Performance analysis indicates that SQLite spends very little time doing bytecode decoding and dispatch. Most CPU cycles are consumed in walking B-Trees, doing value comparisons, and decoding records—all of which happens in compiled C code. Bytecode dispatch is using less than 3% of the total CPU time, according to my measurements.
So at least in the case of SQLite, compiling all the way down to machine code might provide a performance boost 3% or less. That’s not very much, considering the size, complexity, and portability costs involved.

Sometimes, performance just doesn’t matter. If I make some codepath in Ruff 10x faster, but no one ever hits it, I’m sure it could get some likes on Twitter, but the impact on users would be meaningless.
And yet, it’s good to care about performance everywhere, even when it doesn’t matter. Caring about performance is cultural and contagious. Small wins add up. Small losses add up even more.
