GPIB Ethernet/100 Performance

Does anyone have some real world peformance measurements on the transfer speeds of the NI GPIB-Ethernet/100 box. I am very disappointed in the performance of a block read which is approximately 6ms/byte transfer (tested from 20 bytes to 32kbytes block transfers). This is on a 100 Mb Ethernet. I can ping the box with 64 byte round trip transfers at ~0.7ms/packet.
I almost feel that the GPIB-Ethernet Box is not buffering my GPIB transfers.
Thanks

Actually ignore my question. My transfer speeds are ~6 microseconds/byte (not milliseconds!). This is still a little slower than I would like, but not totally unreasonable! Note the vertical axis in the included plot (pdf) is in ms, so the linear coefficient in the fit equation is 13 microseconds/(16 bit word).
