I have LibreCAD on a wired 1GB network. Using the same AutoCAD DWG source files I opened then saved them as DXF files to two different locations. The first location was a network share and it took as much as 10 minutes to save. The second location was the local hard drive and it took no more than about 10 seconds to save.
Any idea of why the difference? It is really irritating to have LibreCAD autosave and take minutes to save after making a few changes.
