I don't use PMG, just wanted to evaluate if should try it. But without that ability i see no reason to switch from standard postfix + postfix-admin to pmg. Basically postfix-admin does that via mapping. Cheers :-)

Yeah indeed, i wrote non understandable crap :) What i meant was: rama@golima.de -> Kerio stoiko@golima.de -> Exchange lama@golima.de -> Zimbra Routing to Mailserver based on destination email address. Not Domain based. All users are under the se domain. Thanks stoiko :)

Lets do a conclusion, because this thread get too long: Local Storage / PVE Default Settings (Zstd 1thread): ZSTD -> 1GB/s limit LZO -> Around 600MB/s GZIP -> Around 40MB/s none -> 4,5-5 GB/s Local Storage / Zstd: 32 threads + Pigz: ZSTD -> 1GB/s limit LZO -> Didn't tested, but i don't expect...

https://bugzilla.proxmox.com/show_bug.cgi?id=5481 Im not completely sure if it's SSL, but almost nothing else is left. I cannot break the barrier of 1GB/s, no matter which hardware. And im absolutely sure, that no one can, if the destination is a PBS. Alternative way that's left, is to ditch...

Okay, im further in my research, there seems indeed some bug: If i do an iperf3 test from LXC to Node directly: [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 4.44 GBytes 37.9 Gbits/sec 0 434 KBytes [ 5] 1.00-2.00 sec 4.33 GBytes...

Glad god you didn't listened to me xD

PS: i forgot to mention: echo "performance" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor Should increase fsync twice. Thats a dirty hack, but makes it a lot more reliable to test one server against another. Because with ondemand you don't know at which frequency your test was...

Okay, its not ZSTD itself, but a Bug in Proxmox somewhere: https://pve.proxmox.com/pve-docs/chapter-vzdump.html#vzdump_configuration you can set "zstd: 1" I did a test to backup to Local-Storage and indeed zstd runs with 32 Threads!!!! But the Backup-Speeds still hits all the same limits! No...

Actually, lets think different, i can use no Compression, because the files gets anyway Compressed with LZ4 on the Backup-Server, at least via ZFS. But this is still a bummer. That means simply that 1GB/s is the max Backup-Speed Limit for everyone, that don't disable Compression. Cheers EDIT...

Anyone here reached higher Backup-Speed as 800MB/s or 1GB/s ? Maybe thats some sort of PBS limit Its getting weirder! I have created a VM with PBS on another Genoa Server, the measured write speed is 1,5GB/s inside the VM and read around 5GB/s. But thats a ZVOL issue, that im aware of, the...

Lets start with basic tuning parameters that i use: -o ashift=12 \ -O special_small_blocks=128k \ -O xattr=sa \ -O dnodesize=auto \ -O recordsize=1M \ Thats means logbias is default (latency) + special vdev Testings: logbias=latency + special vdev: INFO: Finished Backup of VM 166...

Thats still the only way to delete stupid chunck files, if you need to, lol However, that command will loop through all files and individually touch them, which is a big loop and execution time of touch comes into play either. I have a better idea, to speed that crap up by at least a factor of...

All Samsung Consumer "NVME" drives are pure crap. The sata versions like the 870 Evo/plus are pretty good tho. (in reliability, not iops) But other Brands can be even worse, or better in TBW but with less speed/worse latency. So thats why im using myself something like 970/980/990 Pros/Evos xD...

-> I checked with a script that does: dd if=/dev/zero of=/mnt/$diskid/1m_test bs=1M count=8000 oflag=direct the write speeds for each disk. -> all disks support 4k Locical Block-Size and 512b, but they come shipped by default with 512b. ---> There is absolutely no performance difference between...

War doch das gleiche spiel damals mit darkmode. Solange das Script immer geupdated/angepasst wird auf neue PVE Versionen, passts ja. Die 2 Daten die ausgetauscht werden, sind ja auch kein problem, werden doch eh von PVE ersetzt beim update. Einzige was bedenkenswert ist, ist sensors-detect im...

Das ist ja gigantisch! Hoffentlich wird das integriert in Proxmox direkt genauso wie der darkmode damals, das ist ne absolut wahnsinns Erweiterung. Jedesmal ins ILO/IPMI/IBMC zu schauen um Temperaturen zu erfahren und die scheiss Management interface sind so kake lahm, aktualisieren eine...
