Re: [DFW CFUG] Reactor Performance Issues?

some more stats, on creating that user object (1 record), setting the fields (like firstName, email, etc), and saving it back to the database:
 
around 3000ms
the sql database is on same local machine, my dev box.  (2GB ram, amd 3500)
 
1121 method calls
 
there is the point where you can over-normalize and abstract things for any use, but comes at a heavy performance penalty.  conversely, procedural code tends to run pretty quick, but at the penalty of extensibility and manageability.  normally, what we're all looking for is a happy medium between the two - this is more on the over-normalized (to a bad degree) side of things.

I set it up to try it out this last weekend, just to see what it was like.  WAY too slow IMHO.
 
To create a simple user object (5 fields, only 10 rows in table so far), set the fields to a value and save to the database (about 10 lines of code) - took over 3000 milliseconds!!   Wowsers!  And getting data - slooooow.
 
Eh, I'll pass for now.  =)
 
I use a DAO / Bean type of methodology for my data objects and I have some core objects I extend which makes it go pretty quick (like built in event methods onBeforeSave(), save(), OnBeforeDelete(), loadFromQuery(), etc).  As an additional bonus, if you install the CF-FB extensions for Flex builder, you can have it generate your bean, DAO and a gateway object for each table in the database with about 3 clicks.  Also, you might check out CF PowerTools, it will generate this same starting code for you as well and has some additional features.
 
Databases don't change that often, and I find that modifying my source after the fact is fairly quick and painless - especially if you've made sufficient unit tests for your objects.  Its really the initial creation of your components that I think most people use this type of thing for.  So, why take a continuing (fairly serious) performance hit, just to save yourself a little time (that can be quickened with other generators out there - FlexBuiler/CFPT - etc)
 
TMMV

I remember someone talking about problems with Reactor's performance.  We are thinking about moving from our code generator to Reactor because of the more powerful features it offers.  What do ya'll have to say about Reactor and performance?
