FreeRadius is 3 time quicker when running in full debug mode ( -X option)

Alan and other list member,

It seems that the difference of performance is due to multi thread feature.
When running freeradius with -s option ( single mode ) I have similar
performance than in debug mode.
That make sense as -X is equivalent to -sfxx -l stdout.

So new questions are:
How can I take benefits of  freeradius multi thread option and keeping
good response time ?

According to the man page "Some systems have issues with threading" is
there any system configuration that can help ?

And finally if I decide to stick to single mode how can I modify the
/et/init.d/freeradius to use the -s option ?

Many thanks in advance for your support.
