Yonik Seeley commented on LUCENE-3037:
--------------------------------------

This should be even faster:
{code}
 public static int log(int x, int base) {
   assert base>=2;
   int ret = 0;
   long n = base; // needs to be a long to avoid overflow
   while (x >= n) {
     n *= base;
     ret++;
   }
   return ret;
 }
{code}
