Cowrie Benchmarks

Performance benchmarks for Cowrie codec implementations.

Running Benchmarks

Go

cd go
go test -bench=. -benchmem ../benchmarks/

Python

cd python
python ../benchmarks/bench_python.py

Rust

cd rust
cargo bench

Benchmark Categories

1. Encode/Decode Speed - Operations per second for various payload sizes
2. Payload Size - Compressed size vs JSON
3. Memory Usage - Allocations during encode/decode
4. Graph Types - Performance of new v2.1 graph types

Expected Results

Throughput (approximate)

Implementation	Gen1 Encode	Gen1 Decode	Gen2 Encode	Gen2 Decode
Go	~500 MB/s	~600 MB/s	~300 MB/s	~400 MB/s
Rust	~450 MB/s	~550 MB/s	~250 MB/s	~350 MB/s
Python	~15 MB/s	~20 MB/s	~8 MB/s	~12 MB/s

Payload Size Savings

Payload Type	JSON	Gen1	Gen2
Small object	100%	~90%	~85%
Large array (repeated keys)	100%	~85%	~60%
Float array	100%	~50%	~50%

Gen2 shows best savings with repeated object keys due to dictionary coding.
