Is SHA256 a good step-up to guarantee 'correct data' over fletcher4, or it's only marginally better in real life ?
The checksum is only used to verify that the data is correct (and not to try to correct it) so fletcher4 is fine. The sha256 algorithm does consume noticeable amounts of CPU, particularly since the checksums are computed when a transaction group is saved.
