Node: Ignition + TurboFan: Node.js benchmarks
- Version: 8.0
- Platform: Windows 7 x64
- Subsystem: v8, benchmark
This commit in the v8/node/vee-eight-lkgr has turned the new Ignition+TurboFan pipeline on by default. To see the performance impact, I've built vee-eight-lkgr before and after this commit and have started common Node.js benchmark suites with them.
Both builds have these same versions:
{ http_parser: '2.7.0',
node: '8.0.0-pre',
v8: '5.9.0 (candidate)',
uv: '1.11.0',
zlib: '1.2.11',
ares: '1.10.1-DEV',
modules: '56',
openssl: '1.0.2k',
icu: '58.2',
unicode: '9.0',
cldr: '30.0.3',
tz: '2016j' }
As my machine is not a fast one, I will post the results piecemeal.
UPD. All suites are complete.

Yikes... those performance hits... especially for Uint8Array.

There is still improvements being made in the area of TypedArrays: https://bugs.chromium.org/p/v8/issues/detail?id=5977

Hmm yeah I think we should definitely keep an eye on that before merging. We use UInt8Array a lot.

@bmeurer @psmarshall could we keep an eye on this?
hashseed
on 14 Mar 2017
Yes, this is mostly known. We know that there's some work to be done, not only for TypedArrays.

I had to abort buffer-swap.js benchmark after 2 runs because 1 run lasts ~ 2.5 hours, so default 60 runs would take 6 days. Maybe somebody with a free fast machine will be able to run a whole buffer-swap.js cycle later.

@vsemozhetbyt You can reduce the iteration count n (and/or the number of runs if the results don't seem to vary too wildly) if a single run takes too long. I would make sure a single run executes for at least 5-10 seconds or so to give V8 plenty of time to properly optimize code and whatnot.

@mscdex If I get it right, the problem is that a nominal 'one run', as the progress bar and the compare.js have it, includes many real runs with different config variants, from 2 up to more than 100. These real runs can last a very different amount of time with the same n parameter, from a second up to several minutes. If we try to keep all these real runs near at least 5-10 seconds, the real runs with maximum time span get a huge time span.
For example, I've reduced n for buffer-swap.js from 5e7 to 1e6. The whole set of 60 nominal runs has lasted ~ 3 hours, with one nominal run ~ 3 min. This benchmark has 66 config variants, some of them have lasted near 1 second, some of them have lasted near 15-20 seconds. To balance these cases, the n should be changed separately and conditionally for each config variant. Unfortunately, this can be achieved either by editing the code or by many complicated CLI arguments sets and separate runs.

@vsemozhetbyt Yep, benchmarking isn't always easy :-) Explicitly passing a lower --runs value may help as previously noted, especially for benchmarks that don't involve I/O and thus are usually less volatile.

hmm.. the streams results are interesting because I've been noticing a significant dip in streams performance in master compared to v7 and v6 in general without switching over to --ignition. I'd be curious to know if others have seen the same.
(that dip is really the only thing keeping me from landing the crypto module refactor I had done)

@bmeurer One of the tests deoptimizes with TurboFan for a not obvious reason.
According to the log, the problem is located at the ++i on line 29: https://github.com/nodejs/node/blob/master/benchmark/arrays/var-int.js#L29
This does not happen with Crankshaft.

@targos That looks weird, given that the relevant line https://github.com/nodejs/node/blob/master/benchmark/arrays/var-int.js#L29 doesn't have any named access. But I also doubt that this deopt is important, it's just a SOFT deopt, so next time main is executed it will be optimized with feedback.

The improvements on the ES6 features is not unexpected. I suspect that the performance losses we see in other areas could be made up for by taking advantage of the highly optimized new features. In particular, using defaults and rest params will provide a significant boost throughout core based on these results.

@jasnell Yes. Plus I noticed that some parts of Node core are sort-of written in _CrankshaftScript_, i.e. carefully tuned towards stuff that works extremely well in Crankshaft. Once I+TF is in for sure, we should revisit Node core and do some auditing/refactoring.

I'm trying to analyze the profile of buffers/buffer-bytelength:
- tf: buffers/buffer-bytelength.js n=100000000 len=1 encoding="utf8": 19,619,972.642906845
- cs: buffers/buffer-bytelength.js n=100000000 len=1 encoding="utf8": 33,020,356.335780904
It seems that TF spends a lot more time (and ticks) in C++ (70% vs 46%).
Full results: https://gist.github.com/targos/7f22961a9d930f867c563b1b2ffe6e1b

@targos Looks a bit like TF doesn't handle an API call in the fast case. That should be mostly the same logic in both TF and CS, but maybe we missed some corner case?

When would we expect to have this land? Seems like being prepared with some refactoring of core libs and internals would go a long way

FWIW: Here are 3 suites performed previously by @targos (on *nix?) here, here, and here — and now performed on Windows as the other suites. vm suite has most notable differences due to different n arguments (200000 vs default 1).

I would also be interesting to run the nightly benchmarks (at least acme air) on node with the newer level. I'll see if I can fit that in in the next few days.
mhdawson
on 29 Mar 2017
@mhdawson you can use the canary branch. I try to keep it regularly in sync with master and V8's lkgr.
targos
on 29 Mar 2017
@targos, that was what I was planning :)
mhdawson
on 30 Mar 2017
Can these benchmarks be rerun against the new LKGR branch? I believe these were last run against 5.7 which has a fairly difference perf profile
MylesBorins
on 12 Apr 2017
@MylesBorins They were run 5.9 against 5.9: before and after the commit that turned TF+I on. But yes, many things may change over the last month.

Maybe it would be better if somebody reruns them on a POSIX OS for a larger coverage / sampling.

Here is `arrays assert child_process crypto dgram domain` and some `es`.

I've selected node 6 vs node 8 cause this is probably what most people would migrate from.

Maybe someone can suggest a number of iterations so that all benches can run in ~8h ?
I know net ones can be fuzzy and buffer just takes way too long.

Is there an easy way to turn off and use the older v8 compiler? I am trying to test this in my server setup and i would like to run some tests with acmeair benchmark. I am not quite sure of how I can get an earlier branch of v8/node/vee-eight-lkgr before the commit.

You can pass --no-turbo. Or you could check out this commit.

Today the Node.js canary branch have been updated up to v8 6.0.
I've built it on Windows and run this simple benchmark script with a real life case, comparing canary and nightly:
'use strict';
const execSync = require('child_process').execSync;
const command =
'eslint --rulesdir tools/eslint-rules/ --ext=.js,.md benchmark doc lib test tools';
console.time('eslint1');
try { execSync(command, { encoding: 'utf8' }); }
catch (err) { console.error(err.stdout); }
console.timeEnd('eslint1');
console.time('eslint2');
try { execSync(command, { encoding: 'utf8' }); }
catch (err) { console.error(err.stdout); }
console.timeEnd('eslint2');
console.time('eslint3');
try { execSync(command, { encoding: 'utf8' }); }
catch (err) { console.error(err.stdout); }
console.timeEnd('eslint3');
// [email protected] + [email protected]
// node 8.0.0-nightly20170424 v8 5.7.492.69
eslint1: 47581.916ms
eslint2: 47971.909ms
eslint3: 46417.274ms
// node 8.0.0-pre v8 6.0.61
eslint1: 43372.365ms
eslint2: 42905.277ms
eslint3: 42554.953ms
This is a significant progress since almost the same v8 5.9 test (the eslint versions are different + doc linting is added, but I think this hardly distorts the comparison).

Nightly benchmark run on latest canary: https://ci.nodejs.org/view/Node.js%20benchmark/job/benchmark-footprint-canary/1/console. Will try to pull out comparison summary against master tomorrow.

Summary comparison between master and canary for nightly benchmarks. Note: just a single run of each so need more runs to validate:

Could we get an update on these stats based on the current 6.0 branch cut?
MylesBorins

@MylesBorins could you point to the 6.0 branch cut you are referring to .. ?
sathvikl
on 21 Jun 2017
I think @MylesBorins is talking about the nightly v8-canary build (which is node master + V8 lkgr), and available here: https://nodejs.org/download/v8-canary/

FWIW, v8-canary has V8 6.1 now.

If someone wants to build and test Node with V8 6.0, I have this branch: https://github.com/targos/node/tree/v8-6.0
targos
on 23 Jun 2017
should this stay open?
targos
on 20 Aug 2017
@targos I think we can close it now. If anybody objects, feel free to reopen.

@jasnell Yes. Plus I noticed that some parts of Node core are sort-of written in _CrankshaftScript_, i.e. carefully tuned towards stuff that works extremely well in Crankshaft. Once I+TF is in for sure, we should revisit Node core and do some auditing/refactoring.
