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...

Thanks for the information it was very helpful. I mis-spoke in my earlier message. I'm actually using the USB Blaster. An old habit of calling it the byte blaster. I took dwh's suggestion and used the JTAG to Avalon MM Bridge instead of the NIOS, and used the write_master_memory command which speeded things up significantly. I now see ~100KB/sec which is good enough for my purposes. Thanks again.
