So I did the "timing test" got
 timing test
Attempting to test a timer with 50 ticks per second.
Using the 'timerfd' timing module for this test.


in modules I added
[modules]
autoload=yes
preload => res_timing_dahdi.so
preload => res_timing_pthread.so

Re-ran the timing test got the same thing.
Notice it says specifically timerfd - not timing_dahdi or timing_pthread.
System is CentOS 7.

lsmod | grep dahdi
lsmod | grep dahdi
dahdi_transcode        14291  1 wctc4xxp
dahdi_voicebus         59241  1 wctdm24xxp
dahdi                 228002  9
wctdm24xxp,wcaxx,dahdi_transcode,oct612x,dahdi_voicebus,wcb4xxp,wct4xxp,wcte43x,wcte13xp
crc_ccitt              12707  2 wctdm24xxp,dahdi

Is my timing OK - or not ?

Note /var/log/asterisk/messages says "nothing" about timing even though the
resourse were loaded.

Thoughts ?
