Could you elaborate? For example, what happens if we start to sync in ram_save_iterate() for some time intervals (e.g. 5 seconds)? Btw, we shouldn't have this extra sync exist if auto converge is disabled no matter which way we use, because it's pure overhead when auto converge is not in use. Thanks, -- Peter Xu
