In reality, the effect of JIT compilation is broader - execution can slow down for up to ~1ms even for sljit, because of other related things, mostly cold processor cache and effects of increased memory pressure (rapid allocations / deallocations related to code generation and JIT compilation). Therefore, on systems executing a lot of queries per second, it's recommended to avoid JIT compilation for very fast queries such as point lookups or queries processing only a few records. By default, jit_above_cost parameter is set to a very high number (100'000). This makes sense for LLVM, but doesn't make sense for faster providers.
