This site generates useful graphs for various bloom filter values: <https://hur.st/bloomfilter/?n=1e6&p=0.01&m=&k=7>
You may use it to find a preferred optimal value, where `m` is `BloomFilterSize` in bits. Remember to convert the value `m` from bits, into bytes for use as `BloomFilterSize` in the config file.
For example, for 1,000,000 blocks, expecting a 1% false positive rate, you'd end up with a filter size of 9592955 bits, so for `BloomFilterSize` we'd want to use 1199120 bytes.
[Currently](https://github.com/ipfs/go-ipfs/blob/9c194aa7e2febeab0cbd895067d7d90d82b137f9/blocks/blockstore/caching.go), 7 hash functions are used by default, so the constant `k` is 7 in the formula.
As of writing, [7 hash functions](https://github.com/ipfs/go-ipfs-blockstore/blob/547442836ade055cc114b562a3cc193d4e57c884/caching.go#L22) are used, so the constant `k` is 7 in the formula.
