fstrankowski replied to the thread Network Optimization for High-Volume UDP Traffic in PVE.Have the tests been performed without any interfering L2/L3 equipment between VM and Client? If not, how did you rule out its not the networking equipment inbetween? -
Kkosnar replied to the thread Network Optimization for High-Volume UDP Traffic in PVE.My tests were made with default = 1470B packet size. Measured limit is 250566pps. I guess in my case the limit is single-thread CPU performance. Using multi-thread in iperf I get 5.95 Gbits/sec 505548 pps but with high packet loss 16% - this...

JJoe77 replied to the thread Langsame 4k Performance in Windows 11 VM.Das sieht bei meiner VM deutlich zu lansam aus. Auf meinem Desktop PC der schon einige Jahre alt ist ist es auch deutlich schneller. Ich stelle mal den Prozessortyp auf V3 und teste. Wobei ich doch auf das Storage tippe.

KKhensu replied to the thread Ceph - Backfill & Remapping processes will not finished.Hi @Quasar90, you are welcome. It was fun exploring the ceph docs regarding this behavior :) The fact that CEPH is healing itself here confirms my previous statement. That was probably just the balancer and the 5% limit, which took some time...

QQuasar90 reacted to Khensu's post in the thread Ceph - Backfill & Remapping processes will not finished with Like.
Hey, the 5% sound heavily like the default target_max_misplaced_ratio value. Can you check with: ceph config get mgr target_max_misplaced_ratio Not sure if the autoscaler (Which you disbaled) is at fault here, check ceph osd pool ls detail...

KKhensu replied to the thread [SOLVED] Windows Server 2025 Event Log Service fails to start and Explorer crashes repeatedly.Hey :) glad to hear you figured it out. You won't notice a performance degradation by using v3 honestly, AVX-512 is heavily specific. (Well, depends what you are using the VM for) I also don't think this is a compatibility issue. I think...

JJoe77 replied to the thread Langsame 4k Performance in Windows 11 VM.Mit dem trägen Verhalten von Lexware bin ich eben am suchen.

SSultanOFF replied to the thread [SOLVED] Windows Server 2025 Event Log Service fails to start and Explorer crashes repeatedly.Hello, So! I tried to create a VM with your configuration and, like magic, everything works correctly! I managed to narrow it down to the virtual CPU type.
