# Utils/MBen
| |||
| |||
Benchmarking helper for timing multiple code blocks/operations and persisting the results to a local SQLite database for later comparison.
| |||
| |||
## Main features
| |||
- Accumulate timing samples per operation/dataset in memory (`CMultiBenchmark::Add`).
| |||
- Flush all accumulated samples to a local SQLite database, creating the table if needed (`CMultiBenchmark::Finish`).
| |||
- Parse a previously generated `.log` file (with a `[MultiBen&` tagging convention) and flush its results to the database as well (`CMultiBenchmark::ParseLogFileTodayFlushDb`).
| |||
| |||
## Basic usage
| |||
```mql5
| |||
CMultiBenchmark::Add("parse_json", "dataset_1000", 1, elapsed_microseconds);
| |||
// ... repeat Add() for each iteration/operation ...
| |||
CMultiBenchmark::Finish("benchmarks.sqlite", TimeToString(TimeLocal(), TIME_DATE), "MyLib");
| |||
```
