UPDATE: I manually disabled the E cores by adding this to my VMX file: Processor1.use = "TRUE" Processor2.use = "TRUE" Processor3.use = "TRUE" Processor0.use = "TRUE" Processor4.use = "TRUE" Processor5.use = "TRUE" Processor6.use = "TRUE" Processor7.use = "TRUE" Processor8.use = "TRUE" Processor9.use = "TRUE" Processor10.use = "TRUE" Processor11.use = "TRUE" Processor12.use = "TRUE" Processor13.use = "TRUE" Processor14.use = "TRUE" Processor15.use = "TRUE" Processor16.use = "FALSE" Processor17.use = "FALSE" Processor18.use = "FALSE" Processor19.use = "FALSE" Processor20.use = "FALSE" Processor21.use = "FALSE" Processor22.use = "FALSE" Processor23.use = "FALSE" That bypasses the E cores which are the root source of the slowness. My VM now runs on par with the VM on my old machine. I'm still kind of shocked that it isn't running significantly faster.

I am having the same issue. Brand new Lenovo p16, Workstation 17 Pro, 64GB of RAM, Core i9-12900HX running Windows 11 Pro. I copied a VM from my old laptop - a W541 with 32GB of RAM and i7-4910MQ processors, running Workstation 11 Pro on Windows 8.1 - and it performs about half as well on the new computer as on the old computer. It is mind-boggling. The two VMs have identical processor / ram settings, and a simple build of a Java application takes 50% longer on my p16 with 17 Pro than on my W541 with 11 Pro. I have disabled Hyper-V and memory protection and my power setting is "Best Performance." So it is, as you can imagine, extremely disappointing to buy a brand new high-powered laptop and get inferior performance to a much older, under-powered computer on an EOL'd OS. There is very clearly something going on between VMWare and the Intel cores that is hamstringing performance. I hope VMWare can get this fixed quickly, as it at this point makes more sense for me to do my work on my old laptop.
