Backup slow

[mechanicus]

My backup seems to be slow. The speed is only 10 MB/s.
Here is the log file:

Why is there a bandwidth limit of 10240 KB/s?

My proxmox version is

# pveversion 
pve-manager/1.5/4728

and the performace is good:

# pveperf 
CPU BOGOMIPS:      37238.68

It works, thank you.
But in the created /etc/vzdump.conf I have to write "bwlimit: 80000" instead of "bwlimit=80000" suggested in the thread.

Best Regards
