Baseline API load profiles
Define expected and peak concurrency for critical SaaS APIs, then run controlled ramps that mirror real traffic patterns.
PERFORMANCE TESTING
Baseline API Load Testing for SaaS Teams
QAFactory runs baseline API load tests to measure latency, throughput, and error rates under expected and peak concurrency — then pinpoints bottlenecks before they hit production.
API LOAD BASELINES
Establish API performance baselines before release
SaaS and product teams use QAFactory performance testing to prove critical APIs hold under load. A Forward Deployed QA Engineer owns scenario design, ramp profiles, bottleneck analysis, and release-risk evidence — not a one-off script dump.
BOTTLENECK FOCUS
Find where APIs break under load.
Baseline load testing tied to release risk
| Signal | What we measure | Bottleneck outcome |
|---|---|---|
| Response time | p50 / p95 / p99 latency on critical API paths | Slow endpoints and heavy handlers isolated |
| Throughput | Requests per second at target concurrency | Capacity ceiling before saturation |
| Error rates | 5xx, timeouts, and dependency failures under peak | Failure modes mapped to services and deps |
| Concurrency | Ramp from baseline to peak user/API load | Contention, queueing, and lock hotspots surfaced |
WHAT YOU GET
API load evidence your eng team can act on.
Baseline profiles, bottleneck reports, and clear release-risk recommendations — owned end to end by a Forward Deployed QA Engineer.
Bottleneck identification
Trace latency, throughput, and error spikes to the endpoints, dependencies, and resource limits that throttle scale.
Release-risk evidence
Ship a clear pass/fail picture with charts, failure modes, and prioritized fixes before the release window closes.

FAQ
Questions before we start.
What does QAFactory performance testing cover?
We validate how critical journeys behave under expected and peak load — including response time, throughput, error rates, concurrency, and bottleneck analysis — then report release risk with clear evidence.
Is performance testing included in Managed Forward Deployed QA?
Core managed plans start from $2,499 per month. API, performance, or security scope is available as Expanded QA Capacity and is confirmed in writing before work begins.
Can we start with a smaller engagement first?
Yes. Begin with a 48-hour QA audit from $299 to surface release risk quickly, then expand into ongoing Managed Forward Deployed QA from $2,499 per month if you need continuous coverage.
How does pricing work for performance scope?
Public starting prices are the 48-hour QA audit from $299 (one time) and Managed Forward Deployed QA from $2,499 per month. Performance load scope is sized to environments, scenarios, and peak targets, then confirmed before engagement.
Baseline your APIs before peak traffic hits.
