i am already using bhyve to run windows 7 guests on one server, all are small guests with 1 or 2 cores allocated. Works fine with good performance. Recently i changed computer configuration in one of my client's office. Before: low end PC as unix server Dell T110-II with quad core Xeon E3 v1 running windows 7 natively After: New server with CPU: Intel(R) Xeon(R) E-2136 CPU @ 3.30GHz (6 cores*2 threads) as unix server with windows 7 moved to bhyve. i run bhyve VM like this: nice -n -20 /usr/sbin/bhyve -s 0,hostbridge -m 22528M \ -H -P -S -c cpus=11,sockets=1,cores=11,threads=1 \ -s 7,fbuf,rfb=10.2.3.4:5900,password=secret \ -s 3,ahci,hd:/dev/ada2p5.eli,hd:/dev/ada2p6.eli,hd:/dev/ada2p127.eli \ -s 5,virtio-net,tap0,mac=08:00:27:b7:ca:16 \ -s 30,virtio-rnd -s 31,lpc -U 0072c755-0e33-11ea-b92a-4c53821d28a6 \ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd -w windows And it runs properly with 11 threads available for windows. But windows feels quite slower that it was before. There is for sure no problem with I/O performance. It's about compute speed. What i do wrong?
