   Go vs Java benchmark: 
https://github.com/apache/datasketches-characterization/pull/89
   
   code:
   
   ```go
   func BenchmarkHashAndScreen(b *testing.B) {
        b.Run("most hashes passes", func(b *testing.B) {
                ht := NewHashtable(10, 10, ResizeX2, 1.0, MaxTheta, 
DefaultSeed, true)
                b.ReportAllocs()
                b.ResetTimer()
                for i := 0; i < b.N; i++ {
                        _, _ = ht.HashInt64AndScreen(int64(i))
                }
        })
   
        b.Run("hashes exceed theta", func(b *testing.B) {
                ht := NewHashtable(10, 10, ResizeX2, 0.001, 1000, DefaultSeed, 
true)
                b.ReportAllocs()
                b.ResetTimer()
                for i := 0; i < b.N; i++ {
                        _, _ = ht.HashInt64AndScreen(int64(i))
                }
        })
   }
   ```

   Sorry for not considering performance in hot path when i wrote code and 
Thank you for accepting breaking change.
