
