It did when I put in that comment in 2009. At that point in time, the routine was very hot. Subsequent optimizations have enabled us to completely bypass that routine. The code in question now only runs as a verification step when compiled with -DSQLITE_DEBUG. So these days the initialization does not matter. But the point is the same. Sometimes an unnecessary initialization in a hot routine can make a big difference in performance. -- D. Richard Hipp drh at sqlite.org
