I'm sure this will be not a fresh news for many people, but any way I want to praise Andre Guirard for his really interesting blog site Best practise makes perfect .
I usually find there nice technical postings about Notes/Domino technologies.
Recently I found a post titled: Performance basics for developers where you'll find a link to get a whitepaper about Domino performances issues. Nice work Andre !
Before I forget, Iron Man is a comic book character, a movie and... also an Andre Guirard writing ;-)
