SupportAssist OS Recovery updates almost always relatively slow to download

Whenever I run Dell Command|Update, and it has to download an update for Dell SupportAssist OS Recovery, historically it has been > 200MB and, according to progress messages, downloads at less than a megabyte per second, whereas other downloads are a respectable 10-30 MB/s.  It makes me think there's something wrong with your servers, like they're half way around the world in Japan or something.  In my experience, it's practically the only Dell update which goes so slowly.  Any ideas on how to improve that, Dell?
