Hello,

Recently we discovered huge performance drop downs in page speed / SEO on our online projects with WPML. At the moment the performance on our installations drop approximately 40 points in Google Pagespeed Insights. As an example I made some performance screenshots (before and after) from on of our projects:

WPML disabled:
hidden link

WPML enabled:
hidden link

We already tried a possible solution we found in another thread, but to no effect:
1 /** Memory Limit */
2 define('WP_MEMORY_LIMIT', '256M');

Thanks in advance for your reply.

Best regards,
Erwin Bakker

Hi Erwin,

thanks for contacting us.

Could you please try all the suggestion from here too? https://wpml.org/faq/prevent-performance-issues-with-wpml/

If nothing helps you, I'd take a copy of the site so we can further check the issue.

Hi,

thanks for the copy. I tested the page /series-modellen/tender/ with Pingdom but I didn't notice this huge difference. With WPML page speed is 1,54s and without it 1,42s.

I tried with Pagespeed insight and indeed it reports slower times responses, but it says it's mostly due to server. Since I don't know Dutch, I can't read what your screenshot says about your results, so please check if there are some warnings about the server.

I'll ask for a second opinion anyway.

Hi,

could we have your credentials so we can better test the issue?
We could also install some plugins but those shouldn't interfere with your site.
I'll enable a private reply.

Hi,

I noticed you shared credentials for nautischcentrum.nl but the site you tested is hidden link so which one is correct?

Hi,

the credentials provided do not work, however we tested on the copy of the site and from the 2nd tier they say everything seems normal, and the time registered are reasonable.

You may try installing a caching plugin W3TC to improve performance.
