AES-NI Active But No Significant Increase In Speed Test

Nothing real obvious during a speed test through the VPN:

Install the official client and check some servers if they are able to provide more speed.

@Bob-Dig I am using the same server to test before and after VPN. The difference is massive and enabling AES-NI made no significant difference. Maybe I am overlooking your point.
When I ran the official client the speed did look better but it showed my real IP rather than my VPN IP. I am not sure if the official client is avoiding the VPN somehow.

@Poindexter If you're testing through the third party VPN to the Internet then you're at the mercy of their inbound and outbound connections, and how busy they are. Did they tell you to expect 1 Gbps? I would guess at 4 am it would be faster...

@Poindexter said in AES-NI Active But No Significant Increase In Speed Test:
I have AES-NI showing active but I see no significant speed increase over inactive. Without VPN running I get approx. 820.83 Down and 939.14 Up. With VPN and AES-NI I only get approx. 361.92 Down and 174.86 Up.
You could try out to use AES-GCM-128 instead
of the AES-CBC. -
I wasn't sure if I could change the encryption since the available options were provided by Nord:

Oh I was not really knowing that. I thought you
were creating an account and choose there the
method and algorithm. -
@Dobby_ I tried AES-128-GCM and it is faster!
AES-128-GCM 651.97 Down 234.10 Up
vs.
AES-256-CBC 361.92 Down and 174.86 UpThere is a pretty good difference in usage between the cores but I am still uncertain if AES-NI is working. Thoughts?

The most peoples will be sitting in a thinking trap.
AES-NI is speeding up the entire software and it
will be used by and not your entire task such VPN.But, the AES-GCM is benefitting too from the
AES-NI directly like you can see by your numbers. -
