     Earlier versions ran borderline with about 25k users from reports I
heard.  5.0 has more efficient I/O but more overhead per command, so maybe
more, maybe less, I don't know.  Obviously it all depends on the system you
run it on; I remember Services on EsperNet having lag trouble on startup
with just 700 simultaneous users, but at the time it was running on a
486/100.  Give it an Athlon 1900 or some such and maybe it can handle 100k
users, I don't know--but to be honest it's not really designed to handle
that many users efficiently.

     I wasn't aware they had 100k simultaneous users, but then I haven't
gone there in a while.

     As mentioned above, commands have more overhead (mostly because they
use callbacks), so any comparisons done with 4.x don't count even more.

     Because they're friendlier and want to chat with the server more?
