Running ZSV lib from Javascript is still experimental and is not yet fully optimized.
48+
Some performance challenges rae particular to web assembly + Javascript, e.g. where a lot of string data
4949
is being passed between Javascript and the library (see e.g. https://hacks.mozilla.org/2019/08/webassembly-interface-types/).

Furthermore, it is unlikely that zsv-lib can approach its full performance potential
52-
until emscripten (or gcc) [can provide a SIMD-powered movemask function](https://github.com/WebAssembly/simd/pull/201). Until then, libzsv in emscripten resorts to the "slow"
53-
movemask, which does have a significant impact.
51+
However, initial results are promising:

Current testing suggests that on small files (under 1 MB), zsv-lib is 30-75% faster than, for example, the `csv-parser` library. However, on larger files,
56-
due to the aforementioned Javascript/wasm memory overhead and lack of
57-
SIMD movemask, it can be more than 50% slower than `csv-parser`.
53+
* Running only "count", zsv-lib is ~90%+ faster than `csv-parser` and `papaparse`
54+
* The more cell data that is fetched, the more this advantage diminishes due to the aforementioned Javascript/wasm memory overhead.
55+
Our benchmarking suggests that if the entire row's data is fetched, performance is about on par with both csv-parser and papaparse.
56+
If only a portion is fetched, performance is about the same for papaparse, and faster than csv-parser (how much faster
57+
being roughly proportional to the difference between count (~90% faster) and the
58+
amount of total data fetched)
