One of the issues that keeps coming up as part of this discussion (and
rightly so) is the performance penalty you take when you instantiate a
large number of objects in ColdFusion.
I remember when CF 8 came out, a lot of numbers were thrown out there
regarding the performance improvements (i.e. this operation now runs
43% faster, this tag now works 89% faster, etc.). But so far, I
haven't seen anyone publish such numbers for CF 9, and performance
improvements as a whole was only briefly mentioned (if at all) in
Terry's 2-hour Connect session on Monday.
So do we know if object instantiation performance has improved in CF
9, and if so by how much? Or, being that it's still in beta, is it
too soon to look at that/make a judgment about it?
Thus far I've stuck to queries for anything returning more than one
record, and seeing the code example in his blog entry:
<cfset data=EntityLoad("Books")>
immediately made me think, what about performance with regards to
object instantiation??
Perhaps because it is Hibernate creating Java objects and not CFCs we
will be okay. But the jury is out until some official test results are
in.

I had a quick look at this when I first fired up CF9. I performed a test of
just creating objects with only an init() function, so these numbers are
around the maximum I can get out of CF on my laptop (dual core win xp - just
a moderate machine). Adding functions to components will reduce the
performance.
On CF8 I was able to create 4,000 objects per second.
On CF9 Beta I was able to create around 25,000 objects per second. This
actually started off at a much lower number the first time I executed the
code (around 10,000 per second) but after running the test a few times it
found its way up to the 25,000 mark.

4000 objects per second on CF 8? Wow. That doesn't at all match my
experience of working with complex objects. Perhaps the connections
(aggregation, inheritance) is a limiting factor? Just a guess.

Be interesting to see this benched against Railo 3.1.
Hope they release soon. We are set to launch our .com on the 7th August but
are probably going to have to go CF8 as I assume CF9 won't be out by then.
Hope they offer a cheap upgrade path.

It may be worth reinvestigating it Hal. Obviously the complexity of objects
has an effect but you may find things have improved with later Java
revisions. Once Sun fixed the object instantiation bug CFC performance in
CF8 improved dramatically...

We're launching a big .com next month which I build from the ground up in
CF8, MG2, Coldspring and Transfer. It's by no means super optimised but
after upgrading Java it runs superbly. The beta testing phase has gone well
and the app seems to be performing nicely. Just hope it scales as the user
levels increase..

Performance discussions typically focus on object creation, but I've found
that function execution also carries a significant overhead.
So if you have an object with 20 setters, and all 20 setters are called when
the object is created (say, from an init() function), then this will have a
significant performance impact on the time to initialise the object.
From memory function calls had a similar overhead to trivial object
creation, but I'd need to double check that.

That sounds right to me. I remember hearing that when CF compiles to
Java, each function is actually its own java class. I could be wrong
here, but if not then as CFCs have more functions you get that much
more instantiation going on.

It's important to note Adam Lehman's comments in that thread.
It's also important to notice two new Admin options in CF9: - Cache Template In Request (each .cfc file is only checked once per request) - Component cache (each CFC path found is cached and never looked up again)
These have a huge impact on CF9 performance if you turn them off.
Frankly, I think the performance argument against OOCF is over-used but certainly Railo and now CF9 ought to make people reconsider...
"But even then it can not match POJO performance and thats an
unrealistic target."
Indeed. I agree with Sean that the performance thing is a little
overamped. If you really need to crunch a lot of data, or are really
going to get lot of leverage out of an "everything is an object"
style, CF isn't going to cut it. Not with a 20% improvement, not with
a 200% improvement. But that leaves a huge set of applications where
CF is just fine.
If you like synthetic benchmarks, I tried Kevan's instantiatation test
and got CF8 = ~3500K objects/second, Java6 = ~6M objects per
second. CF doesn't, can't and shouldn't compete on raw performance.

What kind of traffic do you get? Do you rely heavily on Transfer?
