My Unraid system is very slow. I sometimes have transfer rates (via SMB) of a few MB/s when writing to the NAS, even though I use SSDs exclusively. My system: i7-10700k (underclocked) 64GB DDR4-3200 NVMe: 2x WD Blue SN570 1TB SSDs: 2x WD Red 1TB, 1x WD Blue 1TB, 1x SanDisk Ultra 1TB Unraid 6.12.2 stable One of my NVMe SSDs is the parity drive, the others are for data. Using FIO, I ran various benchmarks. The read speeds are at 250-550MB/s for the SATA SSDs and 3100+MB/s for the NVMe. Running fio --rw=write --name=test --size=500M in the /mnt/disk directory of a SATA SSD the results are normal, with speeds of 250MB/s, the same for the NVMe with 2200MB/s. But when I use the same command with --direct=1, which enables Direct I/O, I have write speeds of 2-10MB/s on the SATA SSD and 30-60MB/s on the NVMe SSD. This sometimes results in very slow write speeds when copying data to my NAS via SMB. This issue is not new to me, so unrelated to this Unraid Release. The attached text file shows the benchmarks using FIO on my SATA and NVMe drives with Direct I/O enabled and disabled unraid_ssd_perf.txt

Same issue here. I have 3 VMs running (Debian, Macinabox and Windows Server 2019) and when i go to the VMs tab it loads the Web page, but the VMs list is empty and loads forever. If I try to leave the page, no other page loads as well, making the Webinterface inresponsive. However, I can still control the VMs from the Dashboard if it decides to load someday. I found a "fix": abort website loading, open the login url of unraid and sign in again. WebGUI works (as long as you avoid the VMs tab) Unraid 6.10.0-rc4 towernas-diagnostics-20220503-0917.zip
