The `eglot-events-buffer-size` setting disables the `eglot-events-buffer` when 0, enabling more consistent performance on long running emacs instance. Default is 2000000 lines. After each new event the events buffer is pretty printed as a whole, which causes steady performance decrease over time. Quite a bit of CPU is spent on pretty priting and Emacs GC is put under high pressure.
