Expert Perspectives on Mobile Performance Testing
TODAY’S SOASTA PRESENTERS
Mark Tomlinson: West Evergreen Consulting, former LoadRunner PM
Dan Bartow: SOASTA VP Product Management
Moderator: Brad Johnson
Agenda:
• Poll question
• Embracing mobile performance testing – what's new and what's
not
• Building a performance test plan to address what really matters
• Testing and measuring for "Fast" and "Strong" all at once for mobile
and web
• Implementing a solution that does it all with agility to match the new
normal
Questions:

3. 3
o Sheer Number of Devices (953M Smartphones)
o Different Operating Systems
o Scale of Global Customers (6B)
o Dynamic Content (Video, Animation, …)
o Emerging People to Machine Interfaces
Mobile performance at scale can not be
tested manually.

5. 5
o Development teams test at a unit and component level (as always)
o Test teams load test with web-based traffic (if load testing at all)
o Ops teams monitor with services built pre-Smartphone
o No one communicates, yet agile dev is all
about communication!

o Performance Guy
o Small tests & Big tests
o Small & Big companies
o …speed freak.

- Old applications migrated to new mobile formats – “transformation”
- New Applications added-on to existing systems – “bolt-on”
- Entire new business units created for mobile consumer experience
- Device manufacturers are investing and expanding – alarmingly!!
- “The number of Smartphone users worldwide is predicted to exceed
1 billion by 2014” (Parks Associates, 2010)
- “Tablets to hit 100M shipments in 2012” (Source: ABI Research, 2012)
“Every customer I’ve worked with in the last 18 months
is prioritizing mobile performance testing.”
-Mark Tomlinson

WHAT’S NEW?
oDevices – lot’s of ‘em
oBattery Life & Heat
oGeographic Diversity
oLatencies – insanely high
oVariable Processor Frequency
WHAT’S NOT!
oThe risks of poor performance
oResponse Time & Volumes
oRoot-cause Analysis
oCapacity Estimation
oTest Planning
oBugs…lot’s of ‘em

A real story about a customer situation:
1.1,000 requests per second into the services infrastructure
2.Systems were fine-tuned, low-latency (< 250 ms)
3.Memory (in .NET CLR) was also optimized with perfection
4.They introduced a new mobile experience to the end-user
5.10% of the company started using the mobile app
6.What happened next…???
YOU MAKE THE CALL…

11. 11
Enhance existing plans for mobile:
• Specific response-time goals for mobile
• Connected/disconnected test scenarios
• Mobile test lab setup & configuration
• Matrix of devices to be tested/supported
• Define end-user location and conditions
• Monitors for device’s physical resources
• Monitor client-side performance
Let’s review an example test strategy…

12. 12
Ensure that new mobile plans include:
• Mobile Performance Objectives (time)
• Defined scope for device types
• Detailed explanation of end-user behavior
• Inter-app test conditions
• Carrier-specific test conditions
• Failure and recovery conditions
• Back-end system dependency and impacts
Let’s review a new mobile test plan…

Measure what
Matters
o Dev teams test early and continuously for FREE with
CTLite
o Test teams respond quickly with complete mobile
coverage
o Ops team validate and tune production infrastructure
