See T275319: Change $wgMaxArticleSize limit from byte-based to character-based for current discussions about expanding $wgMaxArticleSize.

User Vladis13 did a great job importing some public domain texts in Russian Wikisource. He also prepared a folder with texts that were too big: https://disk.yandex.ru/d/QjFXyEiY0t7Qvw

I analyzed that folder and created this chart with file size buckets:

Conclusion: If the maximum article limit will be increased to 4 MB, he can automatically upload 314 books into Russian Wikisource. There are still 14 books that are larger than 4 mb, but at this point we can deal with those manually and split them into parts. But it's impossible to do it 300 books.

Tagging with the same tags as T275319: Change $wgMaxArticleSize limit from byte-based to character-based. This will require approval from Performance-Team at least.

I'd like to explicitly link @Krinkle's comment from T275319#7947012 here. It applies to this case as well, and it perfectly describe where the issue with raising is.

It would be good to look at the performance of pages at https://ru.wikisource.org/wiki/%D0%A1%D0%BB%D1%83%D0%B6%D0%B5%D0%B1%D0%BD%D0%B0%D1%8F:%D0%94%D0%BB%D0%B8%D0%BD%D0%BD%D1%8B%D0%B5_%D1%81%D1%82%D1%80%D0%B0%D0%BD%D0%B8%D1%86%D1%8B

This is one of the longest pages in Russian Wikisource: https://ru.wikisource.org/wiki/%D0%A4%D0%B8%D0%BD%D0%B8%D0%B0%D1%81_%D0%A4%D0%B8%D0%BD%D0%BD,_%D0%B8%D1%80%D0%BB%D0%B0%D0%BD%D0%B4%D1%81%D0%BA%D0%B8%D0%B9_%D1%87%D0%BB%D0%B5%D0%BD_%D0%BF%D0%B0%D1%80%D0%BB%D0%B0%D0%BC%D0%B5%D0%BD%D1%82%D0%B0_(%D0%A2%D1%80%D0%BE%D0%BB%D0%BB%D0%BE%D0%BF)/%D0%94%D0%9E
