This is quite high, zaptel/asterisk here running on
FreeBSD-6.1 shows
around 0-1%.

You can get the latest zaptel for FreeBSD via subversion and
it compiles
with no problem on 6.1-RELEASE.

If you need any help please let me know.

I just checked and I'm on 5.4 p8 and experiencing the same
thing.   
This is on a 2.0Ghz Celeron with 640MB of RAM.

Does anyone have better experience with alternate analog
cards?  I get
echo problems and other wierdness (like a race condition
where someone
calling in gets the same line as someone trying to call out,
so the
calling person hears tones and then someone saying
"hello?").  I have the
feeling the race condition is more a driver issue then
anything else.  The
echo stuff I blame on the card.

Performance on the Via processor is a total dog but it is
not so bad  
that usage should be 20-26% I use the
Nehemiah C3 1200mhz and have not had this problem even with
four  
calls going through the TDM400 CPU
utilization is not spectacularly high.  I'm not exactly
sure how high  
but I can say that performance investigation
has not been something that came up.

you are running revision 37 of the zaptel-bsd drivers, right
? my only 
suggestion is to try it on freebsd 6.x as that's been the
development 
platform for the drivers. in addition, stuff under the
freebsd hood (kernel 
scheduling for starters) has changed tremendously in the
move from 5.x to 
6.x, and you're bound to see performance jumps.

Yes, 37.   It's actually working well,  except for the
interrupt issue.  
  No problems
with echo or anything.

I'll load 6.x up and see what happens.

Thanks.
