Profiling
v8 v9 39 39 General guidelines: 40 40 * start with a small delay (ie: {{{-d 2}}}) to skip the initial setup, potentially longer if you start a server and then also need to connect the client before profiling 41 * if testing locally (which is generally more convenient), don't forget to turn off mmap with {{{--no-mmap}}} 41 42 * when comparing versions/changes/settings: use the runtime parameter to ensure that each run will last for exactly the same amount of time - this makes it easier to compare the labels using absolute values, and script the whole thing so the client connects at exactly the same time if profiling the server 42 43 * focus on one thread at a time - there is not much overlap/impact between different threads
