JTAG UART slowness

Hi All, I am trying to write a file from the PC into SDRAM through the JTAG UART, and have found that it is quite slow. I only see about 1KB/s, and need to transfer files that are about 10-20...

I see that when I download the elf file speeds of 60KB/s are reported. Assuming that's true, then I don't think its my byte-blaster or cable etc.

All benchmarks have been most likely made with an USB Blaster. Byte Blaster is considerably slower due to the bit-banging method of generating JTAG signals.
