Imagine having control over the behavior of your code! That's the advantage of writing it. And I thought we were talking about replacing open source packages, not doing open-heart surgery on a faulty package?
Why would you think that? I explicitly said "Apart from the OS (which isn't where the problem lies), there's no open source in it."
It's a 3rd party commercial platform for developing your own applications on. To rewrite individual bits that aren't working efficiently would be a nightmare.
As for imagining having full control over the behaviour of my code - I had that quarter of a century ago or more when I started coding, and spent weeks or months building windowing systems and low-level networking code in assembler that I could achieve in 30 seconds with any off the shelf language these days.
Yes, my code was extremely efficient (it had to be, trying to do graphical comms software on 8086 machines didn't give you much of an option to do otherwise), but the use of my time wasn't.
The third party product that we're using is the result of many years of a large team of dedicated developers. Rewriting that from scratch in order to make sure we've got full knowledge of what's going on is an utter ludicrous idea.
