[Qemu-devel] [PATCH V2 1/4] net/colo-compare.c: Add checkpoint min period to optimize performance |

If colo-compare find out the first different packet that means
the following packet almost is different. we needn't do a lot
of checkpoint in this time, so we set the no-need-checkpoint
peroid, default just set 3 second.
