Load & Performance Testing — fast on launch day, every day

Slow pages lose customers and crashes lose trust. We simulate real users at scale to show exactly how your website, app and APIs behave under pressure — and where to fix them before your next big launch or sale.

Overview

Know your limits before your customers find them

Your platform might work perfectly for ten users and collapse at ten thousand. We recreate realistic traffic — logins, searches, checkouts, API calls — and measure response times, errors and resource usage, so you can scale with confidence.

Without regular testing, you risk:

  • ●Crashes during launches and sales
  • ●Slow checkouts and abandoned carts
  • ●Unplanned infrastructure costs
  • ●Poor app-store ratings and reviews
  • ●SLA breaches with enterprise clients

What we test

Tests we run

Click a category to see what we look for — and a real example of what we find.

Load Testing

Your expected peak traffic, end to end.

WHAT WE TEST

  • Realistic user journeys
  • Concurrent users & throughput
  • Response times (p50/p95/p99)
  • Error rates

EXAMPLE RESULT

3,000 users → checkout p95
8.4 s (target 2 s)

Stress Testing

Pushing beyond the peak to find the breaking point.

WHAT WE TEST

  • Maximum capacity
  • Failure behaviour
  • Recovery after overload
  • Graceful degradation

EXAMPLE RESULT

Breaking point at
4,200 concurrent users

Spike Testing

Sudden surges like a sale, campaign or viral post.

WHAT WE TEST

  • Instant traffic spikes
  • Auto-scaling reaction
  • Queueing & caching
  • Third-party limits

EXAMPLE RESULT

Auto-scaling took 7 minutes
→ errors during the spike

Endurance (Soak) Testing

Steady load over hours to reveal slow leaks.

WHAT WE TEST

  • Memory leaks
  • Connection pool exhaustion
  • Log & disk growth
  • Performance drift

EXAMPLE RESULT

Memory grows 300 MB/hour
→ restart needed daily

API Performance

The services behind your apps.

WHAT WE TEST

  • Endpoint latency
  • Throughput per service
  • Database query timing
  • Third-party dependencies

EXAMPLE RESULT

Order search query
takes 6.2 s under load

Bottleneck Analysis

Turning results into faster, cheaper infrastructure.

WHAT WE TEST

  • APM & server metrics
  • Database tuning
  • Caching & CDN
  • Right-sizing infrastructure

EXAMPLE RESULT

Adding cache cut page time
3.1 s → 0.6 s (illustrative)

FAQ

Questions before you start

Will load testing affect real users?−

We recommend a staging environment that mirrors production. If production is required, we test in an agreed low-traffic window.

How many users can you simulate?+

From hundreds to many thousands of concurrent virtual users, depending on your goals and environment.

Do you help fix performance issues?+

Yes. We pinpoint bottlenecks and work with your team to tune and re-test.
