Performance testing for high-load and distributed systems
Reproduce performance degradation under controlled load, and keep the exact workload, environment and runtime data attached to the result.
What you get
A performance result is only useful if you can produce it again on demand.
Repeatable load scenarios
The same workload, defined once and run again whenever it is needed
Distributed execution
Scenarios that span several hosts, nodes or devices at once
Runtime resource evidence
CPU, memory, system events and logs recorded while the load was applied
Comparison across releases
The same workload on two builds, with both sets of evidence side by side
Centralized results
One place for the runs, instead of logs spread across the hosts that produced them
Why performance failures are hard to reproduce
Performance is a property of the whole setup, so it moves when any part of the setup moves.
Throughput drops only at a particular load
Below that point everything looks fine, and the graph gives no warning
Latency changes with configuration or topology
The same binary, a different arrangement of nodes, a different answer
One host or device behaves differently from another
Which makes the average useless and the outlier the thing worth reading
Resource use grows over long runs
Nothing fails in ten minutes, and something does after ten hours
A new release behaves differently under the same scenario
Which is only visible if the previous run is still there to compare against
Performance scenarios Midair can coordinate
The load generators stay whatever the project already uses. Midair drives the scenario and keeps what it ran against.
Load testing
Behaviour under the sustained workload the system is expected to carry.
Stress testing
Behaviour near the expected limit and past it, where the failure mode is the result.
Long-running testing
Degradation over time, where the interesting data is the slope rather than the peak.
Distributed performance testing
Scenarios involving several hosts, nodes or devices, coordinated as one run.
Performance testing in Midair
Execution and observation carry this work. Code analysis joins in only when the cause looks like it is in the code.
Execute
TS Factory
Coordinates the scenario across machines and devices, and records the environment it ran against.
Observe
Delta
Collects runtime resource data, logs and system events during the run, per host.
Compare
Midair
Puts the same workload on two versions or two configurations next to each other.
When degradation looks connected to software logic rather than to the environment, Visao can be brought in to analyze the code paths involved.
Compare the same workload before and after a change
A performance regression is a difference between two runs. That only works if the two runs are actually comparable.
Only the release changed, so the difference in the resource data belongs to the release.
Where this workflow fits
High-load backend systems
Distributed services
Network infrastructure
Multi-host environments
Systems whose performance depends on configuration or topology
FAQ
What is performance testing?
Performance testing evaluates how a system behaves under different levels of load: what its throughput and latency are, and how its resource use changes as the workload grows.
What is the difference between load and stress testing?
Load testing checks how the system performs under the traffic it is expected to carry. Stress testing pushes it past that point, to find where it breaks and how it behaves while breaking.
What does Midair add to performance testing?
It preserves the test configuration and the runtime evidence, so the same scenario can be repeated and compared across versions rather than described from memory.
Start your pilot
Bring one workload into Midair, run it against the configuration you care about, and keep the resource data with the result.
