94# and any change in the offsets would hint at a bug in the job throttling code.
95#
96# In order to achieve these predictable offsets, all of the following tests
97# use speed=65536. Each job will perform exactly one iteration before it has
98# to sleep at least for a second, which is plenty of time for the 'quit' QMP
99# command to be received (after receiving the command, the rest runs
100# synchronously, so jobs can arbitrarily continue or complete).

102# The buffer size for commit and streaming is 512k (waiting for 8 seconds after
103# the first request), for active commit and mirror it's large enough to cover
104# the full 4M, and for backup it's the qcow2 cluster size, which we know is
105# 64k. As all of these are at least as large as the speed, we are sure that the
106# offset advances exactly once before qemu exits.
