NetBenchKit

NetBenchKit is a transport-layer diagnostics toolkit designed for systems where TCP and UDP behavior directly impacts application performance.
The library provides controlled benchmarking profiles, low-level socket probes, and reproducible metrics suitable for modern web infrastructure.

Overview

NetBenchKit focuses on transport predictability under load.
It evaluates handshake overhead, packet delivery precision, connection churn handling, and throughput consistency across a wide range of network conditions.

The toolkit is suitable for high-traffic services, API gateways, distributed pipelines, and testing environments that require deterministic network behavior analysis.

Core Features

Transport Analysis

• TCP handshake timing
• UDP variance and packet drop behavior
• Throughput and flow stability
• Stall and retransmission indicators
• Payload-level latency distributions

Profiling Models

NetBenchKit provides configurable profiling modes for:

• Long-running persistent connections
• High-frequency short-lived connections
• Burst-pattern traffic
• Mixed workloads reflecting typical web service pressure

System Context

Optional OS-level insights include:

• NIC utilization
• Kernel buffer usage
• Socket queue saturation
• Latency fluctuation under resource contention

Interoperability

The toolkit integrates cleanly with:

• Web servers
• API gateways
• Reverse and edge proxies
• Load-balancing layers
• Microservice performance pipelines

Example

from netbenchkit import TCPProfile, Benchmark

profile = TCPProfile(
    target="192.168.0.10:8080",
    connections=150,
    duration=10,
)

report = Benchmark(profile).run()
print(report.summary())
