Hi Brian I am using nginx openssl async: https://01.org/sites/default/files/page/nginx-1.10.0-async.l.0.3.0-001_0.tgz with my async RSA accelerator. Where can I find the updated version of this work?
Can you share your plans to upstream this work?

My two cents here(Intel Quick Assist specific, based on conversations during Nginx.Conf): 1) Even without hardware offload async handshake helps in cases where you have high TLS connection rates, because right now handshake is basically a 2ms+ blocking operation(specific timing depend on AVX/AVX2 support[0]) inside the event loop. Therefore after some TLS connection rate nginx performance falls off the cliff. 2) Hardware offload numbers look very impressive[1](TL;DR: 5x improvement for RSA 2048, for ECDSA, imho, it is neither impressive, nor needed). Also they prove asymmetric part of the accelerator to be future proof, so that it is possible to add new handshake types(e.g. Ed25519). Disclaimer: we did not test that hardware yet. As for patches, you can check 01.org for: a) nginx openssl async: https://01.org/sites/default/files/page/nginx-1.10.0-async.l.0.3.0-001_0.tgz b) zlib[2]: https://01.org/sites/default/files/page/zlib_shim_0.4.9-001.tgz (Full list of docs: https://01.org/packet-processing/intel%C2%AE-quickassist-technology-drivers-and-patches ) Question for Brian/Maxim: are you planning on integrating it into mainline nginx? 1000+ line diffs are usually rather hard to integrate. [0] FWIW, speaking about OpenSSL performance: using OpenSSL 1.0.2 + Intel Xeon v2 processors with AVX2 gives 2x performance boost(over OpenSSL 1.0.1 and v1).
