Live dynamic streaming (rtmp) very high live delay

Hi,

I'm testing live dynamic streaming with FMLE & FMS 4 & FLVPlayback 2.5 in Flex, and it works, BUT very slow. The connection time and the live delay is too high (30-60 seconds). The bufferTime 3 seconds.

This is normally or not?

On the FMLE the bitrates 50,300,500 Kbps. My net upload speed 2 MBit and the PC is Core I7 (4core, 8Thread) 1,6, 4GB RAM with WINDOWS 7 64Bit.

The FMS 4.0 works on a Blade with 4core, 8GB RAM.

Thank's!
