<p>How many times slower we expect checking transactions after the last checkpoint to be (from checking signatures, which is skipped up to the last checkpoint). This number is a compromise, as it can't be accurate for every system. When reindexing from a fast disk with a slow CPU, it can be up to 20, while when downloading from a slow network with a fast multicore CPU, it won't be much higher than 1. </p>
