Greetings Listserv admins, We are running Listserv 15.5 and are thinking of employing rate limiting, and are having difficulty picking a number. Here are the numbers we do know: Our largest list, comprising all faculty, staff and students, has roughly 70000 subscribers. After someone sent an 8M message to it we put on a size limit of 1 megabyte. Our VMWare guru (Listserv is running in a virtual machine) tells me that pver the last day the peak outbound SMTP was about 2.5 megabytes per second. This would seem to suggest that the 12 mega-BITS per second given in the example in Lsoft's description of the feature would be about right to cut that peak in half. Maybe even less since it really was an isolated spike. Maybe 8.... However reading further I see that for purposes of this feature Listserv counts the size of messages by multiplying out the number of recipients. Given that the peak our VM guru saw would have been data packed into BSMTP batches of 100 recipients, does that mean we need to multiply that number by about 100?
