Switching in workspace between any item to Emails takes 45 seconds for mail to display.

Question

Have a blackberry Q5 on OS10.3. via BES 12.  When switching between items in workspace it takes 45 seconds to switch and siplay mail in corporate email account.  Any switching between other items is instant.
Device has been replaced twice.
device has been reloaded and also used OS 10.2
User account on BES server has been created on BES 12 server.
This only happens when you switch to look at your emails.  Other than that, the device is working.

Hi Andy,
The switching time depends on the client buffer state and the keyframe interval of the content.  The switch is not complete until it is visible to the user, meaning the buffer has to play through.  So if the client has buffered 15 seconds of content, it will take around 15 seconds to make the switch.  This also depends on your FMS settings since keyframes can be generated on the fly.
This is easy to monitor if you turn on logging for the OSMF Flex project.  You'll see something like this in your log:
Calling for switch to 4 at 1708 kbps
Switching to index 4 at 1708 kbps
event.info.code=NetStream.Play.Transition
info.code=NetStream.Play.TransitionComplete
Transition complete to index: 4 at 1708 kbps
The "NetStream.Play.Transition" means the server has acknowledged the request and has begun the switching process.  The "NetStream.Play.TransitionComplete" is an in-stream event and this means the switch is visible to the user (the buffer has played thru and the new bitrate stream is now viewable).  The time between the "Transition" and the "TransitionComplete" will be very close to the size of the current buffer.  I don't belive we are logging the current buffer size right now, but you can easily do that in your player by getting to the netStream object via the LoadTrait (in sprint 10, sprint 9 will be the loadedContext). There is another thread here about getting to the netStream object if you want to try this yourself.
Hope that helps,
