In these three emails, 80% were giving facts (basically, the benchmarking I've done) and the 20% of the rest were saying that I believe that you are optimizing the wrong parts and explaining WHY I believe so. Having re-read these emails (3 times), I really don't see any bashing (but I've been told that I have a high threshold to consider something bashing).</div>
<div><br></div><div>The most offensive statement is probably</div><div> I<span style="font-family:arial,sans-serif;font-size:13px">n other words: you are attempting to optimize something without having done any profiling. This is a cardinal sin.</span></div>
<div>Which is true and true:</div><div> - you would have shown some detailed profiling of pocolog runs if it was otherwise</div><div> - optimizing without profiling is like debugging by looking at the code: trying to do science without doing any experiment ever. </div>

That's what bothers me here (and why I think you're looking at the wrong angle). It would leave 75% left to optimize after your changes. Or maybe my benchmarking is wrong. You want to handwave it away ? Your choice to make ! But simply say so instead of calling me names.</div>
<div><br></div><div>You've measured that typelib demarshalling is not the issue ? Great, you proved me wrong there, I can have a look elsewhere (Mea culpa: I did affirm in a previous email that it was the problem without having profiled it yet. Having done some real profiling today, I could have told you that it was indeed not the main issue). Now, it does *not* remove the fact that I replay (with a clean pure-pocolog script) a lot faster that yours do. The question I am asking myself is why. It seems that I should be ashamed that I do.</div>
<div><br></div><div>Anyways, this closes the issue for me. F.. do whatever you want.</div><div>Sylvain</div></div></div></div>
