| Feature | Internal Mechanism | |---------|--------------------| | | Separate threads for sending, ACK processing, disk I/O, encryption. | | Asynchronous I/O | Overlapped reads/writes to keep the UDP pipe full. | | Disk read-ahead | Pre-fetches next file blocks into memory. | | Delta transfer | Compares checksums of local vs remote file; sends only changed blocks (rsync-like). | | Bandwidth throttling | Token bucket implemented inside the send loop. | filecatalyst internal
