Buffer pool configured: 0.12 GB (134217728 bytes), page_size=16384

Window #1 (~11s): read_requests/s=149681  phys_reads/s=1211  hit_ratio=0.9919  pool(total/data/free)GB=0.12/0.12/0.00  free%=0.67  Threads_running=14
Window #2 (~10s): read_requests/s=100799  phys_reads/s=461  hit_ratio=0.9954  pool(total/data/free)GB=0.12/0.10/0.02  free%=12.19  Threads_running=16

Averages: read_requests/s=125240  phys_reads/s=836  hit_ratio=0.9936

Interpretation:
- Aim for hit_ratio ≥ 0.999 with phys_reads/s near 0 under normal load.
- If FREE% ≈ 0 and phys_reads/s > 0 → buffer pool too small.
- If hit is good but pages slow → check slow log and indexes.
