I've been told that Firefox limits the amount of processor power that the flash player plugin is allowed to use. That may be your problem. Perhaps it also limits network usage/bandwidth.
I can't confirm this is true but your results seem to point that direction. FYI, FF 3.6 was recently released. Maybe try that to see if they have done anything under the hood to help flash performance. -Jake On Thu, Feb 11, 2010 at 11:08 AM, Lee Jenkins <l...@datatrakpos.com> wrote: > > > Lee Jenkins wrote: > > > > > > Lee Jenkins wrote: > > > > > > > > > > > > Web based flex applications seem to take magnitudes longer to return a > > > result > > > than do Air based application.
