Performance testing verifies loads, volume and response time as defined by requirements while load testing is testing an application under heavy loads to determine at what point the system response time degrades.

The concept and exercise of Load testing is after the performance testing. The Performance testing is something where we find the response time of the appication, Look out the Bootlenecks & Tune it. This testing includes in different layers Like Application Layer, Network Layer, Database Layer & OS Layer After fixing the defects from the Above layers then comes an exercise to perform a Load Testing.

A Load testing is done once if the functional and Performance testing is up and done to check the minumum and maximum load the Application can handle. (Thanks! Illur Iqbal.. New Delhi)

It its right.but I think performance testing uses the load testing inorder to know the response time with respect to the varying load.

Load Testing:

LoadTesting is used to apply a predetermined load and find out the responsetime of the application

Performance Testing:

It is used to find out the response time of the application in mutiple user environment

load testing : To test the statistically representation of the system.

perfomance testing: To test the compliance of the system  or component with in the specificaton limit of the component,

Performace Testing -

Performace testing is just to check the responce time/throughput of the applicaiton and test the standard requirement of applcation.

Load testing - Is the kind of testing which is done by increasing the load on the application from he normal. for e.g no. of Vusers.

Hi !!Load Testing is subset of Performance testing .In Load Testing the number of users increases

Both Performance Testing and Load Testing are different, But, both looks similar because the measurements used in analysis are same for both.


Performance Testing is done to understand the basestate of the application. It includes response time, Requests per second, etc


Where as Load Testing is done to find out the scalability of the system. For example, finding out the maximum number of users supported by the system with certain specifications. Here also, we need to measure the response time, Requests per second, throughput, etc.

In stress testing, we measure the recoverability of the system. For example, how the system recovers when we shutdown the DB while transaction is going on.

Or in another way, Load Testing comes under positive tests and stress testing comes under negative tests. And performance tests measures the basestate or performance of the system.

Load testing is one for objective while planning performance test. It is subset of performance testing while performance test maesured by various subset of testing like benchmark, load, stress contention test etc.

Performance Testing: It determines end ot end timing of various time critical business processes and transactions, while the system is under low load, but with a production sized database (all the data you have, actual size of data). Find an optimal time to and from the system and use it as a benchmark. This benchmark is used as a reference against all the future performance/load tests. Without performance testing, we won't know how the application will behave under concurrent and multi-user load.

Load Testing: End-to-end performance testing for an anticipated production load (the number of users/transactions that are meant to be handled by the system at a given time); measure response time under various time critical and business processes. If the response time is greater than the requirement, the test fails. If it is less as compared to the time as required by the client, the test passes. (How does the server behave when too many concurrent user requests come to it?) (3 seconds is the default threshold given to the server as user waits)

Performance testing verifies many non-functional features of the software but load testing tool focuses on the load up to which it can sustain.

Load Testing - Load testing is performed to determine a system’s behavior under both normal and anticipated peak load conditions

Performance Testing - It involves testing software applications to ensure they will perform well under their expected workload.

In real time load test is a part or subset of performance test. In load test we check the application behavior under normal and heavy loads. i.e as the no of vsuers increases how the application behaves. Where as performance test checks response time, throughput , cpu utilization, memory and file handling etc...
