* tmbench: Make sendloop act in one second segments Previous behaviour was to make the sendloop send all its messages and then time how long that took. (Possibly waiting if too fast) This has the same operation when too fast, but stops the loop after one second. This is useful if a large tx amount is specified and the ping doesn't get executed. Tmbench no longer crashes on large rates. * Update Readme |

tm-bench
Tendermint blockchain benchmarking tool:
For example, the following:
tm-bench -T 10 -r 1000 localhost:26657
will output:
Stats Avg StdDev Max Total
Txs/sec 818 532 1549 9000
Blocks/sec 0.818 0.386 1 9
Quick Start
Install Tendermint
This currently is setup to work on tendermint's develop branch. Please ensure
you are on that. (If not, update tendermint
and tmlibs
in gopkg.toml to use
the master branch.)
then run:
tendermint init
tendermint node --proxy_app=kvstore
tm-bench localhost:26657
with the last command being in a seperate window.
Usage
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 running via a separate goroutine.
