Andreas W. WPML Supporter since 12/2018 Languages: English (English ) German (Deutsch ) Timezone: America/Lima (GMT-05:00)	Sorry, but this analysis by Code Profile seems not correct. It says WPML causes a load time of 9.5 seconds on: https://wpml.org/forums/topic/performance-issues-with-acfml/ If I open this URL in a browser tab it loads in 2 seconds. Could you please clarify where I can see such long loading times on the backend or which steps I need to take?

Philip	Hi Andreas, Thank you for your review and for your time. I have applied the fix you recommended here https://wpml.org/forums/topic/performance-issues-with-acfml/ but I do not see it somehow made things better for us. I did some comparison tests again today on these pages: hidden link - Dashboard hidden link - Posts So, here you can see the difference on loading time: hidden link BTW, this is what we have in LIVE for same pages but with all plugins active: hidden link If we'll closer take a look what happens on Posts page (let's consider Dashboard is quite good at the moment) we'll see the following: 1) wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/fp/core/functions.php takes 3.37 sec to load. This is what we have in LIVE: hidden link 2) These methods are on the top when we check loading time: hidden link 3) This query takes almost a second to load: SELECT option_value FROM wp_options WHERE option_name = 'icl_sitepress_settings' LIMIT 1 For all these points we have to keep in mind that only WPML & ACF are active for now so it's actually not a "real condition". BTW, in my browser console I also found this process take 3-4 seconds to finish: hidden link Maybe you know if this sync can be somehow optimized to work faster? If you have any other optimization ideas or tips on how to improve the situation in terms of admin panel speed - please let us know.

Andreas W. Supporter	I am sorry, but I do not see such high load times on your site. Dashboard and Posts load here in 2-4 seconds. Also, we are talking here about background tasks on WP Admin. Load times up to 10 seconds are very common in such cases. If the load time would be significantly higher we could investigate further, but for this I really need to see an issue when loading a page. What I generally can suggest for your site: Your server uses PHP 7.4.33. You will get a way better performance using PHP 8.3.xx

Philip	Hi Andreas, I'm preparing tests now to give you information on how WPML affects page loading. Please give me 1-2 days to prepare everything for you. Thank you,

Andreas W. Supporter	Before running the tests, please consider updating PHP on your server. From my last comment: Your server uses PHP 7.4.33. You will get a way better performance using PHP 8.3.xx I will be awaiting your feedback.

Philip	Hi Andreas, Yes, we have upgraded DEV environment to PHP 8.1.31 So, to confirm our thoughts that WPML affects page load speed - we have installed the WP Shifty plugin which allows to disable plugins on specific pages. Having this feature, we also have Code Profiler to change the speed difference. We saw that when all plugins are activated, the page load speed of the All Pages page is 30.2768s, next we disabled for this page these 4 plugins: - WPML Multilingual CMS - WPML SEO - WPML Media Translation - WPML String Translation Next - we ran Code Profiler on the same page and page load speed now is 10.5669s Please see: hidden link Also, we can see that the number of SQL queries has decreased significantly (4,333 items -> 2,109 items): All plugins enabled: hidden link WPML plugins disabled: hidden link In other words, we can definitely see that a third of the time is taken up by WPML. Could you look again? Your accesses are working and up to date. Also, the page is now accessible and running fast hidden link (since WPML is disabled on it) but you can re-enable them here hidden link : hidden link Please let me know your thoughts on this.

Andreas W. Supporter	Hi, I would like to offer to take a closer look and request temporary access (wp-admin and FTP) to the site to investigate the issue further. The required fields are below the comment section when you log in to leave the next reply. The information you provide is private, meaning only you and I can see and access it. IMPORTANT Please be sure to back up the site and database before granting us access. If you can't see the "wp-admin / FTP" fields, your post and site login details will be set to "PUBLIC". DO NOT publish the data unless you see the required wp-admin / FTP fields. I may need to install a plugin called "All In One WP Migration" here to create a copy of the site that I can use to investigate the issue further. However, I would also be very grateful if you could provide a staging site or copy of the website from your server for this purpose. If you have any questions about creating such a staging site, you can consult your hosting provider. Please note that WPML must also be registered on this staging site at https://wpml.org/de/account/websites/. If you are not able to provide such a copy of the website for testing, please let me know on this ticket. The private reply form looks like this: hidden link The next time you reply, click on "I still need assistance". Video: hidden link Please note that we are obliged to request this information individually on each ticket. We are not allowed to access any credentials that were not specifically submitted on this ticket in the private response form. Best regards Andreas

Andreas W. Supporter	On a first visit to Seiten > Alle Seiten and revise the Performance Tab in Google Chrome the page loads completely in 10 seconds. The first-page load might always take longer than the upcoming ones. See screenshot. Testing without WPML takes about 5 seconds. The higher load time can be expected due to the amount of active language that WPML needs to filter. Activating WPML and opening the page again I get 5.7 seconds load time. Disabling "Admin Menu Tree Page View" the load time even goes down to 3.5 seconds with WPML active. It is kind of expected that the plugin "Admin Menu Tree Page View" enhances the load time as it adds many new menu items to the dashboard. I can not see any issue caused by WPML on the site. Maybe you got a different example? --- Also, please register WPML on this site and run the latest updates at Plugins > Add new > Commercial.
