When is Money Laundering not a GDPR right to be forgotten, or is the level of surveillance too great? Generally HW is the main factor with performance, then quality of coding and functionality that exists. For example in MS SQL BulkInsert is fastest ie importing from a txt/csv file then batch inserts then single record inserts. Now the next factor is how many records need to be inserted? Companies like Experian have been using a custom ISAM (dbase/clipper type) database where Mon-Sat users can read the data and all data is updated on Sunday. It was the only way to serve a country wide levels of users with 90's HW. It also meant the speed gains were found by doing stuff in RAM then writing out data in a serial manner to disk. Things havent changed that much in 30 years, RDBMS systems are just another layer between HW and the end users app!
