The theoretical max TPS test is a configuration of the MaxTPSClassic mission
that searches for a maximum transaction-per-second rate that stellar-core can
support under ideal circumstances. It uses a network of 7 stellar-core nodes, of
which 3 are validators. We provide this topology in
/topologies/theoretical-max-tps.json.
To run the test, first set up an EKS cluster. Then, run a
MaxTPSClassic mission with the following template:
dotnet run --project src/App/App.fsproj --configuration Release -- mission MaxTPSClassic --image=<core-image> --netdelay-image=stellar/sdf-netdelay:latest --pubnet-data=<path-to-repo>/topologies/theoretical-max-tps.json --num-runs=<runs> --tx-rate=<min-tx-rate> --max-tx-rate=<max-tx-rate> --namespace default --ingress-internal-domain=<domain> --ingress-class=nginxFor more information about how to set the parameters in the above command, see Measuring Transaction Throughput.
At the end of the test you should see a line that looks like:
Final tx rate averaged to <rate> over <runs> runs for image <core-image>
Finally, don't forget to shut down your EKS cluster.
This table contains the theoretical max TPS stellar-core achieved, ordered by stellar-core release.
