[Jool-list] Jool performance help

[ali at acreto.io]

Hi,

 

Good morning.

 

I've installed Jool kernel modules and userspace application on Ubuntu.
jool_siit is running in a network namespace and I'm using veth pairs for
network I/O. Please find attached details of my test environment.

 

However, while running the TCP throughput test, I was able to achieve only
6Mbps of throughput. I've tested it by doing both GRO on and off on all the
relevant interfaces with no performance improvements.

 

We are evaluating Jool for carrier grade NAT64 in our network
infrastructure. 

 

I was wondering if you can help me to improve performance results. Is there
any tweaks or workarounds to overcome the performance limitation by Jool.

 

Below are the details of my environment. 

 

Any help would be greatly appreciated.

 

Thanks

Muhammad Ali
