Anecdote of when NSS is a bottleneck: trying to start FF in a fresh VM. There is not enough entropy, NSS insists on /dev/random instead of /dev/urandom, and so FF start blocks until NSS has enough random data.

Intel Dramatically Speeds Up NSS With AVX2

Originally posted by bastiaan View PostAlthough I agree it is a good thing that Intel is participating in this project, I'm also a little skeptical. If you have a modern Haswell CPU, is NSS processing really going to be a noticable bottleneck for your average browsing session? I don't think so. Perhaps we are indeed looking at a technology demo with little impact.

now if the algorithm can operate with FP then it can use AVX just fine.
abut FMA4/3 im not entirely sure either can handle integer vectors.
so as a thumb rule AVX1 Floating Point only and AVX2 Integer only

slackware never had
would that help ?
this is broadly used in custom kernels & ROMs on android smartphones over at xda-forums
