What are you thoughts on PHP 7 performance. I have seen the benchmarks on Cloudways platform (https://www.cloudways.com/en/php-cloud-hosting.php ). It was tested with wordpress and the result was 37,378 hits with 0 errors and 0 timeouts. Average response time was an impressive 4ms on vanilla WordPress 4.4 with caching. I believe it is amazing and people should update to this version.
