After testing I fully agree with this compromise. Below are the latencies I reached with no xruns during a 10min rakarrack session on my test laptop (Dell Vostro V13 with a TI firewire card): -generic: 16ms -lowlatency: 4ms (@2ms: tons of xruns) -realtime: 4ms (@2ms: many xruns) To put it simply: -lowlatency all the way! It delivers impressive results for maintenance requirements way lower than -realtime (or -rt even more), meaning less work for maintainers and new kernel candy for users. A few diehard performance fans may appreciate a PPA with -rt, but if there must be one sustainable and supported priority, it is -lowlatency.
