[Dmitri Bachtin <845775@xxxxxxxxxxxxxxxxxx>]

Thank you very much for filing this report and making Ubuntu better!

It used to be that a megabyte was 1024 kilobytes and a kilobyte used to
be 1024 bytes. Nowadays a mibibyte is 1024 kibibytes and a kibibyte is
1024 bytes. On the other side a megabyte is nowadays 1000 kilobytes and
a kilobyte is 1024 bytes. If you will look at your screenshot, you will
notice that the shell refers to MB (megabytes) and g-s-m refers to MiB
(mibibytes).

The shell reports 4.6 MB/s. That is (4,6 * 1000 * 1000) / (1024 * 1024)
~= 4,4 MiB/s.

Technically, both applications are right and therefore I have to mark
this entry as Invalid. It will take time until one of the conventions to
define size will win.

In spite of that, please proceed contributing to Ubuntu. The only thing
I can offer is a laugh: the good old 1.44 MB floppy storage size
consists of 1.44*1024*1000 bytes ;)

If the root of the differences between the values isn't due to MB and
MiB, feel free to reopen this ticket.

Title:
  gnome system monitor shows network upload speed that is inaccurate

Status in “gnome-system-monitor” package in Ubuntu:
  Invalid

Bug description:
  when transfering a file from local to remote host via eth0, rcp shows
  a transfer speed of 4MB/s.  Checking /proc/net/dev confirms a transfer
  speed of about 5MB/s, and calculating the transfer rate from the ETA
  and filesize confirms a transfer rate of about 4 megabytes / second.
  However, when rolling the mouse over the network window of the gnome
  system monitor shows a speed of about 1/5-1/10 of that reported by
  /proc and rcp (or scp) of about 500 KB/s.

  gnome-system-monitor version 2.28.1-1ubuntu1 on Ubuntu 10.10

  thanks,
  Peter
