Benchmark Analysis Performance — benchmark

Test analysis speed and memory usage

Usage

benchmark_analysis(
  scale = "huc8",
  year = 2016,
  nutrients = "nitrogen",
  n_runs = 3,
  include_wwtp = TRUE
)

Arguments

scale: Character. Spatial scale
year: Numeric. Year to test
nutrients: Character vector. Nutrients to analyze
n_runs: Integer. Number of benchmark runs (default: 3)
include_wwtp: Logical. Include WWTP processing

Value

List with timing statistics and memory usage

Examples

# \donttest{
# Benchmark HUC8 analysis - use smaller scale for faster testing
benchmark <- benchmark_analysis(
  scale = "county",  # Use county for faster testing
  year = 2016,
  nutrients = "nitrogen",
  n_runs = 2  # Reduce runs for faster testing
