I thought the essence of the argument against this is the fact that such testing doesn't happen one at a time, but instead in unison with one another.  So if 20 queries are sent out and the first 10 that come back to put the score high enough to fail, there isn't really that much overhead in waiting for the remaining 10 to come back considering that they have already been queried.

I'm not sure exactly how the application handles the technical tests, but it would seem that many of them are done in unison as opposed to independent of one another just like the DNS-based tests.  HELOBOGUS, SPAMHEADERS and BADHEADERS for instance all look at the same pieces of information, so it's probably not something that can be separated into individually triggered tests.  I would think that by the time you caught a high enough score, the majority of the processing would already be finished and you would only be waiting on the remaining DNS queries to come back.

Another issue is that score handling is only marked in the $default$.junkmail files, and you can have different settings for each domain and user depending on your version, yet there is only one global.config file that gets used for every user on a system.  So knowing what score to stop on becomes overhead since the system doesn't need to keep track of handling information during testing as things stand, and beyond that a logic mess for a programmer.

I guess that while what you suggest would be nice in some circumstances, it might not be practical programmatically???

I'm also going to guess that some of the newer tests that involve opening, parsing and execution of files like SPAMDOMAINS and SPAMCHECK would have a noticeable impact on the processor cycles needed, and that might be why you are seeing the increase that you are.  Some DNS-based tests might also be slow in responding, and might also rarely return a match, in which case it would make sense to remove them if you are worried about processing time.

I'm no expert on the details, but that's what makes sense from what I think I know :)

I've Added
2 x Subjectspaces
Spamdomains
4 x Comments
Spamcheck
And a host of DNS tests. 
 
    That's my CPU, Bandwidth, and other resources.   And as more and more people move to spam prevention it seems the DNS Blacklists will get more use. 
 
   I guess my point is why continue to test and use resources once you reach a certain point where you're 3X, 4X or 5X your hold weight? 
 
    Any thoughts?

John,
 
    As I mentioned, the order that you ran the tests would affect the outcome.   Tests that generate a negative weight would need to be run first, such as IPNOTINMX, BONDEDSENDER, and other whitelist type of tests.  Also the reason I suggested stopping testing at weigh 3x my HOLD weight.  This gives some margin where test would continue to run.

You do not want Declude to stop at a certain point. What if it stops, right before the next test which is a whitefilter type test?

 

With the weighting system, it is important to run all tests to get the final weight.

Subject: [Declude.JunkMail] Setting MAX Testing Weight

 

    My Declude config has grown since install.  I am curious if it is possible determine a Weight at which Declude ceases running tests on an email. 

 

    Say I have 40 tests and after Declude runs the first 10 of them it accumulates a score of 300.  I HOLD at 100.  Further testing beyond 300 uses additional resources to produce the same outcome with no additional benefits.  Resources including  processing, bandwidth, and un-needed additional queries to blacklist servers that are working hard to maintain their services.

 

    In this scenario the order that Declude ran your tests would be a factor.  You could place your tests in a specific order in the Declude config  so that primacy tests like Spamcop were first, and additional tests would only be run if needed.  Or you could run tests like Spamcheck, Badheaders, Helobogus first and be able to HOLD messages with a minimum or no external DNS queries.
