> Many programs use fopen(), fread(), and fwrite() to create and manage files of data in home-grown formats. SQLite works particularly well as a replacement for these ad hoc data files. Contrary to intuition, SQLite can be faster than the filesystem for reading and writing content to disk.
I’m open to being convinced otherwise, but I would expect that inserts/s would vary a bunch by filesystem.
But I do agree that local nvme with any file system is absurdly better than what you’re likely to find in typical cloud envs.
