Wordpress on Openshift, very slow to respond
haproxy, openshift, wordpress
Solution
Openshift suspends and serializes apps without much activity after a given period, and the first time they 'wake' they deserialize and this takes time.
Problem
I've just moved my Wordpress website on OpenShift PAAS ecosystem, on a scalable PHP cartridge. But I immediately noticed the website is really slow to respond - around 3000/4000 milliseconds. BUT, when it starts to respond, the page loading/rendering is absolutely fast. here's the url: http://gabrielebaldassarre.com just to give you a comparison, this static website is hosted on the same AWS Region: http://extras.gabrielebaldassarre.com/tos5-4 For that reason, I pointed this bottleneck to the nameservers I use (from Cloudflare, because of naked CNAME needs), but using a online tester, they seems ok. I wouldn't say that my Wordpress is a vanilla config, but it's not a mammoth, after all. And loading time after response starting is ok. I'm wondering if there is something wrong with HAProxy, or my OpenShift configuration, but I don't know how to check or what to do about. any idea?
