Low VPN Throughput

hi..

yes enabled in the firewall

Coming back then to this remark...
How does CPU usage look like now ?

my cpu now

Next thing to try might be MTU tuning and/or mss clamping.
But it looks like you're getting close to the max of what that device can do.

Don't forget :
those test results you refer to, the one with +200Mbps, are for 1400 byte packets.
In real live you will probably be a lot closer to 512 byte packets and then 80Mbps might sound just about right.

Should i change my ether5 MTU to 1400 for better throughput?

Hi I testing out hex refresh for CPE IPsec endpoints. With beta and no bridge I can do 200 Mbit IPsec aes 256

But if I use a bridge on interfaces to lan it drops to 160 Mbit

I think there is a bug in the firmware because if I use latest stable speed drops to 80 Mbit around. I do speed test using libre speed test inside the VPN.

Better performance I get using ac2 and ac3 but also only on beta.

We are talking about RB760 here.

Completely different then Hex Refresh ( and yes, that problem has been solved in one of the latest beta versions).
Ac2/ac3 have better cpu then Hex refresh.

It might be best to start your own thread if you think this problem requires more assistance ?
