Guide to Performance Testing, Types and Most 
Common Issues Faced in Performance Testing 
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.
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.
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?
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.
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. 
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.
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.
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.
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.
