IORD_ALTERA_AVALON_PIO_DATA to slow?

Hi, I'm trying to capture samples from an A/D Converter and streaming them onto a PC via an ethernet connection. I've extended the triple speed ethernet design example from the Nios II v9.1 instal...

The amplitude range of the 10kHz is also a different one to the 1MHz signal. Maybe this is something the ADC does?

@Cris72: You are right about the fruequencies. It's always messed up when the signal is over 100kHz. Yes, I use a TCP Stack (Nios II Niche Stack), but to me that seemed to be working fast enough using 1000Mbit/s-Ethernet connection.

So, how could I optimize the design? Is it more a matter of hardware components or my Nios II software?

Would writing the loop in assembler make it fast enough? In the end I want to capture a base band RF signal, don't know to which frequency that will be going...
