commit 4782895466055ba5d20de697399ab76f91eee4b6
Author: Andreas Veithen-Knowles <andreas.veit...@gmail.com>
AuthorDate: Sun Feb 1 15:14:08 2026 +0000

    Optimize TestBlob I/O methods using buffered byte arrays
    
    - Implement optimized read(byte[], int, int) in getInputStream using 
Arrays.fill
    - Optimize writeTo to write in 8KB chunks instead of single bytes
    - Use Arrays.fill for efficient buffer initialization
