I need to transfer a file between 2 servers, the output of iperf is:

TCP window size: 85.0 KByte (default)
------------------------------------------------------------
[  3] local X.X.X.X port 58986 connected with Y.Y.Y.Y port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec  4.00 MBytes  3.35 Mbits/sec

I am using netcat with something like this from the origin:

pv 100GB.file | lz4c | nc Y.Y.Y.Y 9999

And in the target Y.Y.Y.Y host:

nc -l 9999 | lz4c -d -| pv > 100GB.file

With this method, the max speed I can get is:390KiB/s

Any idea of what protocol or method could I use to get speed like when using iperf ~ 3MiB/s

have you tried to uncompressed transfer? reync and scp can do the same – djdomi Jul 10 '21 at 19:43
using `rsync -aHAXxv --numeric-ids --delete --progress -e "ssh -o Compression=no -x" user@host:/100GB.file .` I am getting ~ `382.29kB/s` – nbari Jul 10 '21 at 20:05
rsync does not use Compression by default, and please read my first sentence from my first post – djdomi Jul 10 '21 at 21:57
hi yes, the same thing compressing or not compressing – nbari Jul 11 '21 at 09:08
use screen and let it run ;) it looks to me for a limitation of bandwidth – djdomi Jul 11 '21 at 09:57
