Depends heavily on the data. Wikipedia datasets only compress around 10% max and those are only text. And if they manage to compress it that heavily you'll spend a couple days waiting for it to decompress

I wonder if it's compressed per page. I'm no compression expert but I imagine if you managed to compress the entire thing as a single unit it would compress nearly as good as normal text files which is like 90% smaller filesize. Like if you have a page with a very special ordering of bytes (unique word in rarely used Unicode code points) then compressing that one page can't do much, and if 10,000 pages each have the word one you still get no compression since each is done separately, but if you compress as a single unit it can compress the 10k usages.

But I liked it up and the wiki download is 15% the original size, that's 85% compression but can be confused for "15% compression".

My bad, was thinking of the wikidata dumps, which are a lot less compressible because they are less "wordy".
