Webforms are very slow with revisions and drafts enabled.

We found a workaround for this.

We uninstalled config_entity_revisions

and then installed the config_revision module instead.

Then from the administrative interface /admin/config/development/config-revision provided by this config_revision module
put a checkbox beside 'webform' and save.

If you are using Drupal 10.1.5 or higher you will not require a core patch to use this module.

Oh, I'm sorry - I forgot all about trying your form.

I'll seek to do so and hopefully the work around won't be needed.

Hi Joseph.

I'm trying to reproduce this now, without success so far, using your sample form. Any further hints you might be able to provide would be appreciated. I'm using the dev version of config entity revisions.

Hi Nigel,

It's been a while but from memory it occurs after having made a "few revisions" of a "fairly complex webform" and when the "save draft" option on a webform is.

I've provided a fairly complex example webform, if "save draft" is enabled , and config_entity_revisions is enabled, make some revisions of that webform then make some drafts. You'll see the slowness when you try to recuperate your draft form or when saving the draft, one of the two.

If save draft is option is disabled, the performance issue goes away.

However if not using config entity revisions, deleting all revisions, save draft works.

Thanks. I'll give it another go.
