Thanks for the info/tips. Yeah, so that's interesting, there's not much difference with how I'm running it other than blocking/non blocking and outputting an EPR file or not. Any ideas? Here's what I'm doing, and it's between the same two systems:
1) globus-crft -c -s -m -vb -P 32 -tb 512K -ef status.epr -f xfer.file (goes really slooooowww) versus 2) globus-crft -ez -P 32 -tb 512K -f xfer.file (150-200MB/s) The performance drop I'm seeing is from the area of 150MB/s - 225MB/s ground-down to may be as low as 10s of KB/s to upward of 400KB/s, it also seems to transfer in fits (stops, xfers, stops for another bit, etc.) Thanks!
