Hi,
i have two servers, connected to to the lan by 10Gb with 10Gb and DAS hardware raid.
Each system con read and write locally or to the 10G iscsi by more than 200 MB/s.
Now I have to transfer backups form A to B and doing this with rsync always stuck at +- 48-50MB/s no matter which options, compressions, encryption etc I use. Even the plain default rsync is at that 50 Mb limit.
coyp by scp goes up to 200 MB/s.
Copy from and to my workstation with scp from or to both servers is at 1Gb limit (so +- 100 MB/s)
Why is rsync stuck at +- 50 MB/s ? Any suggestions hints ...
Thanks and regards . Götz
