We take as our baseline the raw disk sequential write performance.
We then compare Garage's performances to it, the difference represents what we call our "abstraction cost".
fsync, chunking, compression, pipelining, synchronization
# raw perf VS garage
# garage tmpfs VS garage std
# garage various multipart sizes
# garage 0.7.2.1 VS upstream

# Failure impact
Failures will lead to timeouts, which in turn could
lead to failed requests (this is a bug if failure enters in Garage tolerance)
and to increased latency as some retries might be performed.
How we proceed: we pause (`kill -STOP xxx`) one Garage process.
The idea is we don't want to close the TCP connection that would signal too easily
that a crash occured. Instead, we want to simulate a network error
or an overloaded process, ie. a 'non-collaborating' crash.
