Hi, Hummingbird does a great job at improving performance verified at gtmetrix and pagespeed. I have noticed over a period of 24 hours performance test results are reduced but are easy restored by clearing the Hummingbird page cache manually. Does this make any sense?
Will setting the Page Cache Interval resolve this. I am referring to the section “Cache interval Enable this feature to automatically clear cache at regular intervals only if you are required to do so. Frequent cache clearing can create significant server issues.”
Does your home page have any dynamic content, like text or images are changing? (I ask especially about images because in some cases some modules or dynamic sections on the site could load larger image size).
“Cache interval” should help for sure as a temporary fix, but it does not solve the issue of why the score is worse after some period of time. Without a full review, this will be hard to point the main issue. Do you replicate this issue each 24h?
There is no dynamic content on the page. I can not say for sure it happens ever 24 hours. I will do some testing and get back to you. Are there any other information that might help? I do see WPHB Minify Groups actions in the overnight logs. Could this be causing the change?
Thanks
Unfortunately Setting “Cache interval” did not help. The only thing that I can verify is that “Clear Page Cache” does resolve the issue every time.
Please let me know if you have any suggestions.
As long the pages are cached and the Assets Optimized the scores shouldn’t be too different, it is expected to get a different result most of the time this why we need to check the average result.
You can find more on:
Can you please check:
– Enable the debug mode on Hummingbird > Caching > Enable debug log, check the time the score goes down on the caching mode to make sure the caching are not being bypassed.
– Check the Site Health for any relevant information on Hummingbird > Advanced Tools > Site Health.
– Check the Gtmetrix > Waterfall before and after the issue, so you can find where the most load time is coming.
– And just in case, enable the debug mode and check the wp-content > debug.log for any Hummingbird line.
There’s always a possibility for that, if there was a conflict caused by something in Divi and it was patched with the update it could have addressed the issue you were having.
Cheers,
