I’ve been having an issue with poor responsiveness in Kate (currently 26.04.3) when editing files on a remote system connected via sshfs.
The remote machine is on another continent and has a ~400ms round-trip. When I open a file on that machine with Kate, my editor will intermittently freeze for about that long. This happens most reliably when entering a new line. The line does appear, but I cannot enter any text for about half a second. If I type during this time, the text does appear after the editor catches up. The same thing happens intermittently in other situations I’ve yet to notice a pattern for.
I’m assuming (baselessly) that Kate is accessing the file on disk when this occurs, but I’m not sure why that would be happening so often. I can’t see any setting that would obviously cause such frequent disk access. I’d appreciate any suggestions for where to start with troubleshooting this.
