+# Using SIMD for libc
+
+I found that implementing some libc functions with Wasm SIMD128 can make them significantly faster.
+
+Rough numbers for [wazero](https://wazero.io/):
+
+  function   | speedup
+------------ | -----
+`strlen`     |  4.1×
+`memchr`     |  4.1×
+`strchr`     |  4.0×
+`strrchr`    |  9.1×
+`memcmp`     | 13.0×
+`strcmp`     | 10.4×
+`strncmp`    | 15.7×
+`strcasecmp` |  8.8×
+`strncasecmp`|  8.6×
+`strspn`     |  9.9×
+`strcspn`    |  9.0×
+`memmem`     |  2.2×
+`strstr`     |  5.5×
+`strcasestr` | 25.2×
+
+For functions where musl uses SWAR on a 4-byte `size_t`,
+the improvement is around 4×.
+This is very close to the expected theoretical improvement,
+as we're processing 4× the bytes per cycle (16 _vs._ 4).
+
+For other functions where there's no algorithmic change,
+the improvement is around 8×.
+These functions are harder to optimize
+(which is why musl doesn't bother with SWAR),
+so getting an 8× improvement from processing 16× bytes seems decent.
+
+String search is harder to compare, since there are algorithmic changes,
+and different needles produce very different numbers.
+We use [Quick Search](https://igm.univ-mlv.fr/~lecroq/string/node19.html) for `memmem`,
+and a [Rabin–Karp](https://igm.univ-mlv.fr/~lecroq/string/node5.html) for `strstr` and `strcasestr`;
+musl uses [Two Way](https://igm.univ-mlv.fr/~lecroq/string/node26.html) for `memmem` and `strstr`,
+and [brute force](https://igm.univ-mlv.fr/~lecroq/string/node3.html) for `strcasestr`.
+Unlike Two-Way, both replacements can go quadratic for long, periodic needles.
