# Requirements

```

yum -y install nghttp2 gnuplot jq

```

psrecord and matplotlib for logging and chart plotting for local Nginx resource usage

```

pip install psrecord

pip install matplotlib

```

or

```

pip3 install psrecord

pip3 install matplotlib

```

# Usage

Includes a [Batch Mode](#batch-mode) with charting support. Example charting for:

* [VPS benchmarks](#batch-mode-vps) 

* [Dedicated server benchmarks](#batch-mode-dedicated-server).

* [Comparison Charts](#comparison-charts)

* [psrecord](#psrecord)

```

./h2load-bench.sh 

Usage: ./h2load-bench.sh [-t threads] [-c connections] [-n requests] [-D duration] [-w warm-up] [-u uri1,uri2,...] [-b batch] [-C compress] [-f format]

Options:

  -t, --threads       Number of threads

  -c, --connections   Number of connections

  -n, --requests      Number of requests

  -D, --duration      Duration of the benchmark

  -w, --warm-up       Warm-up time before the benchmark

  -u, --uri           Comma-separated list of URIs to request

  -b, --batch         Enable batch mode

  -C, --compress      Compression option (gzip, br, zstd, none)

  -f, --format        Output format (json or markdown)

  -h, --help          Display this help message

## Multiple Domain/URL Tests

Updated 9/9/24 - allow for script to test multiple domain/urls/servers via comma separated list of `-u` URI i.e. `https://domain.com:443,https://domain.com:8443` which will test:

* `https://domain.com:443` web server on port `443`

* `https://domain.com:8443` web server on port `8443`

Output default in JSON format

```

# Batch Mode

`-b` batch mode will take the connections value `-c 400` and divide it into 4 quarters for 4 `h2load` runs incrementing the by each quarter so `-c 100`, `-c 200`, `-c 300`, `-c 400`.

## Batch Mode VPS Markdown Format

Batch `-b` mode with `-f markdown` Markdown formatting:

```

Then run `h2load-plot.gnuplot` to generate chart `output.png`, `output-avg.png` and `output-max.png`

```

./h2load-plot.gnuplot

```

`output.png`

![h2load batch benchmark chart](charts/dedicated/1t-output.png "h2load batch benchmark chart")

`output-avg.png`

![h2load batch benchmark chart - avg response time](charts/dedicated/1t-output-avg.png "h2load batch benchmark chart - avg response time")

`output-max.png`

![h2load batch benchmark chart - max response time](charts/dedicated/1t-output-max.png "h2load batch benchmark chart - max response time")

# Comparison Charts

You can take 2 separate `-b` batch mode runs, renaming the 1st runs' `output.csv` and `output2.csv` files to `1t-output.csv` and `1t-output2.csv` and then edit the labels/legends and run `h2load-plot-vps-vs-dedicated.gnuplot` script to compare 2 runs. Below is comparing above [VPS benchmarks](#batch-mode-vps) and [Dedicated server benchmarks](#batch-mode-dedicated-server) runs with dedicated csv files renamed.

# psrecord

`h2load-bench.sh` added `psrecord` support for local h2load benchmarks tested on local Nginx server to measure local Nginx server's resource usage.
