EKA’s product and
services
With vast experience in hundreds of testing projects (functionality
testing, test automation and performance testing ) in the last 15 years,
EKA has developed test frameworks, technology and tools which help
in doing cost effective and efficient testing
– CBTF, a cloud based test platform with built-in test phases and templates for
‘functionality testing’ makes testing more efficient and significantly reduces cost of
testing
– EAF , a cloud based framework for conducting test automation using open source
tool ’selenium’
– Performance testing service using open-source tool ‘ Jmeter’

What is Performance
Testing?
“It is a testing to determine whether the current system meets the
performance requirements of time sensitive parameters such
as response times and the load of peak or high-volume
processing “.

Why Performance
Testing?
It would be business disaster if the software released to the customer does not
respond within the stipulated times and does not respond well when the
system is loaded. Performance tests are performed to
find out if the performance acceptance criteria are met.
find out if the system/application has any serious performance issues when loaded
provide benchmark figures
find out architectural/design flaws
to find out if the system and the underlying hardware has been tuned for optimal
performance

Performance Testing
Types
1. Performance testing – to analyze software/system response
times when performing different functions
2. Load/Volume testing – to examine whether the system
performs well under the normal specified load.
3. Stress/Endurance testing – to analyze how software/system
performs at peak loads or when it is stressed.

Performance testing
tools
There are several proven tools the industry uses
• HP LoadRunner
• JMeter
• Silk Performer
While LoadRunner and Silk performer are
Commercial (paid ) tools, Jmeter is an
Open source tool. EKA has developed expertise in conducting
performance testing using Jmeter.

Some of the
performance metrics
• Response Time - The time it takes a request to fully load. From the time
the request is initiated until the time it is complete. This generally
indicates the performance level of the entire system under test (web
server + DB). This measure represents the average response time.
• Latency -Time until first response. The time it takes for the first byte to
be received as part of the response. This generally indicates the
performance level of the web server. This measurement represents the
average latency time at a certain minute of the test.
• Users -This measurement represents the number of active users at a
certain minute of the test.
• Hits -This measure represents the number of hits per minute at a certain
minute of the test.
• Errors -Errors generated by the server during the test and errors due to
connection timeouts, refusals or broken connections.
• Bandwidth -The amount of bandwidth used by a request or set of
requests.
• Throughput – Represents the number of requests/business transactions
processed by the product in a specified time duration

Performance test
Analysis
• Analysing test results : During any scenario execution, the tool used for testing the performance records the application
performance under different test conditions. The graphs and reports obtained from the tool are used to analyse the
application’s performance
• Indicated below are samples of reports generated by performance testing tools which are helpful during the performance test
analysis

Performance
Engineering
• EKA makes use of the graphs and charts generated by the tool used for
performance testing to analyze the performance of the system
• EKA then identifies the possible bottlenecks in the system and reports the
same to the client
• EKA also takes up the activity of doing a retest after the system is tuned to
meet the performance requirements

Case Study
Scope and Application type: To carry out load, stress testing and determine end user response time with application under load for a
reputed client on a web based trade deal application
Approach : Eka followed its Performance testing methodology with the use of the tool Jmeter
Project Execution: Objectives tested by simulating different workloads on the application
Observations:
The application breaks down once a load of 98 users is simulated
After 60 users, the application performance values are linearly increasing for transactions
From a performance perspective, the application can handle upto 60 users without any linear increase in response time
Deliverables: Average response time, throughput graphs with detailed analysis of the system performance subjected to increasing load and
number of users.
Benefits to client:
The overall performance testing and analysis carried out by EKA helped the client to scale the system upto 250 users
The client was able to tune the system based on the suggestions given by EKA
