Intel QuickAssist at 40GbE Speeds: IPsec VPN Testing

[Cliff Robinson]

We take Intel QuickAssist cards into a 40GbE IPsec VPN network test to see if we can get the promised throughput and lower CPU utilization.

can i get more context on this image:

On the far left I think I see ~ 10 cores doing ~40Gbps with "QAT" presumably enabled.
In the middle I think I see ~10 cores doing ~35Gbps without QAT
On the far right I think I see ~37.5Gbps with ~6 cores with QAT.

Basically far left and far right bars as labeled are confusing for the noob in me.

I was not overly happy with that graph. I believe your 6 cores with QAT is actually 2 cores (blue bar = left axis with both labeled "Cores" and black bar = right axis with both labeled (Gbps).

I may see if I can hack at Cliff's chart later and get something clearer.

Honestly, it's starting to read like you're getting a percentage on QAT. For comparison's sake, could you show performance & CPU utilization for AES-128 GCM rather than CBC+SHA?
