Big slow down in 4.51.0

[jellebreuer]

Bug description

When i upgraded my site (1000+ unique entries) i noticed the base loading time increased with about 300ms, just to find the right page. After installing different versions and adding a ton of dumps i found the culprit:
#5502

Specifically the part in BasicStore.php@getItem

        if (method_exists($item, 'syncOriginal')) {
            $item->syncOriginal();
        }

If i remove this piece of code and revert it to how it used to be , with it being called explicitly in the children stores, the slowdown goes away

How to reproduce

• Have alot of unique pages with unique uri
• Add a timed measure around this part in CollectionStructure

            $thisCollectionsEntries = $this->collection()->queryEntries()
            ->where('site', $locale)
            ->get(['id', 'site'])
            ->map->id();

Measure it in 4.50.0 and 4.51.0 (or the latest version)
See the slowdown

We've made a bunch of performance related improvements in v5, which we're hoping to release in the next few days. Would you be able to try updating your site to the v5 alpha to see if that improves performance at all?

[jellebreuer]

@duncanmcclean I tried the latest alpha.

In general page does seem to load better. Things like $page->url() are fast again.
Only the base response time, matching the URI to an actual page is still really slow compared to 4.50.0. (700ms)
Only the slowdown seems te have moved somewhere else. Ill try to find the new place its coming from.

@duncanmcclean never mind, v5 fixes the problem, slowdown was caused by laravel debug bar. PS really nice that you can see the stache queries in there now!
