The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

I am not seeing it mentioned anywhere, but for people looking for a good starting point on "low-level" CPU performance debugging, intel's CPU top-down u-architecture method (https://www.intel.com/content/www/us/en/docs/vtune-profiler/...) is a good systematic way to understand where you CPU is speeding most of it's cycle.
They also have two tools which basically implement this analysis and spit a bunch of very useful metric that are actionable and very easy to understand
- Intel Vtune is a fantastic tool to start with. It's currently free to use, support most OSes and very friendly to use for beginner.
- Intel pmu-tools (https://github.com/andikleen/pmu-tools) is basically command line version of Vtune.

if you had to restart at 0 knowledge what would you do?
Install some tool that would help you see the performance of your system, like a graph of the CPU usage, the top processes being used, disk activity/read/write, etc. Every time you run your program, glance at those numbers, eventually you'll develop an intuition. Basically write code and profile. A good exercise would be practicing with data structures, this site has an exhaustive list of them, find some stuff that's interesting then google the implementation, then build it yourself, test it, debug, profile, optimize, and understand the performance constraints. Eventually you'll develop better understanding and can compare between other people's works, optimizing them. If you want to go beyond, read some papers on lock-free algorithms https://github.com/JCTools/JCTools/tree/master/resources then read Brendan Gregg's blog and books.

Toplev is a godsend (thank you Andi Kleen!). If you work with perf you'll love this.

Event Store State of the Art
I've been doing some research and found this: https://github.com/EventStore/EventStore

C#: In Europe, Java is still strong but many trading firms use C# because of the strong Microsoft culture in Europe, as well as because of strongly supported C# libraries like say EventStore, which tends to be used for the matchmaking engines for stock exchanges (especially that exchange matchmaking problem is basically SMR). And skimming over the code, it has Paxos implemented too, making it good for dealing with partial failures (failover), essential for any HFT/trading firm. C#'s also the biggest ecosystem that many of the breakthrough java tech mentioned earlier was first ported to.

3 reasons to adopt Event Sourcing
Where's the catch, then? Well, there's a couple of catches, in fact. First of all, in a distributed setting, appending data to a log isn't that easy. First, you need to make your log distributed. Again, Kafka/Cassandra/EventStore make this possible, however, whenever you start dealing with distributed data, you‘re introducing new operational and implementation complexity.
