PERFORMANCE

matters more than ever before

Social media is highly viral and drives massive amount of

traffic.

#1

500 million active users spending 700 billion minutes per month

13 million hours uploaded in 2010

2 billion video viewed per day

106 million accounts

10 billion tweets in 2010

Web Architecture is complex

Content is king

of consumers say speed is more important than functionality 39%

Expect a web page to load in two seconds or less 47%


Will abandon a web page if it takes more than three seconds

to load 40%


Low performance and unreliability brings

MASSIVE BUSINESS IMPACT

#6

PayPal down 45 minutes in 2009 $45 Millions lost revenue

Amazon loses 1% of their sales for each 100ms of latency

Google loses 20% of search traffic every 500ms of additional latency

60% of companies admit that they do not have any performance management processes in place or what they have is ineffective.

50%

Of companies having performance management processes admit that they are doing it only in reactive way when problem occurs.

50% DynaTrace study- 2009

of application problems are found in production – when those problems have impacted end users and are most expensive to resolve.

What is required today to test effectively

performance of web applications?

SCALE #1

Real time analysis

of performance data

#2

SPEED

#3

AFFORDABILITY #4

Ready for some pain?

Traditional Performance Testing doesn’t work anymore

PERFORMANCE TESTING

REVOLUTION

“ The massive resources of the cloud have changed the game for performance testing. Cloud Testing enables organizations to test their consumer facing Web and mobile applications fast, affordably and at scale. There’s now no excuse for the type of Web site disasters we’ve seen in the past that cost businesses millions in revenues and perhaps more in reputation. ”

Tom Lounibos CEO SOASTA

Objective Identify Breaking Points

Project Length Five Days (non-consecutive)

Staging Lab

Lab

•  First test cycle in the lab •  239 hits per second •  40.5 MBit/second bandwidth

•  Some servers hitting 100% CPU •  Bottleneck in throughput


Lab

•  Second test cycle in the lab •  Higher concurrency target •  Bandwidth stayed the same

•  Some servers hitting 100% CPU •  Performance problem over time •  Load balancer flapping servers


Staging

•  Bandwidth (238Mbits/s) – ouch! •  CPU at 100%


Staging

•  767 Home pages served at 650 megs total transfer. •  That’s an 850kb page weight! Yikes!


•  Poor throughput on the initial tests •  CPU hits 100% •  Bandwidth cap identified in the lab •  Database connections leaking over time •  Load balancer dropping servers

•  Massive page weight on the home page •  Application unresponsive at ~2000 users

•  Customer happy with the breaking point identified •  Optimized web assets in the home page •  Offloaded assets to the CDN •  Load balancer algorithm optimizations

Real-time collaboration

Continuous performance testing

Cloud Testing helps companies

•  Every day at noon is a holiday spike in traffic.

•  Pages must render to the user in under 1 second.

•  50% of all revenue from Gilt sales comes in less than 1 hour after sale starts.

CHALLENGES Testing SOA in the cloud

It gets crowded

Loose SLAs

Harder to predict

(slightly)Different strategy

Same challenges • Services with no user interface • Data driven • Services outside the organization/cloud • End-to-end scenario • Test ownership

Same Bottom-up performance testing approach • Individual services • Set (integration) of services • End-to-end

Deal with Cloud unpredictability • Varying performance encourage continuous performance testing/monitoring. • Infrastructure upgrade could impact performance. • Expect to baseline on premise application and run benchmark in the cloud

after migration. • Test the full bottom-up cycle for increased confidence.
