Interesting results trying to optimise a website for a client.
This is the blitz.io results before and after.
In both cases the website run the same Lemonstand installation.
The before setup had a standard cPanel installation with:
PHP 5.4.21 with XCache
The after setup has:
PHP 5.5.15 with Zend OPcache (running as php-fpm)
There is obviously a lot of difference between the two setups.
In the original setup the cPanel setup made it very hard to optimise the server.
The new setup makes better use of the available vCPUs and allow a lot of fine-grain tweaking (e.g available connections).
It has a lot more memory but it but barely seems to touch it – most likely thanks to nginx’s low footprint.
Still needs a bit of work (getting the odd 502 Bad Gateway now and then) but that’s pretty impressive.
