3x faster setImmediate by andrasq · Pull Request #6436 · nodejs/node

April 27, 2016 20:05use L.create() factory to create access-optimized linkedlist objects
Save the setImmediate callback arguments into an array instead of a closure, and invoke the callback on the arguments from an optimizable function. 60% faster setImmediate with 0 args (15% if self-recursive) 4x faster setImmediate with 1-3 args, 2x with > 3 seems to be faster with less memory pressure when memory is tight Changes: - use L.create() to build faster lists - use runCallback() from within tryOnImmediate - create immediate timers with a function instead of new - just save the arguments and not build closures for the callbacks
Instead of unlinking from the immediate queue immediate on clear, put off the unlink until processImmediate where it's more efficient. 3x faster clearImmediate processing The the benefits stack with the setImmediate speedups, ie total gain of 3.5x with 0 arguments and 4-5x with 1-3 args. Changed the code to defer unlinking from the immediate queue until processImmediate consumes the queue anyway.
Timings for sequential and concurren setImmediate with and without arguments, and set + clearImmediate.
Issues and PRs related to the timers subsystem / setImmediate, setInterval, setTimeout.
Issues and PRs related to the performance of Node.js.

Notable changes: * buffer: Added `buffer.swap64()` to compliment `swap16()` & `swap32()`. (Zach Bjornson) #7157 * build: New `configure` options have been added for building Node.js as a shared library. (Stefan Budeanu) #6994 - The options are: `--shared`, `--without-v8-platform` & `--without-bundled-v8`. * crypto: Root certificates have been updated. (Ben Noordhuis) #7363 * debugger: The server address is now configurable via `--debug=<address>:<port>`. (Ben Noordhuis) #3316 * npm: Upgraded npm to v3.10.3 (Kat Marchán) #7515 & (Rebecca Turner) #7410 * readline: Added the `prompt` option to the readline constructor. (Evan Lucas) #7125 * repl / vm: `sigint`/`ctrl+c` will now break out of infinite loops without stopping the Node.js instance. (Anna Henningsen) #6635 * src: - Added a `node::FreeEnvironment` public C++ API. (Cheng Zhao) #3098 - Refactored `require('constants')`, constants are now available directly from their respective modules. (James M Snell) #6534 * stream: Improved `readable.read()` performance by up to 70%. (Brian White) #7077 * timers: `setImmediate()` is now up to 150% faster in some situations. (Andras) #6436 * util: Added a `breakLength` option to `util.inspect()` to control how objects are formatted across lines. (cjihrig) #7499 * v8-inspector: Experimental support has been added for debugging Node.js over the inspector protocol. (Ali Ijaz Sheikh) #6792 - *Note: This feature is experimental, and it could be altered or removed.* - You can try this feature by running Node.js with the `--inspect` flag. Refs: #7441 PR-URL: #7550
