Performance Lag with Large Logs in Real-time Tail View – Suggestion for Feature Toggle

I encountered some issues while using WindTerm: I often use the tail -fn command to view logs in real-time. However, when the logs become too large, exceeding millions of lines, there's noticeable lag. Could you suggest adding switches to some of the cool features, so that users who prefer a minimalist style or have lower-spec computers can enjoy a better experience?

Start by reproducing the lag with tail -fn and logs containing millions of lines in WindTerm. The issue names no source files, tests, or specific features to toggle, so first identify the affected real-time tail view and define which switches and performance behavior would constitute completion.
