fs: improve fsPromises readFile performance #37608

Linkgoron · 2021-03-05T11:33:48Z

Improve the fsPromises readFile performance by allocating only one buffer, when size is known. I also increased the size of the readbuffer chunks (which are now the same as in read_file_context), and also removed the extra read if size bytes have been read.

Most of the changes here are essentially shamelessly copied from read_file_context, I've also removed a call to the inner read and just called binding.read directly.

I also had to fix a few abort-controller tests, as they were dependant on the extra read at the end of the file.

This improves the promises.readFile performance by 20% on my machine. However there is still a 15-20% difference between the cb version and this version on my machine, so I didn't mark this as resolving #37583

edit:
second commit contains fs.promises.readFile benchmark

I went all the way back to https://github.com/nodejs/node/pull/18297/files to see if there is a compelling reason that buffer size was chosen - looks like it was tried initially and not really iterated on - so this change looks fine :)

@benjamingr I believe that the number was changed in read_file_context here #27063, but probably missed changing it as an oversight in the promisifed version.

Personally I'm in favour of not spending mental energy on stylistic changes that are not enforced as part of linting rules.

I've copy-pasted the readfile benchmark and converted it to a promisified version and these are the results of the comparison tool:

lib/internal/fs/promises.js

+      buffer = fullBuffer;
+      offset = totalRead;
+      length = MathMin(size - totalRead, kReadFileBufferLength);
+    }


Note that this is a behavioral change for files that are being appended to while they are being read. I think that should be okay, because ultimately there are no guarantees for the relative timing of the two operations, but it might be something to keep in mind.

Yes, you're correct and I should've mentioned it in the PR but forgot. This is aligning the behaviour with the cb version, so I thought that it would be OK.

node/lib/internal/fs/read_file_context.js

Line 110 in 26288ff

length = MathMin(kReadFileBufferLength, this.size - this.pos);

Yeah, I think that’s okay 👍

lib/internal/fs/promises.js

-    const buf = Buffer.alloc(isFirstChunk ? firstChunkSize : chunkSize);
-    const { bytesRead, buffer } =
-      await read(filehandle, buf, 0, buf.length, -1);
-    endOfFile = bytesRead === 0;


nit: it looks like it should be enough to change this line to:

totalRead += bytesRead; endOfFile = bytesRead === 0 || totalRead === size;

in order to get the same performance improvement as in this PR (at least that's what I saw on my machine). Another useful optimization here is Buffer.allocUnsafeSlow. So, maybe it's worth considering keeping only these 4 lines of changes, but with the same result.

I agree that some of the changes are not strictly necessary for the improvement, but another feature (IMO) of my changes it that now the logic is essentially the same as the sync readFile.
