Katsem File Upload Hot Guide

Edit /etc/katsem/katsem.conf:

hot_upload_enabled = true
hot_cache_size_mb = 4096   # 4GB RAM cache
hot_chunk_size_kb = 2048   # 2MB chunks for low latency
hot_parallel_streams = 8
hot_ttl_seconds = 3600      # File stays in hot cache for 1 hour

Not every file transfer requires the "hot" treatment. Reserve it for these scenarios: katsem file upload hot

For routine tasks (e.g., uploading team photos or PDF receipts), use standard ("cold") upload profiles to free up hot slots. Edit /etc/katsem/katsem

Output: Visual heat overlay showing “hottest” 30% of the file content.

You should see the Katsem Upload Interface.

We conducted a benchmark using a 1GB file across three scenarios: Not every file transfer requires the "hot" treatment

| Metric | HTTP/2 Upload | Standard Katsem | Katsem Hot Upload | |--------|--------------|----------------|------------------------| | Upload time (1Gbps) | 8.2 sec | 6.1 sec | 3.4 sec | | Time to file availability | 9.1 sec | 7.0 sec | 0.45 sec | | CPU usage | 12% | 18% | 29% (acceptable for hot) | | Retransmission rate | 3.2% | 1.1% | 0.3% | | Concurrent hot files | N/A | N/A | Up to 500 |

As shown, the "hot" feature cuts availability delay by over 90%, making it ideal for real-time analytics, live video editing, and emergency data recovery.
