no, problems exist with smaller amounts of RAM. with 16GB guest it is
trivial to get 1s stalls, 64GB guest, 3-4s, with more memory, migration
is flaky to say the less.

the problem here is that we are forced to walk the bitmap too many
times, we want to do it less times.
How much time is spent walking bitmaps? Are you sure this is the problem?

default values and assuming 1Gigabit ethernet for ourselves ~9.5MB of
dirty pages to have only 30ms of downtime.
1Gb/s * 30ms = 100 MB/s * 30 ms = 3 MB.
