peterJ-48	Hi Nigel, Thank you for your reply. Our developers are currently busy with our new site design. We are giving this a lot of priority because the new design is based on a simple theme and without any page builder software, which will also improve the performance. We expect to migrate to the new site design within the next 2 weeks and we will unfortunately not have time to test the patched version of 4.6.8. before after that. We typically need 2 – 3 days to test a new version, so depending on when your final solution will be released, it could be good if we can move directly to that version.

peterJ-48	Hi Christopher, We have updated to the latest version, but unfortunately we do not see any improvements, which is a surprise to me, because we can see that now the statement relate to taxonomy is only returning 20 rows where it earlier was returning 400 rows. We do have improvements compared to before Christmas, but this is due to our new site layout, that is built on a simple theme without any page builder etc. I have attached the speed tests from before and after the plugin update. At our staging server we are currently testing the plugin “Index WP MySQL” suggested by your colleague Nigel Anderson. This seams to have a positive effect on the very slow product category pages. We need to have first load well below 2,5 sec not to be punished by the search engines, so I really hope that your next major release that is scheduled for March/April will contain the necessary performance fix. The server used for our production server is: a dedicated server type: AMD EPYC 32 Cores. hidden link According to Google we still have around 3000 pages with loading time more than 4 sec. (this is the case for both desktop and mobile) please see attached. If you would like to perform some testing, then let me know and we can send a copy of the site or set up a test server.

Nigel Supporter Timezone: Europe/Madrid (GMT+02:00)	Hello, Nigel here. Thanks for sharing those details, I'm doing some testing on your site at the moment and collating results. I'll continue with that in the morning, and I'll get some feedback from the developers and update you again.

Nigel Supporter Timezone: Europe/Madrid (GMT+02:00)	I shared a summary of the results of my testing with the developers working on the performance issues, which you can see in the screenshot. Those numbers are based on what's reported when using Query Monitor, which are the page generation time and the cumulative time the database queries take. (We are not testing the browser page load times, which are affected by the content on the page including images, stylesheets and scripts, etc.) There has been an improvement on WPML 4.6.7, though page generation times are still typically about 0.6s slower than when WPML is not active. (The developers say the focus should be not be on the first page load which includes warming the cache.) One thing that they suggested is that you try the Performant Translations plugin: https://wordpress.org/plugins/performant-translations/ This will be part of WordPress core from 6.5, but using it in the meantime you may see notable improvements on your secondary language pages.

peterJ-48	Hi Nigel Sorry for my late reply. We have now tested the Performant Translations plugin: https://wordpress.org/plugins/performant-translations/ and when we are testing with our cache plugin (W3TC) disabled we can see a small improvement in loading time, but when we are testing the Performant Translations plugin with W3TC enabled, then there is no improvement. It is actually more like the loading time is slightly longer (please see image 1). I noticed that you have been testing on the home page and the shop page. It is important to highlight that the longest loading times we see is on the product category pages. On image 2 you can see the result of a load time test for our 8 main product categories in the Greek language. As you can see is the loading time for the product category pages “Manufacturing & Production” and “Electrical Items & Lighting” significantly longer than the other categories. This pattern we see for all languages. The only thing I can think of that is special for the product categories “Manufacturing & Production” and “Electrical Items & Lighting” is that they contain more variable products with many variations than the other product categories. I know from George that you are having taxonomy in focus. Is the taxonomy issue somehow linked to the slow loading speed of the product category pages, or is this something you will need take a closer look at?

Nigel Supporter Timezone: Europe/Madrid (GMT+02:00)	When I discussed this with the developers before and talked about timings, when focusing on page load times they said the first page load should be ignored, as those involved priming the caches which benefit subsequent load times. Although the first load page times appear to be more affected for those product category pages—probably not surprising if they contain a lot more product variations—the subsequent load times are very quick. I just visited your first example category archive on your live site and the subsequent load times according to the browser network tab were as low as 0.5s. That was not logged in, which is the same as a robot crawling your site would experience, if the concern is related to page ranking.
