[PVE-User] Vzdump with and without pigz

[Gilberto Nunes]

Hi there

I am trying to gain some performance enhancement into vzdump, so I change a
feel options in /etc/vzdump.conf.
Without pigz and bwlimit flags:

Time 00:17:06
Size: 22.26GB
Disk image: 30GB
Backup in NFS Server

With pigz set to 4 and bwlimit set to 100000

Time 00:17:18

With pigz and bwlimit it's not suppose to increase the performance or I
miss something?

(My server has 24 CPUS, 2 sockets)

Thanks

Without pigz do you then use gzip or the default lzo? Otherwise you
compare apples to pairs.

To be able to compare you need to use gzip.

With gzip takes 00:21:51

First time I use pigz I have 00:08:42.

I don't know if in the 2d, 3th and 4th time there's some dirty cache
whatever!
