Should we also rename 'MigrationInfo' to 'MigrationRamInfo', so that we don't make a similar mistake in the future of putting a stat in the wrong category? > What do I want to know: >=20 > - is there any stat that you want? Once here, adding a new one should > be easy. Should we have some sort of stat for the number of pages that are sent more than once, and/or for the maximum count of times that a given page was sent? Having hot/cold page analysis might make it easier to decide in the future which pages to avoid sending until the very end, and knowing how many pages are sent multiple times as well as the maximum times any one page is sent might help. >=20 > - examples are not done, waiting until people agree with what params > are needed.
