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
