These tests demonstrate that the new generation Windows Mobile 2003 devices are a superior platform compared to the Pocket PC 2002 for developing and deploying business applications using the Compact .Net technology. Special thanks to MVP Alex Feinman who created the tests.  You can perform your own testing by downloading the test program and source code from Alex's website.  Feel free to e-mail me the results and I'll add them here.

Notes:

  1. Lower is better

  2. All times are quoted in ticks

  3. Up to a 10% variance can occur between successive runs

  4. SQL Server CE was installed in RAM on all devices

  5. Compact .NET Runtime was installed in RAM on Pocket PC 2002 devices

  6. Compact .NET Runtime is in rom on the Windows Mobile 2003 devices

  7. No other applications were running in the background

Tests - Scope

Scenario 1: Loading XmlDocument from an xml file. This primarily tests performance of XML Parser when loading a document without known schema
Scenario 2: Selecting rows from a DataTable. Tests DataSet operations
Scenario 3: Populating ComboBox by setting its DataSource to a DataTable
Scenario 4: XML getElementsByTagName operation - a basic XML query. Tests XML parser
Scenario 5: SQLCeCommand.ExecuteReader call - performs a select query on a 500 row table without indices, that returns int, double and string columns
Scenario 6: Adding new controls to the form and repositioning all existing controls at the same time. Very slow when it reaches 30+ controls

Why is Windows Mobile 2003 Faster?

Overall I believe that the increased speed for the Windows Mobile 2003  is attributed to the new core operating system of Windows CE 4.2 and the installation of the Compact .NET framework in rom.  Further I believe that the cache size of the CPU and the ram bus speed greatly influence the performance as well.  So if you are developing applications using the Compact .NET Framework, I suggest that you use Windows Mobile 2003 Pocket PCs whenever possible.
