GX-Entwicklung

Wenn man viele Bestellungen hat und viele GX-Customizer Uploads, ist der Warenkorb sehr langsam.
Das Problem hier ist, dass beim Aufruf des Warenkorbes immer geprüft wird ob noch Kunden die schon lange nicht mehr im Shop aktiv sind noch Dateien hochgeladen hatten aber die Bestellung nicht abgeschlossen haben.

If you have many orders and many GX customizer uploads, the shopping cart is very slow.
The problem here is that when calling up the shopping cart it is always checked whether customers who where not active in the shop for quite some time have uploaded files but have not completed the order.
