[Feature Request] Performance and Load Testing

[henrik-me]

Build infrastructure to measure performance and load metrics on a continuous basis ensuring that releasing can be done so with high confidence that no performance sensitive scenarios are broken.

We should be able to answer questions such as:

• How many users are supported?
• Latency in various configurations
• How does using redis impact cache performance
• How many users can we handle using various combinations of cache?
• Cache failure rates (telemetry data point), e.g. Redis is know for failures.
• Cache misses (telemetry data point)
  and many many more

Findings during the performance and load testing should be turned into new features/bugs and addressed.

Next: More detailed requirements to be defined.

The questions around the cache are dependent on a small improvement in MSAL: AzureAD/microsoft-authentication-library-for-dotnet#1728

@henrik-me Should I close this issue, since we completed GA criteria work? Afterwards we can create separate issues for each perf task that will be done?

Let's mark it as fixed. We'll close it with the milestone.
