Most Dell Servers are delivered with active powersaving features within BIOS and iDRAC. These often counteract when it comes to virtualization. So set the system to MAXIMUM_POWER. The following 3 values i have in my deployment script... you should take a look wheren it in the iDRAC. Also take notice that the Xeon Silver 4310 is a entry level one and should be avoided when it comes to virtualization and everything which have SAP in its name. A system reboot is needed to take changes effect. Regards,Joerg
Just setup an R450 with an ME5012 (6x3.8TB SAS SSD) connected through 2 12Gb/s SAS connectors and running Server2022.  2x Xeon Silver 4310 CPUs with 256GB of 2666 DDR4 We migrated over one of our 2016 database servers, it's our SAP WEBI BO server, over to it, from an older HyperV system running standard non-SSD drives on a SAN with slower memory and a slower CPU, and it's slower on the new system than the old system despite more CPUs, more memory, fast drives, etc. We've also built up a Server 2022 VM from scratch on it and that is also slower compared to an old VM on an older HyperV server.  The 2022VM runs extracts, on the old 2016 server, the extracts would take 3 hours to run, the new server is well over 5 hours to run. All the drivers are updated, the vhdxs are all fixed sizes, VMQ has been disabled.  The servers used 2x1Gb teamed LAN ports to communicate with the outside world, these are teamed using the new SET team option.  The allocated CPUs are 100% reserved for the VMs, as is the RAM.  We've run Resource Monitor and we're also doing a Live Optics on the VM, and the host, and everything is suggesting that the VM and host aren getting taxed at all in anyway.  The CPUs don't hit 100%, plenty of spare RAM, Hard Faults/sec is 0, Disk Queue Length doesn't get above 1 ever, LAN ports aren't getting saturated, latency on disk reads doesn't even hit 1ms. Anyone ever seen this before?    
R450 with ME5012 sluggish performance with HyperV
