Hi, I'm testing an Authentication script and it's working great. I need to optimize the performance and move some data stored in files into memory. To accomplish this, we planned on placing the routine to read the data into memory in the clone function, so it would load once.

From reading the documentation and the posts I could find. It's my understanding that the CLONE function will only be called once for each new thread created.

In my testing I've noticed that the CLONE function get's called for each Authentication request, so it appears the thread is initialized for each call, even though I see it load up all 32 threads when radiusd initializes. The debug output shows all 32 threads calling the clone function and then it shows the clone function called again when an authentication request comes in. Any ideas on what I could check or change?
