Libreoffice 4 and 5 are slow to load

[Archer1]

I use Arch Linux, and I installed the libreoffice-fresh package, because it’s the latest, and it didn’t load very fast, in fact it was very slow, so I naturally uninstalled the libreoffice-fresh package and installed the libreoffice-still package, because it’s more stable. While I do get better loading times than libreoffice 5, it’s still VERY slow, and I have the systray quick starter enabled, it doesn’t help. I am using Plasma 5 desktop. here is a post from two ears ago:

3.5 Slow Opening Even Blank Documents

I had this issue with previous versions of Libre Office and I had hoped that it would be resolved with the new version in my new openSuse 12.2 install. But, the problem persists. When opening documents with Libre Office (writer, calc, Impress) the window frame is displayed with solid gray contents for 5 seconds and then the document opens and everything works as expected. Opening a second document produces the same results, a gray window for 5 seconds before the document is displayed. The docum…

Look at the second reply, I turned off the network, and Libreoffice opens up blazing fast. I connect it back again, super slow start.
So clearly, libreoffice is uploading something, maybe anonymous user stats?

Thanks for posting this. I am experiencing exactly the same problem with LibreOffice 5.1.5.2 on a Toshiba Satellite Pro and switching off the network connection solved it immediately. How do we get this message to the developers?

LibreOffice doesn’t try to connect to Internet on startup, at least in my system (Fedora 21). If you are in doubt, Install nethogs command line tool which allows you to detect any network activity happening from your programs. If you suspect that your distro package is the cause, Try downloading LibreOffice from its main site https://www.libreoffice.org/download .

I started using Libre office 4 calc on windows 10 and became terribly slow when loading a document having 12 sheets, but not much data in each sheet, may be 100 rows each. Then I upgraded to 5, but still too slow, it was taking 15 minutes or more to open the spread sheet.
Just now I happened to see this link and tried disconnecting the network and tried to open as the first post above, and it opened the same spread sheet instantly. Puzzled, may be there is some url or something in some pages which it is trying to verify from the net? but still it should not take 15 minutes or more to open.

After me trying out with the network settings, it looks like Libre is searching for the Printer when starting. Whenver the PC which had the printer is switched off and is connected to that network, Libre is becoming too slow to open a file. IF you disconnect from the network, it opens the file immediately or with the network connected, the PC where the printer is connected should be on.
