Summary

Can't say I've focused to heavily on build time performances but since Zach Leatherman of 11ty put together a bench mark blog post and repo of some of the top SSGs, and so I figured I would test Greenwood just at least get a sense of where it sat amongst the rest.

I made a fork and decided to add Greenwood. 😬 🤞

I tried it on two machines and both had varying struggles:

  • MBP 2016 (Intel) - Interestingly enough, was mostly able to sustain builds through the 1000 -> 2000 -> 4000 range, albeit it took a while 🐢 😁 . But still had some issues here and there. I was able to get a 4000 page run on Node 14, fwiw
  • MBA 2020 (M1) - Had some OOO memory issues sometimes when doing 50 / 100 pages intermittently 😞
    % sh ./bench-greenwood.sh 100
    [bench] Clean complete
    [bench] Setup complete 100 pages

Here are specs, using the same approach Zach took. He didn't mention Node version, so for mine I used 16.14.0. The metric to track is real.

Each run was repeated 3 times and the lowest/fastest time was selected. This result set was generated on a MacBook Air (M1, 2020), macOS Monterey 12.5 12.3, 16 8 GB memory.

Details

So yeah, definitely some work we could / should do here, at least to chip away it for 1.0. Aside from the issues with the M1 chip one area of opportunity for sure seems to be the bundling phase as each benchmark run always seems to hang a little bit on this part of the process

success, done generating all pages...

Anyway, not sure what is realistic but would certainly like to be somewhat "competitive", as for v1.

Thoughts / Next Steps

  1. Confirm I am not running Node via Rosetta (for M1) - https://stackoverflow.com/a/65449002/417806
  2. Could be due to Worker threads, try with prerender: false - introduce worker thread pools for SSR page generation #983
  3. Bisect lifecycles (e.g. no bundle step) and see if that makes a difference. I know we do a lot of duplicate work in the bundle lifecycle which would be good to refactor out anyway. - refactor bundling lifecycle and resource optimizations #971
  4. Stamp out unique page templates only once, re-use between page renders
  5. Throttle max pages to build at once? Or just have it be a Promise.all free for all? - introduce worker thread pools for SSR page generation #983
  6. Out of even more curiosity, I wonder would it would look like to benchmark the 0.25.0 version, to see how the results would have come out if using Puppeteer. 😅
  7. Between prerender and bundle lifecycles, could we reduce "walks" over compilation.graph when iterating over pages. Maybe a Map / Set would be better here? - refactor bundling lifecycle and resource optimizations #971
  8. Benchmarking in CI (new issue)
  9. Actually run a profiler
  10. Maybe this would help (or hurt)? - make Greenwood CLI and plugins async through and through #823
  11. Does multiplying / increasing number of workers in the poll hurt or help?
  12. So... got cache busting to work for ESM, wonder if maybe we don't need to use Worker Threads anymore? (At least for production builds - Enhancement/issue 1088 refactor Workers out of SSR builds #1110)
  13. After removing Worker threads for Enhancement/issue 1088 refactor Workers out of SSR builds #1110, wonder if we can do this as well for thread pooling? Or would we still want Workers in some capacity?

So after applying the changes to from #983 , I was able to confirm now that we have no problems at least building 4000 pages without crashing now! 🙌

To help with comparisons, I will be focusing on the MBA benchmark for 4000 pages (user seems like the real world metric)

# 8 threads (os.cpus().length)
real	3m18.260s
user	3m24.175s
sys	0m27.565s
[bench] Build complete 4000 pages
[bench] Framework version

# 80 thread (os.cpus().length * 10)
real	3m21.573s
user	3m29.311s
sys	0m31.081s
[bench] Build complete 4000 pages
[bench] Framework version

# 160 thread (os.cpus().length * 20)
# it crashed hah 😅

Would probably good to actually do some performance profiling using the NodeJS inspector. Could be good as a follow up PR.
