Emile, please keep the newsgroup in the loop.
That statement does not make sense, are you telling us that each of the 22 small documents takes long to load into LyX? I.e. you load the master document and then right click onto the link of a sub document and then click on Edit? Or do you mean making a PDF? I would very strongly agree with Jean-Marc to send *HIM*, ie the LyX authors the whole document(s) so they can see what the cause is. I also would strongly suggest you upgrade your Windoze to 10 if you can't switch to a proper computer like a Mac or a Linux box. el On 2016-07-26 16:00, emile lunardon wrote: > First it was one big document then when I had the loading time > problem with LyX2.2.0 I organized the document in a small main > document and several sub-documents (22) but the loading time remains > very high except using LyX2.1.5 > > 2016-07-26 15:53 GMT+02:00 Dr Eberhard Lisse <nos...@lisse.na>: > > Is this one yuuge document or one with many includes? > > el > > On 2016-07-26 11:13, emile lunardon wrote: [...] > > I have a very big document (~100 Mo Pdf mainly of text with ~ > > 15000 pages) which was originally written with LyX 2.1 .
