AFAIK, that is entirely dependent on your hardware. I believe there
are users with many 10s of thousands of users.
CPU capacity is rarely a limit.
You need memory to store the in memory tables and hashes - basically
the more available IPs in pools, the more memory you need. This is
(IIRC) largely independent of how many of those addresses are
And then you disk I/O performance to handle the updates. Firstly to
update the leases file, secondly to handle the logging. This appears
to be the main constraint people hit.
In terms of testing performance, there are some stress testing tools
around - hopefully someone will pop up and suggest which to use.
Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed
author Gladys Hobson. Novels - poetry - short stories - ideal as
Christmas stocking fillers. Some available as e-books.
