I can confirm this issue with Libreoffice version 5.1.4. I had a hard time reproducing the slow downs users where reporting to me but managed to recreate the conditions. I narrowed the problem to files listed in "Recent Documents" which are located on a file server (cifs).
With the list populated with about 10 items on the file server and about five open documents the effect is most noticeable. Typing and opening the menus will lag enormously, this will continue until you either clear the list of recent documents or remove it from the menu all together. The difference between a populated and a cleared list is like night and day. The file server in question has decent performance but can take a second to respond if it is very busy. Either way, I do expect the first time listing on the menu to take some time. But the impact on overall performance is very unexpected and likely unintended. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1366519 Title: Incredibly slow editing of documents when connected to network Status in LibreOffice: Invalid Status in libreoffice package in Ubuntu: Fix Released Bug description: When editing a document using LibreOffice, the system locks up after every update typed. Lock up can be up to 30 seconds before control is returned to the user. I have found that this takes place even on documents located on the same physical machine, not just network hosted documents. Problem does not occur if I disconnect form the SSHFS drive. I can understand potential delay when editing a remote document but the connection to an SSHFS file server is affecting editing of locally held documents too.
