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.

Probing My SSD's Latency
The Aerospike ACT benchmarking tool characterizes flash devices on their latency under a fixed read/write profile. It won't tell you how fast your device is, it will tell you if a workload runs under a certain latency bound.

IceFireDB: Distributed disk storage database based on Raft and Redis protocol
It depends, yes but ... (not discounting any of the above).
One sees a lot of 3:1 in practice due to the replication factor. If you have 3 copies of the data and the client can read from any node, you get 3x the read performance as having to have a quorum write on two out of three nodes.
To the GP, for a rough swag of what is possible out of given hardware, a combination of FIO and ACT (measures IO latency under a fixed load) is a good start.

Dire SMB speed with on PC to NAS
Assuming two systems use flash storage, network bandwidth is identical and it is configured the same way, there should be an issue within the PC, either system or storage drive. Check the system logs for errors and warning events related to data transfer from/to NAS. Try to benchmark the PCs' disks using fio to confirm they have similar performance. https://github.com/axboe/fio

Ask HN: What are some good resources for learning about low level disk/file IO?
Not specifically addressing your question, but when you get to the point of wanting to start doing some experiments you may find that 'fio' [1] is very handy.

KVM virtual machines on ZFS benchmarks
The dd is not a good benchmarking tool, you should use something like fio and probably tune it to use the ioengine most similar to your use case (eg. a database server will probably use some async IO interface). In your first example (with bs=1G) probably something (the guest OS, the qemu/kvm or the host OS) have split into smaller chunks anyway.

Just write the f*****g parser.
Agree, I used flex/yacc to add an arithmetic expression evaluator to fio a few years back to allow simple math with some units in fio's job files, and for stuff like that, they're fine, but I wouldn't want to use them for a real language, the error handling is kind of a nightmare.
