AirVPN on router, slow speeds

[macfanboy 0]

Hi

 

I have installed dd-wrt on Netgear R6400, i followed the official guide for configuring AirVPN on it, and

the problem is that im getting maximum speeds of 10-17mbps instead of around 70mbps.

 

Are my settings fine ? what could i try ?

 

 

Thanks

That's just the limitation of the CPU.  It takes a lot of power to encrypt/decrypt openvpn quickly.  Or AES-NI.

I had performance improvements by adding the following to the "Additional config":

 

 

    # Lesser values, for both, could be 393216
    sndbuf 524288
    rcvbuf 524288

 

 

Try this and see if it helps. But as mentioned, you're probably limited by your router's CPU not just configuration.
