Performance Issues

Optimize app performance and resolve speed problems.

Slow Loading Times

Section titled “Slow Loading Times”

App pages loading slowly:

Check performance:

  • Expected load time: < 2 seconds
  • Actual: 5-10 seconds

Causes:

  1. Large number of files (1000+)
  2. Slow internet connection
  3. Browser cache full
  4. Too many browser tabs open
  5. Computer resources low

Solutions:

  1. Enable pagination: Settings → Display → Items per page: 50
  2. Clear browser cache: Ctrl+Shift+Del
  3. Close unused tabs
  4. Use Chrome or Firefox (faster)
  5. Filter/search instead of browsing all

File Upload Slow

Section titled “File Upload Slow”

Uploads taking very long:

Check upload speed: Test: speedtest.net Required: 5+ Mbps upload Your speed: ? Mbps

Improve:

  1. Use wired connection (not WiFi)
  2. Close bandwidth-heavy apps
  3. Upload smaller batches (20-30 files)
  4. Upload during off-peak hours
  5. Contact ISP if consistently slow

Large files:

  • 1 GB @ 10 Mbps: ~13 minutes
  • 5 GB @ 10 Mbps: ~67 minutes
  • Use FTP for 100+ GB

Download Speed Slow

Section titled “Download Speed Slow”

Customers report slow downloads:

Check CDN: Settings → Performance → CDN Status: Should be “Enabled”

Solutions:

  1. Enable CDN: Settings → Performance
  2. Check file size (compress if >500 MB)
  3. Use optimized formats (MP4 not AVI, PDF not TIF)
  4. Verify R2/storage provider status
  5. Test from multiple locations

Monitor: Analytics → Performance → Download Speed Target: 10+ MB/s average

Database Slow Queries

Section titled “Database Slow Queries”

Search and filters slow:

Symptoms:

  • Search takes 10+ seconds
  • Filters timeout
  • Page hangs

Fix:

API Rate Limiting

Section titled “API Rate Limiting”

“Too many requests” error:

Error: HTTP 429 - Too Many Requests

Limits:

  • 1000 requests/hour
  • 100 requests/minute burst

Solutions:

  1. Slow down API requests
  2. Implement backoff/retry logic
  3. Cache responses
  4. Upgrade to higher tier (Enterprise)

Code example:

if (response.status === 429) {
  const retryAfter = response.headers.get('Retry-After');
  await sleep(retryAfter * 1000);
  // retry request
}
