    Standard VirtualKD installation does not work in latest Win10 builds (probably starting from 1903). The installer creates the “dbgtransport” BCD value equal to “kdcom.dll” (kdcom.dll is the kdbazis.dll renamed). Deleting this value and creating “debugtype” = “serial” solves the problem.

    These PF’s are not paging ones (pagefile size is fixed to be 16 Megabytes, just to create crash minidumps). There always are 1-3 Gigabytes free but VMMon always produces hundreds or thousands PF’s per second.

    Tested with a hardware 1394 connection and XP/Win7 systems – in multiprocessor mode, string output it more times (5 kB/s vs 280 kB/s) slower than in uniprocessor (with ONECPU) mode.

    So VirtualKD does not affect string output speed. I’m afraid Windows uses a kind of all-CPU synchronization method for string output.
