Testing with a post FreeBSD-beta3 build (kfreebsd-image-10.1-0-amd64_10.1~svn272324-3_kfreebsd-amd64.deb), which was build by Christoph (available here https://people.debian.org/~christoph/), still shows performance regressions.
The write speed has improved, still slower than with the old vt, but scrolling up is much too slow. With the new kernel version the whole boot process takes more than 3 minutes. (A recording of the boot process and vt speed is available here: http://youtu.be/0hJMGMP36vE Recorded by me with a mobile phone) Also the new kernel version showed a page fault in kernel space in the Hyper-V driver. (Stack trace was lost, but I assume that is an upstream bug anyway) Oddly enough manually editing /etc/grub.d/10_kfreebsd to include "set kFreeBSD.hw.vga.textmode=1" in the grub config seems to fix these problems. That cannot be a solution though, as these kind of problems should not appear in a out-of-the-box configuration. -- Best regards Jan
