Magento 1.7 performance seems abnormally slow on WebFaction 512MB. (Nginx + PHP-FPM)

Question

I'm trying to move a Magento 1.7 site to a WebFaction 512MB plan. Currently it's on a several-GB Linode (and it absolutely rocks), but we have to move it onto our own server now and I'm having trouble getting it to perform well (typical page load is anywhere from 45s to several minutes, often timing out at 5 mins).

As mentioned in the title, I'm running Nginx with fastcgi_pass to the PHP-FPM socket (php 5.5.0, w/zend opcode). FWIW, I've already moved our Wordpress site to this server, and it's performing great under basically the same setup. I've also got a similar setup running on my local VM, similar PHP settings, and it doesn't have any trouble delivering a page in 3-5s. I've done lots of profiling with XDebug, and I'm still at a loss - it says that about 90% of the time is spent in spl_autoload (handled by lib/Varien/Autoload), but I don't know if there's anything I can actually do about that. I've echoed get_include_path() and it doesn't include anything weird, so... I just don't know.

Here's some relevant config info, at pastebin:

• Nginx config
• php-fpm.conf
• php.ini

I'm at my wits end, and am basically hoping for at the very least, a simple sanity check: Magento on Webfaction, 512MB, PHP Fastcgi - is that crazy? Not sure if it matters, but we've only got like 75 products. Let me know if there's other info that might help, I've got the php "slow logs", xdebug... yeah. I'm just unable to see the problem at this point, but I feel like I've got the tools to ferret it out, whatever it might be. Thanks in advance!

Answer 1

I'm afraid that this will come down to the underpowered environment. Correct me if I am wrong but your hosting is probably a VPS and sometimes, no matter how much optimisation you do - it's often easier to upgrade the hosting.

Answer 2

I'm at a loss why you would move from a VPS to a shared hosting provider like Webfaction. If you bought a dedicated webfaction server why are you limited to only 512mb?

Answer 3

The problem was not with my app or my nginx/php settings at all, it turns out the server my account is on was totally overloaded and has since been dealt with. My app now loads really fast, basically as you would expect.
