 Mike Kaganski 2020-02-21 16:48:02 UTC Created attachment 158084 [details] An XLSX with an external link in named range, which is not referenced anywhere The attachment contain no data on a single empty sheet; the only thing that is defined in the document is a named range that references a file on a network share with Windows UNC name "\\path\to\file.xls" (and an invalid reference there). The range is not used anywhere in the document, it's only defined. When the document is opened, LO shows an infobar telling that automatic updates of external links are disabled (with default settings). The problem is that if the update is allowed, soffice.bin tries to access the network path. This is a performance issue: if the share is unavailable, the request to access the file must time out before LibreOffice can proceed. Given that the data in not referenced anywhere, the network access is useless. The time is spent in Content::isFolder (ucbhelper/source/client/content.cxx). Eike: do you think it's possible to not try to access not referenced data? I suppose that could also speed up documents that link to local files, too.
