Hi,
I am using APEX 20.1, ords-20.2.0.178.1804, DB 18c XE , windows 7 64bits, Google chrome Version 84.0.4147.125 (Official Build) (64-bit) and opera Version:70.0.3728.106.
The problem occurred too when I used 12c release 1 enterprise edition with apex 18.2 and ords 18.4.

I have a performance problem with the app builder and my custom created app. The following three videos shows the time it takes to open or submit a page in the app builder and in my custom app. There is a video with a test app page which has one form with only 5 page items which does not take long time as the app builder and my app takes but I think it's considered long as it only have 1 region.
I do not think I am violating any best practices that could affect performance. What could be the cause for that?
P.S. I cleared the standby memory and had about 500 MB free ram when recording those videos.

Edited:
I installed the database using DBCA, so, Automatic Memory Management is used.
Database, APEX and ORDS all are installed on the D partition not on C. Could that be a cause of the problem?
