QEMU/KVM - openSUSE Tumbleweed KDE - EXT4 VS BTRFS

KVM testing on openSUSE Tumbleweed KDE 20241208 via the Phoronix Test Suite. Testing the performance of the different filesystems BTRFS and EXT4. Note, BTRFS is configured without encryption nor compression. Both systems have a single root partition and no separate partitions (e.g. home). Both VMs have the same minimal KDE setup, as well as OpenGL, 3Daccelaration, and CPU-passthrough enabled. The VM manager used was Virtual Manager (virt-man).

Compare your own system(s) to this result file with the Phoronix Test Suite by running the command: phoronix-test-suite benchmark 2412105-TSUK-241209420
