This very much depends on the time it takes to validate a user. If your
script is fast then only a few of them is needed, if it takes a lot of
time then more are used. It also depends on the burstiness of your
users. If all users start browsing at approximately the same time then
the requirements will be higher than if they start at times more evenly
spread out during the day.
Another note: Having mutiple authenticator processes also requires that
the backend database can handle it, or there is not much of an point in
having more than at most 2.
A good approach is probably to make some estimate based on the time the
authentication takes and how many users you think will be starting
browsing at the same time, and then keep an eye on the usage stats from
cachemgr. If you see that all authenticator processes are used a lot
then you need to add a few more, if you see that there are a lot of them
not being used at all then you might reduce the number a bit (or keep
them as a buffer for future bursts).
