Abysmally slow restore from backup

I can confirm improvement of the verification process. I have increased from 1 read and 4 verify to 4 and 16. The improvement is about 3 times. Maybe I will try to tune it a bit more. Well done to Proxmox team and of course to @kaliszad and his team.

is local restore can be improved by your patch ?
I mean PBS installed alongside PVE where network is over localhost ?

Just to report : even local restore is boosted.
PBS alongside PVE , Restore to Datacenter SATA SSD from Datacenter SATA SSD
170G used data of 400G virtual disk
Speeds are over SATA speeds because writing zeroes seems accounted/
PVE 8.4.0 restore was 630MB/s ( ~11 minutes) ( so real speed was 250MB/s )
PVE 8.4.16 to 1800MB/s ( ~4 minutes ) ( so real speed is the max SATA ~550MB/s )
