Ignition + TurboFan: Node.js benchmarks #11851

Closed vsemozhetbyt closed 7 years ago

vsemozhetbyt commented 7 years ago

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.

hashseed commented 7 years ago

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

Fishrock123 commented 7 years ago

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

hashseed commented 7 years ago

@bmeurer @psmarshall could we keep an eye on this?

bmeurer commented 7 years ago

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.

A gist with the same data.

@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.

TOC added to the first post to find results more quickly (will be updated).

@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.

jasnell commented 7 years ago

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.

bmeurer commented 7 years ago

@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.

@bmeurer Maybe the reported reason is wrong. It's true that main would be optimized again, but it is run only once. I rewrote the benchmark differently and now the results are much better and without deopt:

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).
