2. Application performance testing services concentrates on how a system works under a
specified load. This is not about discovering software bugs or errors. Application performance
testing services measures as per benchmarks and standards. Performance testing should give
developers the diagnostic data they require to reduce bottlenecks.

3. Load testing
Load testing defines system performance as the workload rises. That workload could mean
simultaneous users or transactions. The system is controlled to regulate response time and
system staying power as workload rises. That workload drops within the parameters of
standard working circumstances.

4. Stress testing
Unlike load testing, stress testing — also called as fatigue testing — is intended to estimate
system performance other than parameters of normal working circumstances. The objective
of stress testing is to estimate the software stability. At what point does software break, and
how does the software recover from failure?

5. Spike testing
Spike testing is a type of stress testing that estimates software performance when workloads
are considerably expanded quickly and frequently. The workload is beyond typical
expectations for a short span of time.

6. Endurance testing
Endurance testing — also identified as soak testing — is an evaluation of how the software
functions with a typical workload over an extensive amount of time. The purpose of
endurance testing is to examine for system problems such as memory leak.

7. Scalability testing
Scalability testing is utilised to ascertain if the software is efficiently handling growing
workloads. This can be resolved by constantly adding to the user load or input volume while
controlling system performance. Also, the workload may wait at the same level, while
devices such as CPUs and memory are altered.

8. Volume testing
Volume testing defines how efficiently software functions with a large, extended amount of
data. It is also recognised as flood testing as this test overwhelms the system with data.

9. Most Common Obstacles Observed in Performance Testing
Speed concerns — slow responses and long load times, for instance — often are recognised
and addressed. But other performance issues can be observed:
Bottlenecking — This happens when data flow is hindered or paused because there is not
sufficient capacity to manage the workload.

10. Poor scalability — If software cannot control the desired number of collective tasks, results
could be delayed, flaws could build, or another unexpected behaviour could result.
Software configuration issues — Often, settings are not set at an adequate level to manage
the workload.
Inadequate hardware resources — Performance testing may disclose physical memory
limitations or low-performing CPUs.
