saving in edit all of tl_page is very slow

[backbone87]

ursache:
https://github.com/contao/core/blob/3.5/system/modules/core/dca/tl_page.php#L34
das rekursive generieren der sitemap wird für jede bearbeitete seite im edit all durchgeführt, dadurch wird das speichern extrem langsam, wenn man 100+ seiten bearbeitet.

What do you suggest?

How about something like for the style sheets, where the update is done when you return to the list view? I think there's something similar for news too? Maybe for the feed?

[backbone87]

there would be multiple solutions:

1. (good one) add an additional callback for DCT that is executed AFTER the storage process is completly done (it maybe should provide the table and the IDs / fields that were edited)
2. (good one) generate the sitemap on demand (with transparent caching), so you just delete the sitemap, when a page is being edited, and the next time someone requests the sitemap, its get generated
3. (not so good one) set a flag somewhere and generate the sitemap in another step

1. This seems to be a good solution indeed, although we'd have to wait for the next minor version to implement it.
2. This is difficult, because sitemaps are stored as .xml files and we'd somehow have to redirect the request to PHP, which requires mod_rewrite.
3. Might not be as good a solution as 1., but does already work for news and calendar feeds. Could maybe be implemented as hotfix.
