05fdb97df46d0a0675b93e9791bd5d498e5e5117 [doc] Update and extend benchmarking.md (Antoine Riard)
Pull request description:
Trying to make benchmarking docs a bit more friendly.
If you have any more ideas, specially on the Notes section, which component need more benchmarks.
(oh isn't a write-up somewhere to generate flame graphs for core ?)

Benchmarking
|
|
============
|
|
|
|
Dash Core has an internal benchmarking framework, with benchmarks
|
|
for cryptographic algorithms (e.g. SHA1, SHA256, SHA512, RIPEMD160, Poly1305, ChaCha20), rolling bloom filter, coins selection,
|
|
thread queue, wallet balance.
|
|
|
|
Running
|
|
---------------------
|
|
|
|
For benchmarks purposes you only need to compile `dash_bench`. Beware of configuring without `--enable-debug` as this would impact
|
|
benchmarking by unlatching log printers and lock analysis.
|
|
|
|
make -C src bench_dash
|
|
|
|
After compiling Dash Core, the benchmarks can be run with:
|
|
|
|
src/bench/bench_dash
|
|
|
|
The output will look similar to:
|
|
```
|
|
| ns/byte | byte/s | error % | benchmark
|
|
|--------------------:|--------------------:|--------:|:----------------------------------------------
|
|
| 64.13 | 15,592,356.01 | 0.1% | `Base58CheckEncode`
|
|
| 24.56 | 40,722,672.68 | 0.2% | `Base58Decode`
|
|
...
|
|
```
|
|
|
|
Help
|
|
---------------------
|
|
|
|
src/bench/bench_dash --help
|
|
|
|
To print options like scaling factor or per-benchmark filter.
|
|
|
|
Notes
|
|
---------------------
|
|
More benchmarks are needed for, in no particular order:
|
|
- Script Validation
|
|
- Coins database
|
|
- Memory pool
|
|
- Cuckoo Cache
|
|
- P2P throughput
|
|
|
|
