We have two of this machines here. It has exactly the same config from the
screw who hold the server in the rack up to each dot in the junkmail config
file (except the license codes ;-)

The first server seems processing messages faster then the second.
On the second server the more I play with values the lower CPU-usage and
processing goes. After each reboot of decludeproc it's going down a little
bit. Neither a reboot solved the problem. When I block incomming
SMTP-traffic on the second server it will process around 50 messages per
minute by showing up an average CPU usage way below of 50% (currently 20%)


> 1. What is your THREADS in the Declude.cfg ?

Everything from 5 up to 500


> 2. Are you running many large filters ?

I've tried enabling und disabling many filters without any noticeable
change. But large filters should create a large cpu-usage. 


> 3. How many virus scanners are you running ?

Usualy two but I've also disabled the second for testing without any result


> 4. Is hyperthreading turned ON or OFF ?

Yes task manager is showing up 4 cpu's


> 5. Are you using any other Directives in your declude.cfg ?

Beside THREADS I've currently in use

WAITFORMAIL             5000
WINSOCKCLEANUP   ON

I've tried changing WAITFORMAIL up to 15000 ms as suggested by another v3
Admin and I've also tried  adding

WAITFORTHREADS          1500
WAITBETWEENTHREADS   1

With values from 150 .. 1500 and 1 .. 1000 without any noticeable change in
the task manager cpu usage.

The number of queue files in the proc folder is going up and down (something
between 1000 and 12000 files)
The server is working and delivery messages but only with 50% of his power
and speed.

Netstat is showing around 100 ETSABLISHED connections and around 50 in
TIME_WAIT
The process list in the task manager is showing up around 50 entries
