1. [SOLVED] Random access speed slowdown in Nested Proxmox

    Hi. Please take a look at the image comparison first. I ran Crystaldiskmark on a bare metal Proxmox and a nested Proxmox. The storage random access speed is clearly lower on the nested. What could be the cause of this? I imagine it is the block size. Memory cache is set to "none". Any Idea?
  2. Problems following proxmox documentation about ZFS benchmarking

    Hello everybody, I want to benchmark my ZFS pools in a server that it's already running with data (mostly testing, but I don't want to lose it). For that purpose I have found =278bafe4f7648fa8072a76aebfd271e2']this, a ZFS benchmark done by proxmox team. So it looks like a great fit. They are...

  5. [TUTORIAL] Write Amplification Benchmark Results

    The last weeks I did 172 benchmarks to find out why my write amplification is so horrible and to see what storage setup might work better. In this thread I will try to summerize all the tests and explain what I learned so far. Edit: Will post link when finished.

  8. Basic IO benchmarks between zfs/lvm-thin/qcow2

    Just ran these the other week, thought I'd share. I'll try to do some more proper ones on Linux, but before that happens here's some CrystalDiskMark ones on Windows 2019 (virtio-scsi). The underlying storage is a single Samsung 850 PRO SSD. I was pleasantly surprised by the QCOW2 performance...
