page load time first byte

I consistently get over 500-1000 mil secs on my time to first byte score from webpagetest.org.

Any thoughts on debugging the page load speed. I have used executioner and most snippets and chunks are between .1 -.3 second. I have about 4-8 chunks and snippets called per page, including wayfinder which is cached. I am caching everything I can. I am using these packages:

getResources
phpthumbof
getResourceField
getPage
wayfinder
formit
formitsave
tinymce

The server is the latest ubuntu release with 4 gigs of memory. I am running modx 2.2.5

Any suggestions are appreciated. [ed. note: digitalbart2 last edited this post 11 years, 6 months ago.]

Could you tell us more about how apache/php is configured on your server, for example do you use fastCGI or suPHP? Do you use a MPM handler?

A "quick" fix would be to install xFPC: http://modx.com/extras/package/xfpc and see if it helps any.

Also do all pages suffer from the delay or just one page, and if so what is on the page in question?

Are you noticing slow times to server HTML when doing things like browsing the front end of the site and viewing the source? I ask because even Google.com gets 0.4s for first byte on that particular test

xFPC is amazing! I was faster than Google...(?) about 200-300ms on average. Thank you for the suggestion. It was on most pages and it is much much faster now.
I am just curios now can I have something prime the cache once a page is updated? [ed. note: digitalbart2 last edited this post 11 years, 6 months ago.]

We updated the front we are using typekit, google maps and both are now loaded async. We also installed mod_pagespeed for google. It was still slow, but xFPC speed up everything much faster than anything I have ever seen before.

We will be releasing a script that will crawl your sitemap.xml to reindex the cache, you could trigger that after a page save or manualy.

Thank you, I'm looking forward to it.

It sounds like RefreshCache does what you are looking for

Thanks, I will give that a shot.

Make sure you don't click the button twice! And be prepared for the potential of too many requests bringing your server down (have that hosting support line ready
