Has anybody done performance and reliability tests with CRC64 ?
I think it must be a CPU eater. It looks a lot more complex than a CRC32.
Since we need to guard a maximum of 32k bytes for pg pages I would - if at all -
consider to use a 32bit adler instead of a CRC, since that is a lot cheaper
to calculate.
