I've been using Power Platform with Canvas apps and SharePoint lists for some time. Not lightning fast, but "OK".
Now that I'm using the Dataverse and model-driven apps, I'm shocked at how *SLOW* everything is! All I'm doing is some rudimentary imports of Excel data (via dataflows), creating tables/dataflows, using Dynamics 365 for bulk deletes, etc. EVERYTHING IS SO VERY SLOW!
After being accustomed to in-house server-based tools (Oracle, SQL Server, C/C++, .Net, etc.) have I become "spoiled"? Is the "new way" to just lower expectations and assume dataverse (cloud) runs horribly slow, and that's how it is?
I've been in IT since the early 80s, using PCs, minis, mainframes and Unix. I have *NEVER* seen anything as slow this since batch-processing runs on a Univac mainframe in the late 70's at college.
Note: I'm using a G3 (not commercial) tenant.
