  1. Terrific work by AAYUSH ANAND on benchmarking large-scale configuration pushes across Paramiko and LibSSH. :bullseye:

Large Single Config Push Test (massive_acl_config – 5,206 lines)
Test Configuration:
• Command timeout: 5000s
• Config file: massive_acl_config.txt (5000 ACLs × 50 entries each)
• Operation: Single full configuration push

Results:
• Paramiko: 4486s (74.7 min)
• LibSSH: 4625s (77.1 min)
:right_arrow: Paramiko ~3% faster (139s difference)

Key Findings:
• Both libraries successfully handled extremely large config pushes.
• Required increased timeout (5000s vs. default 2000s).
• No buffer overflow or corruption observed.

Additional Tests:
• Reading large running-config: Paramiko 16.96s vs. LibSSH 15.28s.
• Writing 5206 lines in one push: both timed out after 33+ minutes (device limit).

This is the first time we have clear, quantifiable data comparing the performance of Paramiko and LibSSH under massive config loads — great work setting a benchmark for our future optimization! :clap:
