Hello,
We understand that caching is an important part of my websites with the intent to increase page speed. One thing to keep in mind, is that unlike static wordpress pages and blog posts, the the IDX listings and html exists on our servers, and its served through Optima Express dynamically. I would expect it to take a little extra time when compared to a blog post.
Ultimately, a page load time of the search form of about 3 seconds is in the ball park of what I see on other sites using Optima Express, which includes are demo site.
We recommend strongly against caching because it can affect the way our plugin updates cookies or the listing data. If you absolutely must use caching I would recommend looking into options for page exemptions. Some caching programs will allow you to white list pages that will not be cached and this could help you avoid running into issues with outdated data and make sure user sessions are tracked.
That being said we really do appreciate your feedback and I’ll make sure our product team knows that our clients are interested in caching.
If you have additional questions, please feel free to reach out to us at [email protected]
Best,
