Slow backend (articles only) due to one query

Post by perrineco » Mon Sep 17, 2018 10:49 am

Hello

I noticed my back end is very slow when I try to access the articles. I checked the debug console and find one query is very slow. So I dived into the code and at the end, saw that the line 73 in JROOT/libraries/src/Form/Field/AuthorField.php makes the page to be very slow

If I comment this line (static::$options[$hash] = array_merge(static::$options[$hash], $options);) the page loads quite faster. I don't know if it is important or not.... Any help?

Moreover I used Chrome developpers tools and looked at the network tab when the line 73 was not commented. I notice the first requests look like normal. Then at some point nothing happens and after 2 min the following requests are processed. I tried to show it in this pic

Thanks a lot for your help. What should I do?
