Is 1M additional clients really "overloading". I'd guess they already handle more than 100X that many clients. This is a series question. How many NTP clients are there in the world today. I'd not be surprised if there were a half billion. If so his 1M adds only about 1/2% more. Currently the pool has 2,500 servers. he is only adding on average 400 new clients to each server. that comes to just a few data packets more per minute. OK yes, for sure the load would not spead so evenly but as an very rough estimate e see it is not a huge new load, not with over 1000 active servers in the pool. Wouldn't it be best if he used the pool and at the same time added 6 or 8 of his servers to the pool? That way he is "doing his share" of the work Using pool servers might be moot. We don't know. Perhpas this is a closed "island" network with no access to the outside? In that case his best bet is to build 8 or 10 servers and distribute then amoung his clients and point every client at every server and let NPT sort out what servers are best. I assume no sane person wants to maintain 1M different config files. Make than ALL the same on every client.
