No benchmarks done yet, so any performance gains are only theoretical for now :) pve-qemu gains a new build-depends on 'liburing-dev' - this package is available in Debian bullseye, but there seems to be some dependency issues with our pve-kernel-libc-dev package. For now, testing was conducted by building liburing from source, i.e. clone 'https://github.com/axboe/liburing' and run 'make-debs.sh'. pve-qemu: Stefan Reiter (1): enable io-uring support in QEMU builds debian/control | 1 + debian/rules | 1 + 2 files changed, 2 insertions(+) qemu-server: Stefan Reiter (1): enable io-uring support PVE/QemuServer/Drive.pm | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 2.30.2
