Optimize system performance and add comprehensive progress indicators
Feature Request
Summary
Optimize CryptoSlut's performance across all operations and implement comprehensive progress indicators to provide users with clear feedback on system activities. This enhancement will improve user experience by reducing wait times and providing transparency into long-running operations.
Problem Statement
Currently, CryptoSlut performs well functionally but has several performance and user experience issues:
Performance Issues:
- Market scanning can be slow when processing many symbols
- Data fetching operations lack parallelization opportunities
- Database queries could be optimized for large datasets
- Strategy analysis could be optimized for real-time processing
- Memory usage could be more efficient for long-running operations
User Experience Issues:
- No progress indication during data fetching or analysis
- Users don't know what's happening during long operations
- No visual feedback for scanning progress
- Unclear system status during startup and monitoring
- Limited visibility into performance bottlenecks
This creates frustration for users who don't know if the system is working or stuck, and limits scalability for larger datasets.
Proposed Solution
Implement comprehensive performance optimizations and progress indication system:
Performance Optimizations:
- Parallel Data Fetching: Concurrent API calls for multiple symbols
- Intelligent Caching: Smart cache invalidation and update strategies
- Database Optimization: Query optimization, indexing, and connection pooling
- Memory Management: Efficient data structures and garbage collection
- Strategy Optimization: Vectorized calculations and batch processing
- API Rate Limiting: Intelligent throttling to maximize throughput
Progress Indication System:
- Real-time Progress Bars: Visual progress for all long operations
- Status Updates: Clear messages about current activities
- Performance Metrics: Speed, throughput, and timing information
- Error Handling: Clear error messages with recovery suggestions
- Startup Feedback: Detailed initialization progress
- Live Monitoring Stats: Real-time performance dashboards
Alternative Solutions
- Use third-party progress libraries (less integrated, limited customization)
- Simple time estimates (less accurate, no real progress tracking)
- Status logging only (less visual, harder to track)
- Performance profiling tools (development-only, not user-facing)

results = await asyncio.gather(*tasks, return_exceptions=True)
Progress Tracking:
from rich.progress import Progress, SpinnerColumn, TimeElapsedColumn
with Progress() as progress:
task = progress.add_task("Scanning markets...", total=len(symbols))
for symbol in symbols:
# Process symbol
progress.update(task, advance=1)
Performance Monitoring:
class PerformanceMonitor:
def track_operation(self, operation_name):
# Track timing, memory, and throughput
return OperationContext(operation_name)
