Prompted by a conversation with some colleagues where-in we collectively speculated about the implementation details of a generic class and what impact – if any – this might have on performance vs a “traditional” polymorphic equivalent, I threw together a quick performance test case in my Smoketest framework, and as a result discovered a couple of significant changes in Delphi 2009 that created some unexpected problems.

Since I’m preparing a series of posts about (and eventual publication of) Smoketest, my own testing framework, I thought I’d test the water with this weeks poll and see what – if anything – people are already using as far as unit testing goes.
Also I thought I’d briefly mention that I am at Microsoft Tech Ed ‘08 (NZ) this week, and it was good to see that the NZ CodeGear reseller, Developer’s Inc were handling a steady stream of traffic at their stand where Delphi 2009 was on display (in the form of data sheets 
).
I asked when Delphi 2009 was expected to ship and was told that it had been released to manufacturing and was on target to start shipping on 20th September – I forgot to ask whether that was an NZ date or worldwide.
Not quite from the horses mouth, but pretty darn close.
A colleague of mine directed me to a further minor refinement of the ‘final’ Exchange() code I posted the other day. The change is minor but yields a worthwhile performance improvement, but my main reason for bothering to post (yet!) another update is an excuse to introduce the testing framework I developed that allowed me to quickly assess any benefit.
