SUMMARY *** My .ssh/config is over 23000 lines long. About half a year ago (possibly earlier), after the next update, launching Konsole began to take more than 10 seconds. I recently took the time to find out the reason. The reason turned out to be the SSH Manager plugin. Every time you start Konsole, it reads .ssh/config and generates .config/konsolesshconfig and it seems to do this in a far from optimal way. *** STEPS TO REPRODUCE 1. Generate large .ssh/config: for i in $(seq 1 10000); do echo -e "Host test-$i\nHostname 127.0.0.1\n"; done > ~/.ssh/config 2. Launch Konsole OBSERVED RESULT The delay from the moment the Konsole starts until the window appears takes more than 10 seconds. EXPECTED RESULT Konsole should start in less than a second.
