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

[Vincent Laborie]

Dear Freeradius User list,

I am surprised by the fact that freeRadius (Version 2.0.4) is 3 time quicker
when running in full debug mode ( -X option).

When running freeradius I full debug mode
/usr/sbin/freeradius –X
 I have good response time from remote client were between 200 and 210 ms.

But  when I launched freeradius without debugging (with exact same
configuration):
/usr/sbin/freeradius
Or /etc/init.d/freeradius start
the response time increase to 600ms

It is usually the opposite where turning off debugging should increase
response speed .
Does any body have an explanation?
Or any clue to improve performance on non debug Mode ?

Thanks in advance for your support.
Vincent

Alan,

Many thanks for your answer,
I had a look to syslog and it seems that my server is already using rsyslog:
ps -elf | grep syslog
5 S root  1963 1  0  80   0 -  7041 -  Mar20 ?
00:01:56 /usr/sbin/rsyslogd -c3

I also try to print directly on stdout :
destination = stdout
Or in files
And this doesn't realy change anything.

I also tried to reduce logging as much as possible for example by commenting :
#auth_log
but it doesn't realy help too.

Looking forward to any clue that will help me to reduce this response time,
Thanks,
Vincent

  You are logging to syslog.

  Use a syslog server that doesn't kill performance, like rsyslog.
