This may be the case only on Windows, but Microsoft has repeatedly claimed (and shown) that scheduling timers somehow "wakes up" the computer from its low-power state. Thus repeatedly scheduling timers keeps it in some kind of "high alert" state where it's never ready to settle down into low-power because it knows that within a few milliseconds it'll need to perform the appropriate timer interrupt to fire the task. This may be Windows-specific, or IE-specific, or even just FUD (i.e., if IE was smarter it could implement timers as efficiently as it does `setImmediate`). I am not really in a position to say. But it is the reality today with IE10 and IE11. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
