While getting an iconv decoder isn't particularly slow, I noticed it happens a lot when decoding lots of varchar rows. From internal testing, with 5000 rows of a table containing two varchar utf8mb3 columns (length 100 and 500), I'm seeing about 12% speedup with this change.

if (Buffer.isEncoding(encoding)) {
return buffer.toString(encoding, start, end);
}

const decoder = Iconv.getDecoder(encoding, options || {});
// Optimize for common case: encoding="short_string", options=undefined.

I figure encoding is probably constant for most users. For my use case, it's always "cesu8" (for utf8mb3).

It looks like the CI failures are a few timeouts waiting for MySQL to come up. Unrelated to changes.

Hi @sandinmyjoints, about the CI - OSX, please ignore them for now 🙋🏻‍♂️

I run the "re-run" from time to time until the tests runs to its end.

lgtm, thanks @sandinmyjoints !

A suggestion would be to require LRU as const LRU = require('lru-cache').default to improve the compatibility with Next/Nuxt, etc.

What do you think, @sandinmyjoints? 🙋🏻‍♂️
