Few weeks ago I got me a new laptop (battery circuitry of my old Asus UX305 got fried). This one is Asus UX410, with Intel i7-8550U processor and 16GB of DDR4 RAM.

To check performance, I use Rust JSON Benchmark:

git clone https://github.com/serde-rs/json-benchmark
cd json-benchmark
git rev-parse HEAD
rustc --version
cargo run --release --bin json-benchmark

Results:
