A 10x slowdown is actually pretty bad for --tool=none, especially after transation chaining landed last month. If the system is steady-stating at 10x slowdown with --tool=none, that's a bug that I'd like to know about. Starting large apps (apache, etc) requires jitting tens or hundreds of thousands of basic blocks and can take several seconds, which makes these short-running tests unrepresentative of the steady state performance. Because of that, [email protected], you might get a better result by arranging your tests to do more useful work per process-startup.
