Works for me - copies at (around the sonar test value of) 1.1MB/s to
GLA. Interestingly, the instantaneous rates that gridftp reports for
these transfers are multiples of 512KB/s, which I've not seen before
(the 1.1MB/s is an integral over 512,1024, 1536 and 2048 KB/s
samples). This implies something about the rate limits on the
individual channels bonded to provide our link (probably at the BNL
end) - there are at least 4 links, each rate-limited to 512KB/s.

Works for me - copies at (around 8 times Sonar) 4.4MB/s to GLA (only
one sample here, so...)

Works for me - copies at (20x ! Sonar) 58MB/s to GLA (only one sample
here, so..)

not tried the copies the other way yet...
