📦 Installation

pip install performance-profiler-optimizer

Or install from source:

git clone https://github.com/yourusername/performance-profiler-optimizer.git
cd performance-profiler-optimizer
pip install -e .

🚀 Quick Start

Basic Performance Profiling

from performance_profiler import PerformanceProfiler

profiler = PerformanceProfiler()

@profiler.profile
def my_function():
    return sum(range(1000000))

my_function()
profiler.print_results()

Memory Profiling

from performance_profiler import MemoryProfiler

memory_profiler = MemoryProfiler()
memory_profiler.enable()

@memory_profiler.profile_memory
def memory_intensive_task():
    return [i**2 for i in range(1000000)]

memory_intensive_task()
memory_profiler.print_results()

Line-by-Line Analysis

from performance_profiler import LineByLineProfiler

line_profiler = LineByLineProfiler()

@line_profiler.profile_lines
def complex_function():
    data = [i for i in range(10000)]
    filtered = [x for x in data if x % 2 == 0]
    return sum(filtered)

complex_function()
line_profiler.print_results(top_n=15)

Auto-Optimization Suggestions

from performance_profiler import OptimizerEngine

optimizer = OptimizerEngine()

# Analyze code
code = """
def inefficient():
    result = []
    for i in range(1000):
        result.append(i * 2)
    return result
"""

suggestions = optimizer.analyze_code(code)
optimizer.print_suggestions(suggestions)

Before/After Comparisons

from performance_profiler import ComparisonEngine

comparator = ComparisonEngine()

def before_optimization(n):
    result = ""
    for i in range(n):
        result += str(i)
    return result

def after_optimization(n):
    return ''.join(str(i) for i in range(n))

result = comparator.compare_functions(
    before_func=before_optimization,
    after_func=after_optimization,
    args=(1000,),
    iterations=100
)
comparator.print_comparison(result)

Bottleneck Detection

from performance_profiler import BottleneckDetector

detector = BottleneckDetector()

@detector.detect_bottlenecks
def slow_function():
    result = 0
    for i in range(1000):
        for j in range(1000):
            result += i * j
    return result

slow_function()
detector.print_bottlenecks()

Historical Tracking

from performance_profiler import HistoricalTracker

tracker = HistoricalTracker(db_path="performance.db")

@tracker.track
def monitored_function():
    return sum(range(100000))

# Run multiple times to build history
for _ in range(10):
    monitored_function()

# View history and trends
tracker.print_history("monitored_function", limit=10)
trend = tracker.get_trend("monitored_function", "execution_time")
print(f"Performance trend: {trend['trend']}")
