Well, this is a stand-alone production programmer capable of
programming up to 4 boards at once, it is not a hobby tool.

I assume that you're programming using an Ethernet connection, given the
above, and will be using a 100Mbps connection. All this will provide a
nice fast programming speed, but at a price--$2K approx.
Watch this space. :-)

I bought mine for 1590 Euro, it is not a cheap JTAG tools but it is
good and it worths its price.

Sounds good - how much does it cost?

Thank you for the comments. Good point that we need to look at
verfiication time as well since this in a mgmt box we cant afford stuck
bits.

Michael, I don't have raw rates but only for formatted data transfers
which from memory is about 10 seconds for 4Kbyte boot loader image at
230400 baud. I might do a raw data test to see when USB latencies cut
in as I am sure this depends on the ACK protocol.
The thing that I was surprised was that just to set up the link, and
eraseing a bunch of sectors (using a one IAP call) seems to take as
much using JTAG as it does using serial communiations.
I was aware that JTAG setup costs are high but it pays back in the
sustained transfer rates because clocking speeds are many orders of
magnititude faster than serial baud rates.
I didn't know that setup costs were that high to make serial mode
still viable for small loads, for example if loading just the boot
loaders.

Wow... programming 500KB file gets even faster at about 135 KB/s:

P.S. The test is made using adaptive jtag clock. This is the homepage
