Genius! That worked. Who could have guessed this (but a programmer). Thanks to HailStorm!

RIM software development or their purchased software libraries are extreemly inefficient when writing updates to the "Synchronization Progress" pop-up window. I have two different computers and the results are the same. Here are the details of my test
- Verizon Blackberrry Pearl, Phone software: ( I've tried 3 different software version and a completedly new Pearl with the same results).
- Desktop Manager: (I've tried multiple versions, with old versions 4.3 working fine but newer ones, 4.5, 4.7 showing the slow behavior).
- I have 1,400 contacts, 600 calendar items, 200 tasks in MS Outlook.
- PC 1: HP Compaq 6910p, Dual core, 4 GB RAM.
- PC 2: HP Pavilion 763n, Single core (2.5 Ghz), 1 GB RAM
- MS Outlook 2003 (office SP3).
- I repeatedly (6 times) sync with no changes on either the Blackberry or MS Outlook. Thus no updates are needed on either side.
- I use Process Explorer v10.21 to watch the behavior of Desktop Manager (DM), cpu, memory, etc.)

A) When I run the the sync normally, so I can see the "Synchronization Progress" window, it takes 4.5 minutes CPU is very busy (90% +). This is excruciatingly slow. About 10 times slower than the older DM v4.3.


B) When I run the the sync AND ICONIFY the main window, "Working - Blackberry Desktop Manager" and the pop-up window, "Synchronization progress", it only takes 50 Seconds and the CPU is less busy (75%). The sync is 5 times faster when I iconify the "Synchronization Progress" window!.

I am a software developer, and this tells me that the software algorithm (and/or software libraries) used to create/update the "Synchronization progress" pop-up window is very, very inefficient. It is a poor design and implementation when a simple progress bar and item counter take so much CPU that they slow the real work (synchronization) by 500%!

RIM, please get this fixed. It should be trivial.
