We have a lot of optimization efforts already in place. However, we're seeking a major improvement to what we have now. We're not looking for someone to simply configure a popular cache plugin. We know how to do that and already have. We're well past that point. We need an expert who's confident they can significantly improve the speed and performance of a wordpress driven site that has a lot of plugins (58 active).
Currently, here is the environment:
We have 4 performance tools running.
1. There's a server level Apache process running on on WHM called NGINX.
2. WP cache plugin called WP Fastest Cache (Pro version) for browser cache, zip compression, CSS/JS optimization, etc...
3. CDN for off-site hosting of images. We're using Jetpack for this.
4. A plugin called "Plugin Logic" that handles allows granular control over which plugins files are loaded on which page. This above all else has given us the most speed boost. However, as you'll see it's heavily configured to make it work.
We are open to changes in the software employed if confident it will deliver improvements.
With those site wide tools covered, here are two areas acting especially sluggish we would like to see big improvement too.
After #4 was setup, average page load times greatly improved. The two search pages titled "Jobline" and "Showcase" on the main menu contain a Ajax driven faceted search plugin called "Facetwp". This plugin is very important to the site model but it seems to be exempt from any form of cache optimization I've thrown at it. You will notice that the basic page elements actually load very fast, but the search elements take much longer.
Homepage w/ video
We have a long homepage and no fat to trim at this point. It holds a HD vimeo video that's especially cumbersome. It currently takes 4-8 seconds to load on average. We'd like to improve this.
The plugin "Plugin Logic" while very good at selectively loading plugins on the front end, doesn't help us on the backend. It's very slow in the backend. We'd like this improved.
If interested in the job, I will provide a link to the staging domain in private message.
Please let me know what questions you have for me. Thanks.
