Answer / selia

Performance testing is the superset of load testing. Load
testing involves testing how well the system is able to
handle concurrent users or the load. Whereas performance
testing comprises load as well as stress testing.

Answer / hiren

In performance testing we will try to keep more stress(i.e
maximum stress specified by client)on system and check
whether the system performing the same way as for less
stress condition.whereas in Load testing we will keep stress
beyond the limit specified by client to check from which
point system's performance getting decrease.

Answer / anuradha

performance test consists of both load testing and stress
testing too . In load testing we check point at which
system / application crashes . Let us take one example if
we design website which can handle ( capacity ) 100
concurrent user(100 users can performe the task on
website ) . If we put 1000 concurrent user then system
response gets down , it may crashes ,it's a saturation
point .

I am Sripathi Venkata Ramesh from Gudivada and the answer
is mentioned below

Performance Testing - It is mainly based on the speed of
processing


1. load testing - Testing the Maximum load of the
application while accession at the same time with out
compromising with the response time


2. Stress testing - testing the behaviour of the system or
application while applying heavy stress that is man power


3. Volume testing - testing the application for large
volume for data is called volume testing. This is mainly
conducted to check the memory leaks and capacity of the
server handling huge volume of data.

Answer / parry

Load Testing - Check the user's response time no of users
using any one senario of the same application at the same
time.

Performance Testing - Check the user's response time no of
users using multiple senario of the same application at the
same time.

Answer / bala p

Load testing mainly deals with the scalability/number of
users using the application
Performance Testing is done to understand the basestate of
the application. It includes response time Requests per
second etc

Answer / rahul phapale

In Performance Testing,We check the performance of the
system.We measure performance using throughput and response
time.Throughput is noting but capacity of the system to
handle multiple transaction.Response time is the time
between first request and first output.
e.g The capacity of the system to perform 100 transaction/second
Load testing and stress testing is the subset of Performance
testing.
In load testing, we measure the system performance under
reasonable load.For example you have given the system which
supports the 100 concurrent user.So then you can test the
system performance with 100 concurrent user.
In stress testing, we test the system with unreasonable load
for which system can't handle the request.Thus,we confirms
the upper limits of capacity of the system
