## Performance Optimization Tips for Report Builder

When building custom reports in Alpha Insights, understanding performance best practices is crucial for maintaining fast report load times and a smooth user experience. This guide covers key strategies to optimize your reports and reduce server load.

### Why Report Performance Matters

Reports that take too long to load can:

- Frustrate users and slow down decision-making
- Increase server resource consumption
- Cause timeouts on shared hosting environments
- Impact the performance of your entire WordPress site
- Consume more database resources and slow down other operations

By following these optimization tips, you can create powerful, data-rich reports that load quickly and efficiently.

### 1. Minimize the Number of Widgets

Each widget in your report requires data processing and rendering. The more widgets you add, the longer your report will take to load.

#### Best Practices:

- Start with essential metrics: Only add widgets that directly answer your business questions
- Combine related data: Use multi-metric widgets instead of separate single-metric cards
- Avoid redundancy: Don't display the same data in multiple formats unless absolutely necessary
- Use pagination: For large data tables, enable pagination to limit rows displayed per page
- Recommended widget limit: Try to keep reports under 8-10 widgets for optimal performance

#### Example - Poor Performance:

    ❌ Report with 15 separate metric cards
    ❌ Three different tables showing similar product data
    ❌ Multiple overlapping charts with redundant information

#### Example - Optimized:

    ✅ One multi-metric summary widget with 4-6 key metrics
    ✅ One comprehensive data table with all necessary columns
    ✅ One focused chart highlighting the most important trend

### 2. Optimize Date Range Selection

Long date ranges exponentially increase the amount of data that needs to be processed. Processing years of historical data can significantly slow down report generation.

#### Performance Impact by Date Range:

- Last 7 days: Fast (minimal data processing)
- Last 30 days: Fast to moderate
- Last 3 months: Moderate (noticeable processing time)
- Last 6 months: Slower (increased database queries)
- Last year: Slow (significant processing required)
- All time: Very slow (maximum data processing, can timeout on shared hosting)

#### Best Practices:

- Use appropriate date ranges: Choose the shortest date range that provides meaningful insights
- Default to recent data: Set default views to "Last 30 Days" or "This Month"
- Limit historical analysis: For year-over-year comparisons, use aggregated data or comparison widgets instead of pulling all raw data
- Schedule long-range reports: Run resource-intensive reports during off-peak hours via scheduled emails
- Use date aggregation: When analyzing long periods, group data by week or month rather than day-by-day

#### Tips for Historical Analysis:

If you need to analyze long date ranges:

- Break analysis into smaller time chunks (e.g., quarterly reports instead of annual)
- Use summary metrics instead of detailed tables for older data
- Consider exporting historical data for offline analysis
- Cache frequently-accessed historical reports

### 3. Managing Multiple Data Entities

Reports that pull data from multiple sources (products, customers, orders, ad campaigns, expenses) require more database queries and processing time.

#### What Are Data Entities?

Data entities include:

- Orders and order items
- Products and product variations
- Customers and customer metadata
- Facebook ad campaigns
- Google Ads campaigns
- Expenses and expense categories
- Traffic and session data
- Shipping and payment methods

#### Performance Impact:

    Single entity report (e.g., just products):          Fast
    Two entities (e.g., products + orders):              Moderate
    Three entities (e.g., products + orders + traffic):  Slower
    Four+ entities:                                      Significantly slower

#### Best Practices:

- Focus reports by entity: Create separate reports for products, customers, and marketing rather than one mega-report
- Use pre-built reports: Leverage optimized pre-built reports that are designed for specific entity combinations
- Limit cross-entity joins: Avoid widgets that require complex relationships between multiple entities
- Use filters strategically: Filtering by entity (e.g., specific product category) reduces data volume before processing
- Consider report purpose: Not every report needs every data point - be selective

#### Example - Multiple Entity Optimization:

Instead of one report with:

    ❌ Products + Orders + Customers + Facebook Ads + Google Ads + Expenses

Create focused reports:

    ✅ "Product Performance" - Products + Orders only
    ✅ "Marketing ROI" - Facebook Ads + Google Ads + Revenue
    ✅ "Customer Analysis" - Customers + Orders + Lifetime Value
    ✅ "P&L Dashboard" - Revenue + Expenses + Profit

### 4. Widget-Specific Optimization Tips

#### Data Tables

- Limit rows: Use the "Limit" setting to show top 20-50 results instead of all records
- Enable pagination: Display 25-50 rows per page with pagination controls
- Reduce columns: Only include essential columns in table views
- Use sorting wisely: Pre-sort by the most relevant metric
- Avoid calculated columns: Calculated columns on large datasets can slow rendering

#### Charts and Graphs

- Limit data points: Charts with 50+ data points become cluttered and slow
- Aggregate time-series data: For long date ranges, group by week/month instead of day
- Reduce series count: Limit line charts to 3-5 series maximum
- Use appropriate chart types: Simple chart types (bar, line) render faster than complex ones (bubble, scatter)

#### Metric Cards

- Combine metrics: Use multi-metric cards instead of individual cards
- Disable comparisons when not needed: Period comparisons double the processing required
- Limit comparison cards: Only compare 4-6 metrics, not every data point

### 5. Filtering Strategies for Better Performance

Strategic use of filters can dramatically improve report performance by reducing the data set before processing.

#### Effective Filtering Techniques:

- Apply filters at report level: Set default filters that limit scope (e.g., specific product category)
- Use status filters: Filter by order status to exclude irrelevant data (e.g., "Completed" orders only)
- Category-based filtering: Focus on specific product categories or customer segments
- Traffic source filtering: When analyzing marketing, filter by specific channels
- Pre-filter before export: Apply filters before generating large exports or PDFs

#### Filters That Improve Performance:

- Product category filters (reduces product data)
- Order status filters (excludes pending/failed orders)
- Customer type filters (new vs. returning)
- Geographic filters (specific regions/countries)
- Traffic source filters (specific channels only)
- Campaign filters (specific ad campaigns)

### 6. Server and Hosting Considerations

Report performance is also affected by your server environment and WordPress configuration.

#### Hosting Environment Impact:

- Shared hosting: Limited resources, strict timeout limits - use short date ranges and fewer widgets
- VPS/Cloud hosting: Better performance, moderate timeout limits - can handle standard reports well
- Dedicated hosting: Best performance, flexible timeouts - can handle complex, data-intensive reports

#### Optimization Tips by Hosting Type:

Shared Hosting Users:

- Keep reports under 5-6 widgets
- Use date ranges of 90 days or less
- Limit to 1-2 data entities per report
- Schedule resource-intensive reports for off-peak hours
- Consider upgrading if running large stores (1000+ orders/month)

VPS/Cloud Hosting Users:

- Can use 8-10 widgets comfortably
- Date ranges up to 6 months usually perform well
- Can combine 2-3 data entities
- Monitor server resources and scale as needed

Dedicated/High-Performance Hosting:

- Can handle complex reports with 10+ widgets
- Long date ranges (1 year+) generally work well
- Multiple entity reports perform adequately
- Consider database optimization for very large datasets

### 7. Database Optimization

Over time, your WordPress database can become bloated, affecting report performance.

#### Regular Maintenance:

- Clean transients: Remove expired temporary data from wp_options table
- Optimize tables: Run database optimization tools monthly
- Remove old sessions: Clear expired session data
- Limit revisions: Configure WordPress to limit post revisions
- Archive old orders: Consider archiving orders older than 2-3 years (keep for tax records offline)

#### Alpha Insights-Specific Optimization:

- Cache management: Alpha Insights uses caching to speed up reports - ensure cache is functioning properly
- Clear old cached data: Periodically clear outdated cached report data
- Index optimization: Database indexes improve query performance (handled automatically by Alpha Insights)

### 10. Scheduled Reports for Resource-Intensive Analysis

For reports that require long date ranges or multiple entities, consider using scheduled email reports instead of generating them in real-time.

#### Benefits of Scheduled Reports:

- Reports generate during low-traffic periods
- No waiting for reports to load - receive via email
- Can use longer date ranges without impacting user experience
- Ideal for monthly/quarterly executive reports
- Reduces load on server during business hours

#### How to Schedule Reports:

1. Build your report in the Report Builder
2. Click Schedule Report button
3. Choose frequency (daily, weekly, monthly)
4. Set delivery time (recommend off-peak hours like 2-4 AM)
5. Add recipient email addresses
6. Save schedule

#### Ideal Use Cases for Scheduled Reports:

- Monthly executive summaries with year-to-date data
- Quarterly product performance reports
- Annual tax and financial reports
- Weekly marketing ROI reports with full campaign data
- End-of-month inventory and sales reports
