Hello,

Context
In our Biovia system, Chemical registration of a simple compound can take more than 2 minutes. Let's say that a simple compound with a molweight < 400 (less than 25 atoms of Carbon).
And it can take much longer for large molecules like peptides.
Then, I am starting to investigate if we can optimize this process.

Rules
We are using pre-defined rules, and we have put in place some customized rules : 

Most of those customized rules are only propagating attributes between Concept and Lot. 
And I wanted to see if there is not rule which is not too much time consuming.

Then, for my investigation, I have started to register the time when a rule is called, in a log file. I have added these 3 components in the rule 'Calculate Weight and Formula'.

component 1 : create a new property LogDate

component 2 : Add a new line in log file with the time (LogDate)

component 3 : remove the property LogDate

When this rule is running, there is this line in a logfile : 
[Fri Oct 11 15:30:21 2024] .14360.7360: Debug: Start Calculate Weight and Formula

I was surprised to see that for an update of a simple compound, there are 410 new lines in the logfile : 
From 
[Fri Oct 11 15:30:21 2024] .14360.7360: Debug: Start Calculate Weight and Formula
To 
[Fri Oct 11 15:32:09 2024] .7148.4444: Debug: Start Calculate Weight and Formula

Question(s)
I assume that the rule is running 410 times for this update. Am I correct ?
If yes, is it a normal behaviour ?
Would there be something that I could improve here ?

In the documentation, there is a note advising to : 'For performance reasons, ensure that each attribute value is only changed once during population and correction'. How could I verify this point ?

Thanks,
Sébastien.
