Tendermint blockchain benchmarking tool:
For example, the following:
tm-bench -T 10 -r 1000 localhost:26657
Stats Avg StdDev Max Total Txs/sec 818 532 1549 9000 Blocks/sec 0.818 0.386 1 9
This currently is setup to work on tendermint's develop branch. Please ensure
you are on that. (If not, update
tmlibs in gopkg.toml to use
the master branch.)
tendermint init tendermint node --proxy_app=kvstore
with the last command being in a seperate window.
tm-bench [-c 1] [-T 10] [-r 1000] [-s 250] [endpoints] Examples: tm-bench localhost:26657 Flags: -T int Exit after the specified amount of time in seconds (default 10) -c int Connections to keep open per endpoint (default 1) -r int Txs per second to send in a connection (default 1000) -s int Size per tx in bytes -v Verbose output
How stats are collected
These stats are derived by having each connection send transactions at the specified rate (or as close as it can get) for the specified time. After the specified time, it iterates over all of the blocks that were created in that time. The average and stddev per second are computed based off of that, by grouping the data by second.
To send transactions at the specified rate in each connection, we loop through the number of transactions. If its too slow, the loop stops at one second. If its too fast, we wait until the one second mark ends. The transactions per second stat is computed based off of what ends up in the block.
Each of the connections is handled via two separate goroutines.
