Hello Adam,

Thank you for getting in touch.

What did you change in your scripts?

Generally I would say yes. Does it come with any downsides?

I am not aware that anyone ran into resource issues here, because PPP connections are usually rather slow (up to 100 MBit/s). But we would probably gain some throughput by better utilisation of the load-balancing on the IPS, etc.

What are you doing here? Are you assigning a processor to a queue using that script?
