Hi

I'm having some trouble setting up my photo album. I need your help ... it will probably be obvious, once I will have mastered the configuration !!!
Three questions
1 - What is the difference between "cover" and "thumbnail"
2 - I wish to have a presentation of small photos and if I click on one of these small photos, I wish to have the large photo version.
3 - How to manage an album: deletion of a duplicate or add a new one, replacement of a photo, correction of a description ...

Hi everybody,

I have a D8 custom module with a custom form and I want to calculate the time with microseconds between the page load and the user submission of the form.

I did it with d7 and now want to port this code to D8 for studying and understanding D8 but I'm stucked.

in the D7 version I successfully did it with these lines of code:
if (variable_get($random_code) == NULL) {
       variable_set($random_code, microtime(true));
}
$form_state['cache'] = TRUE;

Running a site on Drupal 8.7 with lightnest. 

Site was working fine but until recently a web form reached around 40K entries and I am experiencing out of memory error.

The webform is just receiving data, no listing of data whatsoever required.

Profiler shows an average process is taking around 50-60MB memory. 

Server has 8GB of ram and log shows that at peak times it has 170+ httpd process running. 

We have reduced the number of max client connections.

Question:

1) is 50MB high or low for a page to load?
