You’ve probably thought about the speed of your servers running your business intelligence (BI) workloads. But what about your client devices? Choosing the wrong mobile platform can impact performance when running reports on client devices and leave you without key functionality.

What kind of impact to performance? We put four devices to the test to find out:

  • Lenovo ThinkPad Yoga
  • Lenovo Miix 2
  • Apple iPad Air
  • Samsung Galaxy Note 10.1

For the workload, we used IBM Cognos Enterprise software; it is both widely used and supports large workloads.

Faster IBM Cognos BI Reports with the Right Tablet

The ThinkPad Yoga and the Miix 2 displayed reports an average of 3–7x faster than the iPad Air or the Galaxy Note 10.1 in Prowess testing.

Depending on the data set, reports generated with IBM Cognos Mobile on mobile devices based on iOS or Android can take upwards of 20 to 30 seconds to generate. For a single report, this difference can be minor, but if you need to view several reports in a rapidly moving discussion, the delay can impede the flow of the conversation.

By contrast, the ThinkPad Yoga and the Miix 2 produced reports in as little as three to six seconds in Prowess testing, even for very large data sets.

But Wait, There’s More: Cognos on Windows 8.1

When you access Cognos Enterprise from mobile devices running Windows 8.1 (such as the ThinkPad Yoga and the Miix 2), you can create new reports beyond those already created in Cognos. But web browsers and Cognos Mobile apps that are available for Android and iOS devices (the avenues for accessing data on the Cognos server), do not support creating reports outside of those already available in Cognos.

Cognos Mobile apps for the iOS and Android devices can only generate reports that are defined in Cognos Workspace Advanced, but cannot access Cognos Workspace Advanced to create new reports or alter existing ones. This limits the questions you can ask of your data on iOS and Android devices.

Stay tuned for the paper with the full results of our testing. Also, see how upgrades to software and hardware on the server side can impact BI performance.
