Network Bandwidth

A network bandwidth experiment was performed using the following from a bash shell (with and without a VPN running). The rate returned from rsync was multiplied by 8 to get approximate bits per second values.

 cd /tmp
 rm -f kernel*maintainer.tar.xz .
 rsync -v --progress --port=47732 deosftp@deos.ddci.com:/ftp/pub/deos-products/kernel/kernel/stable/kernel*maintainer.tar.xz .

Then run http://speedtest.net to get the raw download speed (upload and ping times from speedtest are not included in the following tables).

And this with a VPN running to get ping times (you have to C-c to end the ping):

 ping deos.ddci.com

The table below shows results for VPN, No VPN, and Raw (speedtest) in Megabits per second. Ping times are in milliseconds.

For the following use the MB/s report from the rsync progress and multiply by 8. For example:

kernel-11.7.0-maintainer.tar.xz
   170,446,008 100%   10.72MB/s    0:00:15 (xfr#1, to-chk=0/1)

so 10.72*8 is ~85.8Mbps

geek	host	VPN	No VPN	Raw	Ping
AL	Linux	85.8	N/A	536	75
