I am currently playing around with the mapbox for iOS SDK and tried to download a huge offline map. I then noticed when starting the app afterwards, that it takes forever until the app is really loaded. I started investigating with Instruments and found mbgl::OfflineDatabase::initAmbientCacheSize() (running the sql-query in there) taking about 9 seconds in my case. Also, when I initialize MGLOfflineStorage on app launch (to check for unfinished downloads) it will take even longer (hanging in mbgl::OfflineDatabase::getCompletedTileCountAndSize(long long).
Also... while downloading the offline map, my iPhone get really really hot (100% CPU usage while downloading) and in the logs I also saw: QUARANTINED DUE TO HIGH LOGGING VOLUME
