Here is my test. pfsense spec is in the signature :)

So the real number is 691702, which is actually a bit low for a skylake @2.7GHz.

Revisiting this thread, many have noted that results are all over the map.  Here are some more results from my Zotac ZBOX ID92.  This is the exact same command being run.  I noticed that the openssl command is single threaded (edit: somebody else mentioned that) as it only loads one of the available four CPUs.  The highest 8192 bytes result is 182,250,987k.  The lowest is 18,290,730k.  I don't know what to make of these results.

The 'numbers' are in 1000s of bytes per second processed.

Well, if you'd read what I wrote above you'd understand completely: the posted results are useless noise because people are using cryptodev in their testing without the -elapsed flag and aren't actually measuring anything to do with crypto performance. It's immediately obvious for anyone familiar with the openssl implementation just by looking. Your system isn't capable of transferring 182GByte/s, full stop. So any result showing that it is can be immediately discounted. Run again with the -elapsed flag and you'll see consistent number which actually reflect what you're trying to see. Or turn off aesni.ko, it's probably only slowing you down anyway.

I tried it with the 'multi' option to load up all four CPUs (2 physical, 2 SMT).  Here are the results of the first try.  Can anyone decypher what this means?

[2.3.2-RELEASE][root@pfSense.home]/root: openssl speed -multi 4 -evp aes-256-cbc

-multi forces -elapsed, so you're actually seeing a real number which is shockingly low compared to the artificial numbers that people have been drooling over. run "kldunload aesni.ko" to kill the cryptodev implementation and rerun, you should see an order of magnitude improvement for smaller block sizes and a smaller but still substantial improvement in large blocks.

That makes sense.  I tried the multi 4 and multi 2 options and it pretty much scaled perfectly with my original one core - elapsed score.

This makes more sense.

@Chucko:

Adding -elapsed to the above command only changed results by ~2%.

Yeah, without aes-ni cryptodev isn't in play, and while -elapsed gives a less accurate result when using openssl's internal crypto routines the two numbers should be pretty close.

Interestingly enough I ran the same test on a VM running on a i7 Q70 that has no aes acceleration at all and the numbers were about half what the AES accelerated chip did.
The first test is running on a 8 core AMD 8150 and the second (values are all approx half) ran on a very old wimpy i7 quad core with no AES-NI.

I would expect the AMD to run 2 or 3 times faster even if it had no AES-NI.  Basically I don't feel these test mean very much and that the only way to gauge performance is an actual throughput test using vpn traffic.

The number of cores is irrelevant, it's a single threaded test. (It's also worth pointing out that your bulldozer era chip isn't really 8 cores, it's 4 cores that have a multi-thread implementation similar to intel's hyperthreading, and the early releases weren't tuned very well.) I don't have any numbers for the FX-8150, but it's is an old CPU, so your results aren't necessarily unreasonable. I have tested bulldozer-based opterons and I'd have expected your results to be a bit higher based on clockspeed, but I don't have the data points to know how the results should scale on the desktop chips of that line. I would double check that you have the cryptodev checkbox turned off because that will slow things down, but that might be as good as it gets.

It's important to remember that AES-NI implementations have evolved a lot over the years, so there's a whole lot more to performance than its simple presence. You are correct that the openssl speed results alone aren't going to predict OpenVPN performance, but they are a datapoint that can help predict performance relative to other known systems, and can help establish a ceiling on performance. (E.g., a system that can only perform AES-256-CBC at 30MByte/s is never going to get more than 240Mbit/s of VPN, and much less in practice.)

The AES test is single threaded?  Is openssl also single threaded during normal use?

Yes, as is OpenVPN (what you probably mean to be asking about).
