Description:
What is performance testing and why should you make it a regular part of your SharePoint projects? We will go through a number of techniques and live demonstrations for how to go about performance testing and some of the tools available to work with. We’ll also discuss some of the experiences from the field of what might be wrong and how those issues were identified and addressed.

Some real life experiences

• Inconsistency– Between 5 and 50 seconds to load a page

• Reliability– Memory leaks causing app pool recycles– Load balancer failures under stress

• Latency– 30+ seconds to load a page at remote locations

• Poor perception– Page ‘blocking’ causing perceived poor performance

What’ the difference?

Performance Testing and

optimisation

Load/Stress Testing

My approach

What • What should I focus on?

Optimise• Get those

things working to where I’m satisfied

Load test• Make sure that

it isn’t going to break under stress

What did we just look at?

• Tools– Yslow– Google Page Speed– Fiddler– Developer dashboard

• Asynchronous calls• Caching– Page Output– Blob– Custom

Load/Stress Testing

• What are we trying to test?– Will the infrastructure ‘break’ under load?– What is the maximum sustained RPS within the

target response time?

Requests Per Second (RPS)• A = Total # of users (1000)• B = Estimated % concurrent users (50%)• C = Average # of requests per day (20 * 10 = 200)• D = Peak ratio (x2)• E = Hours in a business day (8)

• Requests per day = A * B * C * D• Seconds per day = E * 3600 (seconds per business day)• RPS = Requests per day/Seconds per day• RPS= (1000 x 50% x200x2)/(8x3600)• RPS= 200,000/28,800 = 6.94

Tips

• Difference between F5 and clicking a link• Create warm up scripts• Don’t use think time• Keep tests discrete• Visual Studio does NOT execute JavaScript• % of new users

QUESTION AND ANSWER

Respect the Time and Energy of your customers. Don’t forget people that have a high latency link. Make the effort to know what to expect and optimise. Give your users a great perception of performance.

“Don't lower your expectations to meet your performance. Raise your level of performance to meet your expectations. Expect the best of yourself, and then do what is necessary to make it a reality.”Ralph Marston
