Many Dynamics 365 projects still treat performance testing as something to do near the end of implementation.
That is usually too late.
In practice, most performance problems are not caused by Azure or by the platform itself. They are usually the result of earlier decisions around solution design, integrations, customisations, batch architecture, reporting workloads, and data volumes.
That is why performance testing should not be seen as a technical exercise before go-live. It should be treated as an architectural validation of whether the solution can handle real business operations under realistic load.
A few common mistakes appear again and again in Dynamics 365 projects:
performance testing starts too late
teams try to test everything instead of critical scenarios
non-functional requirements are not defined clearly enough
test environments and data volumes do not reflect production reality
The better approach is to define performance expectations early and test the scenarios that matter most, such as:
If these workloads are not validated early, projects often discover bottlenecks when major design changes are already difficult and expensive.
I have written a fuller guide covering:
why cloud does not automatically mean good performance
who owns performance across customer, partner, and Microsoft
how to define meaningful performance targets
what foundations are needed for realistic testing
which design decisions usually create the biggest problems
If you are planning a D365 implementation or reviewing an existing solution, early performance planning can save a lot of pain later
