heh, I've worked for companies that hit the max on cookie size (which I think is around 60kb). For an entire framework to be 60kb would be amazing for these companies :)

Wow - 60kb for cookies is crazy.

Where's the benchmark showing this?

https://stefankrause.net/js-frameworks-benchmark8/table.html - thats old lit release there vs react 16 (react pre 16 would be slower and everyone agrees its generally fast already), on slack channel I believe I saw newer release benchmarks that are better (it also depends at which specific test you look at).

New version of repeat is interesting:

I compared my usual candidates: vue, inferno, Surplus and vanillajs, and lit-html was dead last overall in almost every category. Also slower than Preact now that I checked, so I'm not sure that performance benefits are one of lit-html's unique strengths.

Yup, notice that from the slack screenshot that I posted it has speed mark 1.18 that puts it before Vue in terms of speed (which makes it plenty fast IMO, and its not even stable yet), I never claimed it is the fastest one of the bunch.

Nicoburns said that "performance question is not solved" - I think we can agree than svelte and lit are fast in general, that was the point I wanted to make that it is the implementation that matters here.

There you go, https://rawgit.com/krausest/js-framework-benchmark/master/we..., much faster than vue and react (still not inferno speed yet, but the gap is closing).

Not bad. I'm always amazed at Surplus though, that's the one to beat!
