Load Testing Service

Know your traffic ceiling before your users find it .

Project-based load testing for pre-launch validation, Black Friday prep, and holiday traffic spikes. We run k6 and BlazeMeter test plans against your stack, interpret results, identify bottlenecks, and deliver a fix-priority report. 17 years of infrastructure ops, 35 engineers.

What a ZenoCloud load test engagement covers

Not just running a k6 script. A full engagement — test plan design, execution, interpretation, and actionable fix recommendations.

Test plan design

We design test scenarios based on your real traffic patterns — peak concurrent users, critical user journeys, API endpoints under load. Not a generic ramp-up script against your homepage.

k6 and BlazeMeter execution

Industry-standard tooling: k6 for scripted, code-first load tests and BlazeMeter for distributed, multi-region load generation. We run from staging or with production safeguards in place.

Bottleneck identification

We correlate load test results with server-level metrics: CPU saturation, database connection pool exhaustion, memory pressure, slow query patterns. We find what breaks first — and why.

Database and cache under load

Databases and caches fail differently under load than in development. We test MySQL/PostgreSQL query response at concurrency, Redis eviction behaviour, and connection pool limits before your users do.

Fix-priority report

Deliverable is a written report: observed breaking point, top 3–5 bottlenecks ranked by impact, fix recommendations per bottleneck, and estimated effort. Your engineers know exactly what to do next.

Pre-launch and event-ready timelines

Black Friday or a product launch has a fixed date. We scope engagements with enough lead time for a test, fix cycle, and re-test — typically 3–4 weeks from kick-off to final report.

Pricing

Load testing engagement pricing

Project-based — not a recurring subscription. Scope depends on application complexity, test environment setup, and desired concurrent user targets.

  • k6 load test execution
  • Up to 5,000 concurrent virtual users
  • Server metric correlation during test
  • Written bottleneck report with fix priorities
  • 1 re-test after fixes (within 30 days)

High-scale, multi-region, or compliance-sensitive workloads

  • Custom test plan: unlimited user journeys
  • Multi-region load generation
  • Up to 100,000+ concurrent virtual users
  • Full observability during test run

Pricing above is for test execution on staging environments. Production load tests (limited traffic injection alongside real traffic) priced on request. Optional monitoring retainer ₹15,000/mo for ongoing performance regression detection after an engagement.

Managed load testing vs running k6 yourself

k6 is free. Knowing what the results mean — and what to fix first — is where the value is.

FAQ

Load testing — common questions

When should I book a load test?
At minimum 4 weeks before a fixed traffic event (launch, Black Friday, a major product drop, or a high-traffic campaign). This gives time for: kick-off and test plan design (1 week), execution and analysis (1 week), fixes by your engineering team (1–2 weeks), and a re-test to validate the fixes. Last-minute tests 1 week before launch are possible but limit your ability to act on findings.
Do you test against staging or production?
We recommend staging environments that closely mirror production — same server specs, same database size, same cache configuration. We can run limited production tests (injecting synthetic traffic alongside real traffic at off-peak hours) but this requires more careful scoping to avoid user impact. Most clients test on staging, fix, then deploy to production with confidence.
What is the difference between k6 and BlazeMeter?
k6 is a code-first load testing tool — test scenarios are written in JavaScript, which gives precise control over user flows, authentication, API calls, and stateful sessions. BlazeMeter adds distributed, multi-region load generation when you need geographic realism or concurrent user counts above what a single machine can generate. We choose the right tool based on your test requirements.
What does the bottleneck report include?
The ZenoCloud bottleneck report covers: observed breaking point (concurrent users, requests/sec at failure), top 3–5 bottlenecks ranked by impact (with the specific metric that showed the constraint), and fix recommendations per bottleneck with estimated engineering effort. We also include annotated graphs showing exactly when each metric hit its limit during the test run.
What happens after the test? Can we get ongoing monitoring?
After an engagement, you can add an optional monitoring retainer at ₹15,000/mo. This covers ongoing performance regression detection — we configure Grafana alerts for the key metrics identified during the load test, so you know immediately if a code deployment degrades performance. About 30% of load testing clients add the retainer.
Can you test APIs as well as websites?
Yes. API-heavy stacks (REST APIs, GraphQL, gRPC microservices) are well-suited to load testing and are increasingly our most common engagement type. We design test plans that simulate realistic API call patterns including authentication flows, sequential calls that depend on previous responses, and mixed read/write workloads.
