Interpreting pageload results - very slow!
My vBulletin based site (running on IIS) is very slow and I need some help interpreting the pageload results. Here are the results:
http://www.webpagetest.org/result/140603_DX_KRZ/ The time to first byte is very slow. Is this a server issue? I just switched the site over to a dedicated server and I thought it would speed things up. But it is even slower now. Also, the cron.php seems to be the next bottle neck. I don't know anything about php code, so any help here is greatly appreciated. |

Did you configure and tweak the server? You need to tweak your my.cnf, php.ini, etc..
What do your server logs say? What cron task is using so much of your servers resources? |

Fully 50% of your pageload is custom font files. Most browsers ignore the fancy fonts and display their set default, but the files still download to the registry. Most visitors will never see them, they're not worth the bandwidth they consume. And most especially, not worth nearly half of your page size in kilobytes.
Try the same test using vB default style, with all hooks off and observe the difference it makes. First Byte Time will be better as well. You are loading more than one megabyte on browsers. Not as bad as many I've seen, but still a bit fat nonetheless. Show me a fat page and I'll show you a slow page, every time. Also, we have a Optimization Workshop Here with plenty of real-life case studies of problems such as this, solved. I use WPT with IE10, exclusively for the full picture: http://www.webpagetest.org/result/140604_JM_RW8/ <--- The CMS The forum is a little more raunchy for pageload: http://www.webpagetest.org/result/140604_RW_S3B/ |

You want to use something like OpenSans from google's font api, which means that there is a very good chance that the user already has this document in their browser cache. Its also fairly tiny. |

If font files are 2% of the pageload or less, it's not a issue. This is 50. That's half. |

In regards to this slow down we really do not have enough information to troubleshoot this. Is it slow all the time or just when a certain cron task is running? Has anything else been changed besides moving it from one server to another? If he is on a new dedicated server though and he just moved his site over from another one then my opinion would be the server or something related to the move. If it was a plug in or theme it would most likely would have happened on the other server as well. Many people grab a root server and do not realize it has to be configured. |

Likely he had these same issues with his previous host - he as much as said so, the switch to dedicated hosting was the speedup hoped for. People get trapped into thinking CDNs or dedicated hosting are magic bullets for performance. They are not. Optimization, is. |

Thanks for talking this out guys, I will try to shed some light on this.
- The website was slow on the shared server too. That is why I decided to move to the dedicated server, thinking it would be much faster. I am still using a shared mySQL database. - I disabled all hooks and the website loaded much faster. See results: http://www.webpagetest.org/result/14...KMG/1/details/ So when I disabled these features (in config.php), is that turning off all plugins and/or disabling fancy fonts? Knowing this, what should be my next step? I am not much of a PHP guy and I really don't know much about configuring servers. All help is greatly appreciated! |
