[flexcoders] ExternalInterface IE performances

[ecpmaz]

Hi, 

I am developping an application using the ExternalInterface API a lot
(well not sure anymore..). But after a few runs a noticed huge
performance differences between IE7 and FF2. I decided to quickly
benchmark them ; here are my results.

100 calls : FF=30ms, IE=1600
1000 : FF=200, IE=3200
10000 : FF=5000, IE=40000

results are quite variable but IE is always way higher than FF...

Are there any plan to improve this API in IE ???

here is my simple benchmark code =============
