"LLRT offers up to over 10x faster startup"
is this what low latency means?
im curious if there are other benefits.x2 lower costs are also pretty big if true!
Yeah it's built on the quickJS runtime that has a low footprint and fast startup but no JIT, so in anything longer than the v8 startup, it ends up being about a magnitude slower

https://github.com/awslabs/llrt/raw/main/benchmarks/node20-ddb-put.pngMaybe I'm just stupid, but what are these numbers?
"HTTP benchmarks measured in round trip time for a cold start"
Soo, I'm guessing it's round trip time in milliseconds?
What is p0 to p100? Are they putting 0 to a 100 items? Are they putting 1 item into a dataset of size p..?
Percentiles of the measured startup times.
p100: 100% of the startups were slower, this is the maximum time they measured.
p50: 50% were slower than this
And so on to p0, which is the smallest measured time.
