Max speed?

Hi,

I am using the PCI-Bridge configured as guest in a Xilinx FPGA.
The Wishbone Slave Unit of the PCI-Bridge core reads data from the memory
of the computer, this is DMA.
The maximum speed I am getting is about 30 Mbit/s. When doing burst reads
cycles with the signals bte and cti the speed is even less. I observe I get
short bursts, about 4 dwords, and lots of retrys.

Any advice or suggestions on how to speed up the transfers would be
appreciated.

Thanks,
Robert
