Remote sync slow

[coopered]

Hello
I have setup remote sync with another PBS located on another continent that has a 1Gbps connection. Considering the distance we have a ping around 130ms.

Using iperf a fiber 1Gbps up/down connection only yields 168 Mbits/sec.
And on a fiber 100Mbits up/down connection on different internet provider yields 16.8 Mbits/sec.

proxmox-backup-client benchmark also results in TLS (maximal backup upload speed) of 2.17 MB/s for the 100Mbit connection and 20.35 MB/s for the 1Gbps connection.

Any tips to improve this?
Thanks

Update:
I created 6 different sync jobs and now I'm able to use my full bandwidth if there is no other solution.

that is a general problem with tcp connections over 'high latency' links (see your iperf result)

Using iperf a fiber 1Gbps up/down connection only yields 168 Mbits/sec.
And on a fiber 100Mbits up/down connection on different internet provider yields 16.8 Mbits/sec.

proxmox-backup-client benchmark also results in TLS (maximal backup upload speed) of 2.17 MB/s for the 100Mbit connection and 20.35 MB/s for the 1Gbps connection.

2MiB/s ~ 16MBit/s and 20MiB/s ~ 160MBit/s so that seems to be consistent
