description |
I describe the issue in few steps below.
1.) I want to transfer files from machine A (with ubuntu 11.04, but this is not important) to machine B (ubuntu 10.10; this is important to say) using scp.
2.) Machine B is under constant computational load due to a user program (a simulation) such that most of its CPU power is consumed by the program but it uses less then half of total (12 GB) memory and there is not any significant usage of disk and no other application is running. (Even no user logged into a GNOME session.)
3.) I issue the command scp on machine A; I immediatelly get prompt to give password. However the transfer does not start immediatelly after that. I must wait for some time, say half a minute or even full minute or more (I have not measured it.) just to see the start of the tranfer.
Few additional remarks:
Until recently machine B had had installed ubuntu 10.04 (Lucid Lynx, 64-bit) and there was no such problem even at higher computational loads. Similarly there was no such problem even in more distant past when the machine was running under Linux Mint Helena (based upon Ubuntu 9.10).
The long delays when doing scp 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 when.) If an scp transfer is finally accomplished then I can start a new one which already works without delay.
Machine B is equipped with an Intel i7 CPU, 12 GB of DDR3 and it is a quite powerful workstation. All cores of CPU are set to run at maximum frequency.
I attach a file with content shown by the program top. (Grabbed in situation when a user is logged into GNOME session.)
