Dear All,

I have a VPN between a Cisco Asa 5510 and a Asa 5515X the link bandwidth is 80Mbps.

Testing the bit/rate I see that when the connection starts from the 5510 toward the 5515X, I got bit rate up to 78 Mbps.

When I try starting the traffic from the 5515X toward the 5510 I got a bit rate up to 40 Mbps.

Someone can explain me why?

Best regards,

Igor.

Hi

Can you tell which tool you are using to test the same.

Regards

Jagmeet

Hi,

Iperf Version 3

If possible can you please share the screenshot of the output from the iperf from both the side ?

From the 5515X toward the 5510
