> LineFileDocs(random) is very slow, even to open. It does a very slow "random skip" through a gzip compressed file.
> For the analyzers tests, in LUCENE-9186 I simply removed its usage, since TestUtil.randomAnalysisString is superior, and fast. But we should address other tests using it, since LineFileDocs(random) is slow!
> I think it is also the case that every lucene test has probably tested every LineFileDocs line many times now, whereas randomAnalysisString will invent new ones.
> Alternatively, we could "fix" LineFileDocs(random), e.g. special compression options (in blocks)... deflate supports such stuff. But it would make it even hairier than it is now.
