Add multi core support

[sdanfa]

Hello,
Is there any plan to add multi core support on udp speeder? It is a very useful app for me but it's lacking multi core support. I hope you can add it.

Thank you!

No plan at the moment.

Multiple-core is not super hard, but I have concerns about implementing it.

Also multiple-core is not the biggest possible improvement. I actually have investigated a avx2 enabled FEC library which can improve the performance by 10x，even if with single-core.   (Combining avx2 and multiple core, it's not hard to achieve a performance improvement of 40x)

But I am worrying about this program being abused.   I have seen a lot that people are sending crazy amounts of redundant packets (e.g. 10 times than original).

So I would like to keep the performance as-is.

In addition:

1. The current performance is enough for my personal use. So I don't have much impetus for my own sake.
2. Currently I am occupied with work, doesn't have much time on this. (I am a visa holder in the US, lost job means lost visa)

If you have large scale commercial use case, you can possibly mail me for collaboration in furture.

Hi, the performance in embedded router is pretty bad right now. Especially the small arm cpu struggle. Will you be able to fix the performance please? It would be helpful for me.

Thanks!

Sorry, no.

If you urgently need, get a more powerful device.

Or trying to distrubute load to multiple UDPspeeder instance.

Thank you so much!
