Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Facebook open-sourcing a more precise time server
It looks like the source for their FBOSS agent that runs on switches will enable PTP in two kinds of supported switches:
https://github.com/facebook/fboss/blob/master/fboss/agent/hw...
They have O(thousands) of switches (source: https://engineering.fb.com/2016/10/18/data-center-engineerin...) so IIRC they get the per-switch cost down by doing a custom design to reduce BOM. I believe the specs and designs are available under the Open Compute project here (search for "Facebook"): https://www.opencompute.org/wiki/Networking/SpecsAndDesigns

latency and optimizations for gaming ?
Other than that, I heard there's some 3rd party network libraries that are generally considered lower latency, one of them I believe either redhat uses for one of their systems, or it is sponsored by them: https://github.com/Xilinx-CNS/onload

Arbitrage and efficient data storage
I mean really you want to be doing some kind of (kernel network bypass with some sort of system programming language like C++ for low latency trading systems like this. Arb trading is usually not worth it unless you have a ton of expertise or some crazy mathematical edge that can offset. Plus you need to be guaranteed to execute the trade you ask for which most average joes don't have.

Facebook open-sourcing a more precise time server
How about the x2 series from Xilinx?
It comes from solarflare who have a long pedigree of low-latency smartnics. They used to supply Cloudflare, and also supply like 50% of fintechs/financial markets.
You can also just use openonload to accelerate your programs. In this case just doing straight linux socket programming, which can be accelerated without dpdk. Or just use the generic linux driver if necessary.

Looking for recommendations on opensource user-space TCP stack implementations that are optimized for latency, not throughput.
https://github.com/Xilinx-CNS/onload any good?

Tcp Offload Woes
It used to be openonload.org which seems to redirect to https://github.com/Xilinx-CNS/onload for the source to onload.
