I'm doing the System Architect Essentials and I'm currently on the Exercise: Designing a data model. When I open the training environment (the cloud solution) it takes exceedingly long to load. After it's loaded adding fields or configuring proces steps barely doable. The system is unworkable. I've added a GIF (run time 2 minutes) showing the problem.
I have tried resetting the exercise system, but it only seems to be going slower.
Maybe it helps for new Pega consultants to know that after a few hours I tried again and now it runs very smooth. I think I got rerouted to another Pega cloud server. In the mean time you can always continue other assignments.
Similar course - Business Architect Essentials, which takes user through extremely similar steps as the System Architect Essentials.
Issue is Data Source related, exercise system for course section 18 of 29, Configuring Reference Data.
Tonight is better than last night where I just stopped, skipped the exercise, moved forward. Thought I'd try tonight to retry it. After a minute tonight it did come back, but still extremely frustrating. Just back from vacation so needed to get in the system, but...hopefully some folks will see this and help.
I'm currently running the exercise system via VM VirtualBox. After some tweaking its only somewhat slower than the cloud version on good days, however, the lag is always the same so you know what to expect. No more sudden performance drops, no more frustration.
I found the exercises quiet helpful and actually a vital part of the training. I would not recommend skipping them all together.
It's the same in Chrome, Edge, and Opera. For what it's worth, I'm on System Architect Essentials (8.1). Any click within the system (e.g. save, submit, click a drop-down list etc), leads to a 5-10 minute wait while the action resolves.
