Hello,

50K might be a lot. However, none of them need a preprocessor. My concern
is why preprocessing verification is still taking place?


It is verifying an empty list of preprocessors.  Happens very quickly.  :)
That line is always output.

The next step has to do with fast pattern setup and that is what is taking
some time.

You are loading 50 thousand rules, and you are wondering why Snort is
taking a long time to start up?

Hi,

Yes, all lines are commented out. by the way, I am using beta version
2.9.1. Snort initialization shows that no preprocessor rules are used.

Initializing rule chains...
50001 Snort rules read
  50001 detection rules
  0 decoder rules
  0 preprocessor rules
50001 Option Chains linked into 1 Chain Headers
0 Dynamic rules

Hello,

I am not using any preprocessor.

really? no preprocessors at all?? each and every one of them are
commented out
in your snort.conf?

However, still snort does the "Verifying Preprocessor Configurations"
step at the loading stage. Is there any way to turn this off as it takes
long time as the rule file grows.

"
Rule application order:
activation->dynamic->pass->drop->sdrop->reject->alert->log
Verifying Preprocessor Configurations!
"

Thanks
