Though too early to discuss about PHP 7 as first alpha released just 2 days ago.
Has someone managed to test PHP 7 with Moodle?
Other reason for asking this if the results I manage to get are somewhat coherent with someone else who manage to do the test run with php 7 alpha release.
for me, I am truly impressed, with memory usage and rendering time improvement of up to 30% or more as I have been done testing side by side with PHP 5.6.7 (zend opcache enabled in both cases).
Cron job didnt run fully, in addition to a 500 error after purging cache (which I can expect for being 2 days old version of PHP)
If someone else managed to test, let me know if you have experienced the same improvement as I did.
