[mobile-devel] Bible Text Rendering Speed, SR Beta 1

[SonWon]

Yes, dig up those logs we need to boast the speed of the reader.  if we 
could fetch a single chapter I think that may help.

Although, what is happening in the SR while the progress bar is on the 
screen?  Can u give a high level overview.  Is it rendering to the 
control or fetching stuff from Sword plus rendering?  Lots of questions, 
I wish we could see where the CPU is spending all of the clock cycles on 
this device.
