Benchmarks

Seemingly every JS lib on Earth claims to have Blazing or Lightning Fast performance.

Fortunately, we don't have to rely on bench-marketing or 2017-era proclamations. "Trust, but verify" ;)

Hardware CPU: Ryzen 7 PRO 5850U (1.9GHz, 7nm, 15W TDP)
RAM: 48GB

NodeJS v20.6.0

Synthetic Datasets

The goal of this section is to give all parsers some simple synthetic datasets as a "peak performance" litmus test -- one without malformed data or delimiters within quotes. Parsing here is from CSV strings loaded into memory (no file streaming) and the output is string values, avoiding any additional overhead of conversion to numbers, booleans, dates, etc. While the usefulness of to-string parsing is limited to rendering rather than data processing, every token starts life as a string, so this is a good baseline.

We won't waste time on small datasets -- they're uninteresting. To create meaningful GC/memory pressure, but without hitting Node's default 2GB limit, we'll create three files with 20 columns x 10,000 rows.

Notes:

  • Bizzarely, the throughput of many parsers (including String.split()!) drops off a cliff with integer strings, even though we're not actually converting anything to integers, the memory usage is unchanged, and the dataset is 50% smaller.
  • A significant portion exhibits 40%-60% performance deterioration when quotes are introduced.
  • Despite enabling .supportQuotedField(true), CSVtoJSON does not properly remove the wrapping quotes from column names.
  • Some libs require non-default settings here to extract the most performance (e.g. omit value typing, output tuples instead of objects)
  • json-2-csv is so irredeemably slow that it will be excluded from additional benchmarks to save my CPU from a premature meltdown.

Dekkai and SheetJS

Before moving on we need to talk about Dekkai and SheetJS.

These two libs have "native" formats that they parse to, and expose additional APIs to convert this format to plain JS arrays of records (as tuples or objects), which is the native format of all other libs. These APIs are used by benchmark in order to compare apples to apples, but this imposes some performace cost which we'll dissect here.

SheetJS is pretty straightforward with a predictable impact due to having a JS-native format that is directly convertible via XLSX.utils.sheet_to_json(sheet);:

If you are using SheetJS to load CSV files and continue to use its API to access the parsed data (instead of native JS methods), then this slowdown may not affect you.

The situation with Dekkai is a more nuanced than its own benchmarks would have you believe.

How Dekkai works is by parsing chunks of data in worker thread(s) using WASM. What I assume it does is simply stores arrays of offsets where it found row and column delimiters in each chunk. By itself, this process can be quite fast.

// native
let table = await dekkai.tableFromLocalFile(file);

So, what's the catch?

Well, when you actually need to touch the data, you pay a lot for that privilege.

// native + row-access
let table = await dekkai.tableFromLocalFile(file);

await table.forEach(row => {
  // do nothing
});
// native + row-access + value-access
let table = await dekkai.tableFromLocalFile(file);

await table.forEach(row => {
  row.forEach(val => {
    // do nothing
  });
});

If we want to compare apples to apples, we have to look at the bottom Dekkai entry, where we incur the cost of decoding and allocating every parsed value into native JS types, as they are in all other parsers.

Dekkai's benchmark shows it being 5x faster than Papa Parse when streaming and summing a single integer column of a 3.6M row dataset, but I haven't found evidence of this either.

Anyways...the remainder of this benchmark will use the Dekkai and SheetJS code which produces the same output as the other parsers. If you'd like to poke around the other variants, they're available in this repo.


Real Datasets

Synthetic datsets can be too uniform to extrapolate actual performance in production environments. Testing with real data can surface inefficiencies in code paths that were either bypassed or infrequently executed.

Notes:

  • With this 36MB dataset, all the faster libs bump into the 2GB memory limit. With GC'd/JIT'ed runtimes, lower peak memory does not imply faster perf (as was the correlation in the synthetic runs).
  • uDSV is not faster by the same huge margin over PapaParse as in the synthetic litmus_ints.csv case where it was 251 MiB/s vs 74 MiB/s.

Typed Parsing

If you have numeric data, booleans, dates, or embedded JSON, you'll likely want to convert these from strings to native JS types.

Each parser does this differently:

  1. Some provide a setting for this natively
  2. Others expose a user-defined, per-value callback that leaves conversion to the user
  3. The rest expect you to convert the output yourself

Thing is, due to crappy built-in implementations, the fastest option is usually the last one...if you know what you're doing. Consequently, very few users will actually reap the full performance of #3; most will pick #1 or seek out libraries that offer it.

For example, here's the difference with PapaParse (untyped, natively-typed, manually-typed):

Option #3 (manually post-processed) integer conversion is more than 2x faster than using the official dynamicTyping: true (Option #1). This route is available to all libs, but performance fully depends on user competence. Since we're here to assess libs and not users, we'll only compare libs with some kind of type conversion API.

Notes:

  • uDSV offers the simplicity of Option #1 with the performance of Option #3.
  • I could not find typing options for these parsers: but-csv, @fast-csv/parse, jquery-csv, @gregoranders/csv, @stdlib/utils-dsv-base-parse.
  • ACsv.js and node-csvtojson provide typing only via static column config, so they're excluded for not being generic.

Notes:

  • The values in the Types column are important. All parsers that show object called JSON.parse() on the embedded JSON strings for each of 34K rows in this dataset. Additionally, there are 3 columns of boolean values here, so those without boolean did not do the work of converting 3 * 34k TRUE/FALSE strings.

Streaming

There are two categories for streaming: retained and non-retained.

Streaming that retains will keep all parsed output in memory while non-retained will discard the parsed data after running some reducer on each chunk, such as sum or filter.

Notes:

  • When using logically-similar code, I'm not able to get the extremely slow performance numbers they show for Papa Parse in their bench results.

Here's a run with our numeric litmus dataset, which shows similar results:

Output Formats

For libs that support different output formats (tuples, objects, columns, nested objects), there is often a performance penalty for when switching away from the default.

We're not going to look at every lib here, but switching PapaParse to object mode (header: true) looks like this:

Nested Objects

csv42 was written to improve on parsing and stringifying nested JSON structures to and from CSV: https://jsoneditoronline.org/indepth/parse/csv-parser-javascript/

While uDSV does not currently offer CSV generation, it does offer ~4.5x faster deep parsing to structured objects:
