Why using my own Sys.vm slows down programmes a lot?

[Azuuu]

Hi! I've implemented the jack OS and understand there are some drawbacks of it e.g. graphic and memory operation being inefficient. But I don't understand why using my own Sys.vm would slow everything down a lot. Could anyone please give me some insights about it?

Cheers!

Are you saying that it is slowing down when the only OS file that you are using of your own is Sys.vm?

[Azuuu]

Yes. That's exactly what I mean.

[WBahn]

I don't know why it would slow it down a lot.

You might send me your Sys.jack file and I can take a quick look. No promises.

Hi. I've emailed you. Please check out :)

I haven't received anything -- you might resend.

Possibly your implementation of Sys.wait() ?

If your Sys.wait() uses your Math.vm, it might interact differently to when you unit-tested your Sys.wait() with the built-in OS Math functions, so you may need to retune it.
