Question { TCS, 14105 }

What is the difference between Performance testing and Load
testing ?

Answer

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
