High memory usage

[YodaEmbedding]

Describe the bug
Memory usage nominally between 0.6 GB -- 1.4 GB.

Steps to reproduce

1. Open a markdown document in nvim. This starts ltex-ls with 0.6 GB -- 0.9 GB RAM usage.
2. To increase it further to 1.4 GB, open a few more documents.

EDIT: Even more minimal is to just start ltex-ls on the CLI:

ltex-ls

Expected behavior
Significantly less memory usage. Something like 0.1 GB JVM + 0.2 GB app + 0.01 GB / document.

LTeX configuration
Please paste all configuration settings starting with ltex. from your settings.json. You can help us by temporarily removing some irrelevant settings from your settings.json and see if the bug still occurs.

Defaults.

• ltex-ls: 16.0.0
• Java: openjdk version "21" 2023-09-19

I encountered the same problem, memory consumed by OpenJDK Platform binary increases dramatically between 0.8 - 1.4 GB.
While I killed the OpenJDK Platform binary in Windows Task Manager, the Client ltex quit with code 1, then the memory usage drops.

LanguageTool recommends 4 GB as heap size, see https://github.com/languagetool-org/languagetool/tree/master/languagetool-standalone
1.4 GB actual memory usage seems to be OK in my opinion.
