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.

Rsync extremely slow on two ZFS local pools
Native rsync is terrible for lots of small file as it copies each file one by one sequentially. If you have lots of cores to work with, use the fpsync utility that comes with the fpart command to run parallel rsync's. You can easily saturate a 10Gb link with multiple rsync processes in parallel

Am I crazy to expect 100gbps across the pacific ocean?
You should probably use something like fpsync and multiple rsync jobs to get the most bandwidth.

Advice on 100gbps WAN?
My favorite free solution is fpsync/fpart from https://github.com/martymac/fpart -- basically that is a highly optimized filesystem crawler and indexer that can spit out balanced lists of files to transfer to a waiting army of parallel rsync workers. Tools are provided to manage the rsync fleet. Combining fpsync/fpart with an army of parallel rsync workers is a great design pattern especially for HPC as you can farm the rsync workers out to compute nodes

zfs replication vs multithreaded rsync
I've migrated data from our Isilon to zfs hostA using the fpsync tool that comes with the fpart utility. I get reasonably good throughput from this. 15TB in 5 and 1/2 hours
