First, use wineboot instead of winecfg to set up the WINEPREFIX. It's the right tool for it. Second, when initialising WINEPREFIX, use output pipes instead of CombinedOutput. The latter will wait for *all* output to be copied to a buffer, including the output from grandchildren processes. Since wine starts wineserver automatically, and wineserver lingers for three seconds by default, this is bad. We would waste three seconds waiting for wineserver doing nothing, and then the next wine call (to start the app) would need to start wineserver all over. Instead, with pipes we can get cmd.Run to only wait for the parent process to finish. wineserver stays running but we don't care. And, when we start the gio app, we very likely reuse the same wineserver process. Third, disable wine-gecko and wine-mono. This ensures we don't get stuck if they're not installed, and speeds up wineboot by avoiding work we don't need. The time to set up WINEPREFIX goes down form ~6s to ~1s, and the overall subtest run-time goes down from ~10s to ~3s. Finally, copiously document all of the precious data I've gathered above after hours of debugging. Signed-off-by: Daniel Martí <mvdan@mvdan.cc>
