nbson_bench is an OTP library to benchmark nbson.
The nbson_BENCH script under priv measures the decoding and encoding times for a series of BSONs containing from 1 to 1M documents using nbson. This escript also executes such deserializations using bson-erlang, a well-known BSON encoder/decoder, for comparison purposes. To execute the benchmark yourself, please run rebar3 compile before executing the script.
Executing the measurement using the .bson files under priv/data produced the table below. Each row corresponds to measuring the decoding time of the BSONs in a given file. The first column specifies the number of documents inside each BSON file, the second column specifies the byte sizes for each of those BSONs and the third and fourth columns show the measured times in µs for nbson and bson-erlang respectively.
You can also execute these benchmarks by running a shell and using the nbson_bench API.
