Hi!
Sorry...
Can you explain why gzip --rsyncable doesn't get rsync speedup?..

I have Proxmox hosts. And I have backups of my VMs like *.gz made with gzip
--rsyncable. And I expect some speedup when i rsync my backups to another
host. But I haven't any speedup...If i try to copy whole file by rsync i
have network speed around 50 MB/s. If i try to copy file by rsync with
--fuzzy or --inplase or to exactly given filename i have 5 MB/s and have hi
load from rsync process to CPU core so i think rsync try to use his
algorithm of delta. But speedup =1. Maybe you know what's wrong?
