We've written a simple benchmark that runs a single RAMCloud client against a
single RAMCloud server, and reads a single objects of a given size repeatedly.
With small object sizes, this allows us to measure the latency of our transport
protocol, and with large objects, we can measure throughput. On top of this
benchmark, we created scripts to plot latency and throughput stats from various
transports for various object sizes. These scripts were used to generate the
graphs on this page and have been helpful in tracking our progress.
Metrics
When working on RAMCloud's recovery system, we created a special-purpose system
for gathering performance counters and timer data from the different servers.
The metrics and their presentation was specific to recovery, but the basic idea
is applicable to this project as well.
