Since about LO 7.0 I experience severe lags on macOS when using LO to work with files that are stored on a network share, mounted via SMB. Lags ("rolling ball") occur when using the cursor-keys to move the cursor for the first time (!) after a document has been opened (note: not first time after LO has been launched, but for each document) and when saving the document to disk. Lags have been experienced with Writer, Calc and Impress (other LO applications have not been tested). Lags seem to be less when "Recent Documents" has been cleared (cp. https://ask.libreoffice.org/t/libreoffice-periodically-accesses-files-in-recent-list-causing-freezes/9240).

Connection speed can be ruled out as a cause, although lags are more severe when accessing files through VPN-tunnel compared to gigabit ethernet, but still occur when connected to ethernet. 

Interestingly, the Windows version of LO (running on a Win7 machine in the same network) does *not* show similar symptoms.

Sorry, not a Win7, but a Win10 machine (my mistake).
