PSMinIO Developer	13091ea1b1	Fix upload performance bottleneck and enhance progress bar text ... 🚀 CRITICAL PERFORMANCE OPTIMIZATION: ✅ FIXED UPLOAD SLOWDOWN ISSUE: • Root cause: Progress reported on EVERY Read() call (thousands per chunk) • Added intelligent progress throttling in ProgressTrackingStream • Only report progress every 1% or 1MB (whichever is smaller) • Minimum 8KB threshold to prevent excessive updates • Massive reduction in progress callback overhead ⚡ PERFORMANCE IMPROVEMENTS: • Before: Progress callback on every 4KB-64KB read = 1000+ calls per chunk • After: Progress callback every 1MB or 1% = ~64 calls per 64MB chunk • 15x-20x reduction in progress overhead • Maintains smooth progress bars without performance penalty ENHANCED PROGRESS BAR TEXT: Added 'Counter of Counter' format to chunk progress Before: 'Part 23: 32.1 MB/64.0 MB' After: 'Part 23 of 74 - 32.1 MB/64.0 MB' Better context for users about overall progress TECHNICAL IMPLEMENTATION: Added _reportingThreshold and _lastReportedBytes to ProgressTrackingStream Throttled progress reporting while maintaining accuracy Updated UploadPart method signature to include totalParts Preserved final progress report at 100% completion EXPECTED RESULTS: Fast, consistent upload speeds on high-bandwidth connections Smooth progress bars without performance degradation Better user experience with contextual progress information Scalable to large files without slowdown Critical fix for multipart upload performance!	2025-07-14 22:50:50 -04:00
PSMinIO Developer	27c2aca2a9	Implement 3-layer progress tracking for multipart uploads ... � 3-LAYER PROGRESS TRACKING: ✅ ENHANCED PROGRESS VISIBILITY: • Layer 1: Collection Progress - Overall multipart upload operation • Layer 2: File Progress - Current file being uploaded with parts • Layer 3: Chunk Progress - Individual chunk upload with streaming � STREAMING IMPLEMENTATION: • Created ProgressTrackingStream for real-time chunk upload progress • Replaced ByteArrayContent with StreamContent for better memory usage • Maintains MD5 calculation for data integrity • Progress updates during actual data transfer � PROGRESS HIERARCHY: • Collection Progress (ID: 1) - 'Multipart Upload Collection' • File Progress (ID: 2, Parent: 1) - 'File Upload' with speed/ETA • Chunk Progress (ID: 3, Parent: 2) - 'Uploading Chunk' with bytes transferred ✅ TECHNICAL IMPROVEMENTS: • Real-time progress during HTTP upload (not just after completion) • Proper parent-child progress relationship • Memory-efficient streaming approach • Maintains existing MD5 integrity checking • Compatible with parallel chunk uploads � USER EXPERIENCE: • See overall multipart upload progress • Track current file upload with speed metrics • Watch individual chunks upload in real-time • Better visibility into long-running operations Now multipart uploads show comprehensive 3-layer progress tracking!	2025-07-14 21:29:10 -04:00
