--- Comment #5 from [email protected] --- I did some more research on this issue after realizing that LibreOffice has a "Open Remote" feature, which was supposed to have a "Windows Share" option. However, on Windows installation there is no such option. Then I decided to try this on Linux. I installed Ubuntu 22.04 Desktop on VirtualBox virtualization environment on my Windows 10 Pro 22H2 system. Then I opened the previously mentioned OOME_4_0.odt file from Windows SMB share and I got the following results when saving: Saving takes: 35 s. over 10/10Mbit VDSL 30 s. over 200/20 4G wireless. Download traffic was reduced from 16MB to just 0,1MB and the upload traffic remained the same 8MB as expected. So, the overhead download traffic was reduced to just a small fraction of what it was on the Windows platform and as a result the slowest network (10/10) connection saw also a massive 56% reduction in the saving time. The much faster internet 200/20 connection saw small 14% decrease in the saving time. This result is expected because the reductions come from reduced overhead download traffic and the faster connection is already mainly limited by the LO serialization process, not the network speed. I also noticed that when opening the file from Ubuntu file manager, LibreOffice recognized this as remote file (shows (remote) on the window title) and the saving is also equally fast in that situation. As conclusion, this issue mainly affects Windows users with slow internet connections.
