Comment 3 for bug 782092

Clint, I can now answer your questions, at least partially.

* If I renice the program, the effect is likely gone. However, I will be sure only after a longer period of testing.

* Other programs run swiftly (also without renice-ing prog.x).

I will comment on this issue sometime next week or so, as soon as I acquire more evidence. It may be useful to remind the following info from my orginal report:

The long delays in scp procedure occur if machine B was NOT exposed to an scp or ssh demand for a longer period of time. (Typically I face the problem in the morning.) If an scp transfer is finally accomplished then I can start a new one which already works without a delay.
