JSONPath Benchmark

I benchmarked two JSONPaths using several libraries for the Go language. Results can be viewed through Github actions.

The focus of the measurement is the cost per job for a task that involves a significant amount of looping after all the initial preparations are complete.

There were notable performance differences. However, if the number of queries is limited, there will not be a significant variation between any of them.

Additionally, the results may vary depending on the input data. Therefore, this benchmark should be considered for informational purposes only and re-evaluated at regular intervals.

Comparing across all libraries

JSONPath : $.store.book[0].price

The following is the outcome of a JSONPath that was processed by all libraries. The library "oliveagle/JsonPath" performed the fastest, while my own library placed second.

Comparing with a slightly complex syntax

JSONPath : $..book[?(@.price > $.store.bicycle.price)]

Among the limited number of libraries capable of handling complex syntax, my library performed the fastest.
