Time To First Byte Blues...

RE: Time To First Byte Blues...
1) The redirect from asset #1 -> #2 suggests very poorly tuned Webserver config. This should be a few 100 milliseconds at most.

2) Asset #2 (since you're running WordPress on this site) suggests either poorly tuned LAMP Stack or code running on your site which is slow or maybe DNS is malfunctioning in your runtime environment.

Install the Query Monitor plugin + enable SAVEQUERIES + WP_DEBUG in your wp-config.php file + check the Debug Bar for info about queries made + HTTP requests made.

If there are many SQL reads, these should be fast + problem likely is your entire LAMP Stack tuning, as reads should come from cached memory + be faster than what's showing.

If there are many SQL writes, disable plugins or change themes, till there are no writes to render pages, where writes include INSERT + UPDATE + DELETE.

If any HTTP requests are slow, then disable related code, till you either have 0 HTTP requests (best) or all HTTP requests are fast.

If one or many HTTP requests fail, manually input each link in your browser bar. If they fail, then you'll have to edit + remove these from your code. If visiting these links works in your browser + not on your site, then likely local DNS caching is broken. I've hit this several times recently fixing client sites. The cure is generally, to switch to well tooled hosting.

3) Assets #3-#35 server pretty fast, so after you fix #1 + #2, you'll have a very speed site.
