4.5Mbps down and 2.5mbps up - capacity?

[Rhodan]

I've done some of those internet speed tests and tried to mix up the locations (hard to know exactly where they are) and my average connection speeds seem to be 4.5 megaBITS down and 2.5 up (bits, not bytes). Thats close to 0.6 mBytes per down and 0.4 mBytes up.

Assuming a big raid all in one zone, how many clients do you think this could handle without the server introducing lag/LD? No telling which clients couldn't handle the throughput so just assume they can all handle whatever the server tosses at them.

Not planning on going public, just wondering what it could do. Thanks!
