No, you can't do the same thing in Rust, because Rust crates and the standard library generally use the global allocator and not any arena you want to use in your code.

The paper does not make that claim. According to the paper the probability of recovering the correct value of a single bit is 96% for a pristine drive and 56% for a used drive, both better than a coin toss. Of course the probability gets wo

WSL2, correct.

Yep, see below. With WSL and an ext4 virtual disk it takes only 29 seconds. Still quite a bit more than the 22 seconds on the Macbook.

cargo install on WSL2 uses the non-mapped home directory, which is on an ext4 virtual disk. That is probably one reason why it is six seconds faster.

Nope, pure compile time on a Core i7-10750H with Windows and Rust 1.52.1, antivirus disabled. WSL did not make much of a difference though (29 seconds).

It does not just feel faster, in many cases it is faster. E.g. compiling Rust code is so much faster that it is not even funny. cargo install -f ripgrep takes 22 seconds on a Mac Book Air with M1, same on a hexacore 2020 Dell XPS 17 wit

As far as I can see it does not use SIMD for UTF8 validation, only likely/unlikely instrinsics, see https://github.com/hsivonen/encoding_rs/blob/e98a2096ab09c92...

Check the benchmarks section ( https://github.com/rusticstuff/simdutf8#Benchmarks ), second table. simdutf8 is up to 28 % faster on my Comet Lake CPU. However with pure ASCII clang does something magical with simdjson an

How is the performance compared with simdjson ( https://github.com/simdjson/simdjson )?

by kryps 6y ago
Tip: Rust BufReaders default to 8KiB buffers which are way too small for high-performance sequential NVME I/O.

Not sure about the speed compared to Genymotion. HAXM is still required but less buggy now.

Make sure to fix the zippers in place. Otherwise it is very easy to still open the bag by just prying open the zippers and closing them again by moving the tied-together zippers. https://www.youtube.com/watch?v=G5mvvZl6pLI

For critbit trees the entire string _up to_ the critical bit where the string differs from all others already in the datastructure needs to be scanned. critbit trees degenerate badly if you store strings and their prefixes, e.g. storing a,
