Calculate memory footprint of cuckoo filter

[ajaybodhe]

Hello,
How can I calculate memory footprint of the cuckoo filter, I am creating.
I am benchmarking this implementation against bloom filter here:

What I am interested is

1. Time taken to insert 500,000 strings
2. Time taken to lookup 1.000,000 strings, out of which 500,000 are the inserted above. So FP will be checked as well
3. Memory footprint

So I need to know how much memory the
type CuckooFilter struct {
buckets []bucket
count uint
}
consumes.

What I am trying:
func (cf *CuckooFilter)GetSize() uintptr {
return unsafe.Sizeof(cf.count) + unsafe.Sizeof(cf.buckets) + uintptr(len(cf.buckets) * 24) + uintptr(len(cf.buckets) * 24 *4)
}

It is shown to be 15mb, may be because each slice element in golang takes 24 bytes additional.
