Performance

The Mobile Environment

All Unique!

How we plan Perfect 3G|4G.. Interference?

Reality Bites….

• 2g downgrades are common• RF Interference• Bandwidth Thieves

Resource Locks Slow Connections hold onto to resources longer on

the server A smaller population of slow clients can exhaust a

server faster than faster clients

Purchasing Performance Insurance

• Performance Engineering & Performance Testing• Improve your test network• Production Slow Lane•Data Flow Management• Know your users!

Performance Engineering

•Get Involved at the Design and Development stage• Be the voice of reason for increasing the size

and number of data flows• Catch changes in performance at the Unit,

Component Assembly and Functional Test stages.• “If it doesn’t work for one, then it will not scale

to many”

Test Network Improvements

• “Get Dirty”•Drive around. Go to crowded and RF noisy

places to test• Add impairment. Increase the errors and

reduce the speed•OOKLA (Speedtest.net)• Tools: WanEM, HP Shunra, Ixia, Spirent

Production Slow LaneWWW.mysite.net

m.mysite.net

Have a Dedicated Resource Pool for resource hogs – like slow mobile users

Don’t forget tablet’s connected by cellular which may be connecting to your desktop servers

Leverage your GEOIP Providers (such as maxmind) and their ability to provide data on type of network connection as well as location

Data flow management

• The smaller and fewer your data flows are the more responsive your application will be over a slow or congested network• Force a justification for every extra inclusion in content and

number of stylesheets, JavaScript files, etc… • Manage your cache effectively on both the client and CDN to

reduce resource lock on the server• Don’t ship with 404’s!• See Steve Souders, “High Performance Websites”

Knowing your community

• In a blended environment make sure you have the appropriate mix of mobile and desktop devices in your performance test load model (with impairment). •Make sure you are planning for growth in the

mobile community of users with hard data from your site for 12-18 months out.
