The SQLite performance improved a lot with Debian 8 and since then has been largely flat.

With the SQLite Speedtest is a more measurable difference when it comes to the default CPU security mitigations having hurt the performance but otherwise the numbers there too are largely flat.

The EXT4 random read performance was at its best around Debian 8.

Random writes have also been trending lower with new releases, even if disabling the default CPU security mitigations.

Sequential read performance is at least improved since Debian 10 and offered similar performance on Debian Testing.

Sequential write performance meanwhile dropped sharply since Debian 10.

The CompileBench performance has been improving with time and is helped out if booting with mitigations=off
