perf(rome_cli): replace global allocator with jemalloc #3237

ematipico · 2022-09-16T09:04:57Z

Summary

This PR replaces the default global allocator to use jemallocator on all operative systems, exception for Windows because it's not supported.

Test Plan

Here's some benchmarks from my machine (I use macOS)

Memory consumption

I used cargo instruments and I am not an expert at using the trace tool provided by XCode. I share here the screenshots and the trace file in case someone has more knowledge than me.

I run the formatter on the prettier repository, their src folder. No --write.

Playground for commit 7647d7b

MichaReiser · 2022-09-16T09:12:52Z

Have you compared performance with mimalloc? Depending on different allocators for every platform increases the risk of platforms specific issues and requires us to test every change on every platform.

That's why I would prefer to use the default system allocator for all (maybe except windows) platforms or replace the default for all platforms.

MichaReiser · 2022-09-16T09:17:25Z

You know... this will make it more difficult for me to prove that any of my work reducing allocation is any good :P

IWANABETHATGUY · 2022-09-16T09:20:27Z

Would you mind explaining why replacing an allocator will make it harder to prove reducing allocation ?

Forgive me this stupid question.

MichaReiser · 2022-09-16T09:21:34Z

Would you mind explaining why replacing an allocator will make it harder to prove reducing allocation ?

If every single allocations becomes cheaper than reducing the number of allocations has less effect on the overall performance.

@ematipico Would you mind also comparing the memory consumption? Do you have links that compare the different allocators?

Depending on different allocators for every platform increases the risk of platforms specific issues and requires us to test every change on every platform.

Technically we are already depending on different allocators for different platforms, since we use whatever allocator is provided by the OS. I don't know if mimalloc compares favorably to jemalloc in terms of performance, as always with perfs this is something we need to benchmark with our workloads to be sure. In any case I think it would be interesting to use jemalloc on all Unix systems instead of just macOS and mimalloc on Windows, this way we would still smooth out most platform discrepancies by using the same allocator (almost) everywhere

Also, what's the impact of this change on the size of the rome binary ?

What was your reasoning why you preferred minmalloc over jemalloc?

ematipico · 2022-09-16T10:18:25Z

The reason why I tried jemalloctor for macOS first was mainly because lighthingcss uses it (former ParcelCSS). And I gave it a try and see what's the result on our benches.

I will give it a whirl in terms of memory usages once I manage to download again all the necessary software. We can close it if you think it's not worth it.

leops · 2022-09-16T11:56:39Z

What was your reasoning why you preferred minmalloc over jemalloc?

For Windows the reason was simply that tikv-jemallocator doesn't support it

The results seem very promising! My main concern is that I want to avoid having one custom allocator for every platform that we support. Using minmalloc for windows and jemallc for UNIX systems seems a reasonable balance between performance and too many configurations (even though I haven't seen any significant improvements on linux)

ematipico · 2022-09-20T07:36:00Z

So, should we just switch to use this allocator for all the OS expect windows?

MichaReiser · 2022-09-20T11:32:22Z

So, should we just switch to use this allocator for all the OS expect windows?

Probably. But it would still be interesting to get some more numbers:

How does it change performance results on linux
Is there a way for us to compare memory consumption before/after? If so, what are the numbers

@rome/staff I updated the description of the issue with some findings around memory consumption.

MichaReiser

I'm not sure if the allocation numbers are representative because they're only measuring how much memory was requested and freed by the system allocator which is expected to be less if you use a custom allocator that re-uses allocations before requesting new pages from the system allocator.

However, you shared some numbers over slack which are promising.

I checked with activity monitory. With jemalloc the memory usage is around 20MB top. main instead is 45MB top

I think the results overall are very promising and I verified them on my local machine. There are a few cases where performance regresses or does not improve, but the numbers greatly improve for all benchmarks traversing the CST.

@leops and @xunilrj what do you think? The numbers seem good and so far I could not see any issue locally. Should we make the switch to jemalloc for all operative systems? (exception for windows)
