    I’ve been using the OpenLiteSpeed server and LiteSpeed Cache for a week, and during this time I noticed a few issues:

    1. On PageSpeed Insights, the Time to First Byte (TTFB) increased from 0.8s to 1s, and Interaction to Next Paint (INP) also went up from 80ms to 87ms.
    2. Based on the time it takes me to open a single page, it feels noticeably slower than before; I previously used NGINX&Apache with WP Fast Cache.

    I used Presets->Advanced (Recommended) and didn’t make any other changes.

    I want to know the reason for the increase in TTFB and what changes I need to make to improve TTFB.

    Thank you!
