Standalone console harness under tests/ZB.MOM.WW.ScadaBridge.LoadHarness plus a scaled-down Category=Performance smoke [Fact] in PerformanceTests. Deliberately an Exe rather than an xunit suite: the Performance trait enables a filter but does not exclude by default, so a 20-minute test would run on every 'dotnet test' of the slnx. What is real: per-site ActorSystem + LocalDb SQLite file, the real DCL (DataConnectionManagerActor/DataConnectionActor over a SimulatedDataConnection registered through the documented DataConnectionFactory.RegisterAdapter seam), real InstanceActors fed real TagValueUpdates, the real SiteStreamManager, real StreamRelayActor + production-capacity bounded DropOldest channel, real StoreAndForwardService/Storage, real SiteHealthCollector + CentralHealthAggregator. Only the socket hops are stood in for. Measures: end-to-end tag update latency (the emit instant rides TagValueUpdate.Timestamp verbatim to the subscriber), instance ramp, memory growth/CPU over a steady-state window, health report and debug view latency under load, S&F concurrent buffering + drain throughput, and slow-subscriber isolation.

Target-scale load harness (deferred-work register #25 / Phase-8 WP-4, absorbing row 50).
|
|
|
|
Deliberately an Exe, not an xunit project: the full-scale protocol is a
|
|
~20-minute sustained run at 10 sites x 500 instances x 75 tags, which must NOT
|
|
execute as part of `dotnet test ZB.MOM.WW.ScadaBridge.slnx`. The PerformanceTests
|
|
project carries a tiny scaled-down smoke [Fact] that references this assembly so
|
|
the harness stays compiled and exercised by CI without the runtime cost.
