scp Counters seem to freeze


I'm using cygwin 1.7.7 on a Win2k3 R2 system. When I scp a file from a remote host running RHEL 4.7, e.g.:

Administrator@sm-i222 /cygdrive/d/somedir

scp root@linux_host:/someotherdir/some.file .


The percentage, transfer amount, rate and transfer times all start out registering in the cygwin console window. The rate seems very low/slow. Then when the transfer reaches somewhere in the amount of 10%, all the counters seem to lock/freeze at their respective rates/amounts.

When I open another terminal window on the cygwin system, I see the actual file size increasing in the target directory. Indeed, it looks as if more data had been transferring faster than the counters showed. The link between the two systems is via a 1GB copper switched fabric. That is 1GB NIC's in each system going through 1 GB ports on a Cisco Switch.

The scp does appear to complete as the counters will suddenly go to 100% and when I ls -al the ../somedir/some.file on the cygwin host will show the same correct byte counts between the source file and the target file.

Is this normal behavior? When I do a linux to linux scp, the counters work correctly. Should I expect this from the cygwin scp?
