--- Comment #12 from Tim Allison <talli...@apache.org> ---
Hackery of code:
Random r = new Random();
int sz = 100000;
int iterations = 100;
long absents = 0;
long gets = 0;
long totalElapsed = 0;
int warmup = 10;
int observations = 0;
for (int it = 0; it < iterations; it++) {
long start = System.currentTimeMillis();
System.out.println("iteration " + it);
int[] ints = new int[sz];
for (int i = 0; i < sz; i++) {
ints[i] = Math.abs(r.nextInt());
}
// BitSet bs = new BitSet();
RoaringBitmap rb = new RoaringBitmap();
for (int i = 0; i < sz; i++) {
/*bs.set(ints[i]);
long absent = bs.nextClearBit(ints[i]);
absents += absent;
if (bs.get(Math.abs(r.nextInt()))) {
gets++;
}*/
rb.add(ints[i]);
long absent = rb.nextAbsentValue(ints[i]);
absents += absent;
if (rb.contains(Math.abs(r.nextInt()))) {
gets++;
}
}
if (it > warmup) {
long elapsed = System.currentTimeMillis() - start;
System.out.println(absents + " " + gets + " " + elapsed);
totalElapsed += elapsed;
observations++;
}
}
System.out.println(totalElapsed + " total ms, " +
(double) totalElapsed / (double) observations + " avg ms");
