Yes.Hi all,I am using ncsa_auth to authenticate my users and everything is working fine. Is there any rule of thumb as to the number of users it can handle? Are we talking tens, hundreds, thousands or more.
But more importantly, how long is a piece of string?
Seriously, I would expect an autenticated cache to serve up at least 2/3 the number of outgoing requests/second it could serve without auth (those kinds of numbers have been discussed to death), and probably quite a bit more. Authenticated use does lead to more client requests, but the initial challenge-request is quite light-weight. The only way to know for sure would be to benchmark it yourself.
I seem to recall Kinkie has some big boxes doing heavy loads with NTLM authentication. His numbers seemed to be inline with what I expect from a similarly equipped machine without authentication, so I reckon auth isn't a major performance sink, thought it certainly has some impact.
