Troubleshooting macOS Sonoma Upgrade Issues on MacBook Pro 13" (mid-2012)

Hi! I'm seeking assistance with resolving performance issues following an upgrade from macOS Monterey to Sonoma on my MacBook Pro 13" (mid-2012) using OpenCore Legacy Patcher.

The system's performance has noticeably declined compared to Monterey. It has become more laggy and the startup has gone very slow. However, I'm hesitant to follow random steps I fpund on YouTube without proper guidance to avoid further complications.

Would anyone be kind enough to share their expertise on troubleshooting these issues? Any insights into optimizing its current performance would be greatly appreciated.

Unit: MacBook Pro 13" mid-2012 Model: A1278 Current OS: macOS Sonoma ver. 14.4.1
