That mainly depends on TouchWiz versus AOSP. TW definitely takes longer, maybe 5-10 minutes total, although 10 minutes is probably pushing it; AOSP just a couple of minutes, especially now that a lot of ROMs are taking advantage of devices with multiple cores to speed up boot time. In general, if your boot takes more than ten minutes, then something has gone sideways, and waiting longer isn't going to make miracles happen-I've seen people post about how they waited an hour or more hoping for something to fix itself, when clearly that isn't happening! Also, if you choose to run AOSP (far superior to TW in my opinion, emphasis on "opinion"), and you enable ART after the initial boot, the changeover does take a long time due to reconfiguring each installed app for the new runtime.
