You MAY have to start the app (FR) in gdb to figure out what thread is doing
what (sometimes the app will log when threads start and what they’re
doing – but sometimes not). A more seasoned SysAdmin may have an easier
/ better solution, but this method has proven invaluable to me when trying to
troubleshoot multithreaded apps and determine which thread is using most
memory, cpu, etc. and what functions that thread is doing.<o:p></o:p></span></font></p>

<br>
You have changed the server to *slow it down*.<br>
<br>
Why?<br>
<br>
If this issue is so important for you, why are you so insistent on<br>
ignoring *all* help that you get on this list?<br>
<br>
A basic install of FreeRADIUS + MySQL on a normal system will get<br>
100's of auth/s with 10's of 1000's of users in the DB. If you can't<br>
get that, it is because *you* have broken the configuration.<br>
<br>
Don't break the default configuration.<br>
<br>
Follow instructions on this list.<br>
<br>
It's really *not* that difficult to make the server work.<br>
<br>
*Stop* editing things you don't understand.<br>
<br>
All you need to do is to *stop* breaking the server.<br>
