How a Rust upgrade more than tripled the speed of my code
I’d like to share a quick story about the sheer power of LLVM and the benefits of using higher-level languages over assembly. I work at Parity Technologies, who maintains the Parity Ethereum client. In this client we have a need for performant 256-bit arithmetic, which we have to emulate in software since no modern hardware supports it natively. For a long time we’ve maintained parallel implementa
Speeding Up `dwarfdump` With Rust
Robert O'Callahan. Christian. Repatriate Kiwi. Hacker. Writing a debugger for C++ on Linux, you spend a lot of time examining pretty-printed DWARF debug information using tools like readelf, objdump or dwarfdump. Unfortunately this can be quite slow. For Firefox's libxul.so, dwarfdump's pretty-printed output of just the main .debug_info is 25GiB. The standard objdump and readelf tools take about t
Rustで高速な標準出力 | κeenのHappy Hacκing Blog
κeenです。Rustで何も考えずに標準出力に吐いてると遅いよねーって話です。 今回、標準出力に「yes」と1000万回出力するアプリケーションを書いてみたいと思います。 println! まあ、最初に思いつくのはこれでしょうか。
A comparison of regex engines
Introduction Regular expressions (or just regex) are commonly used in pattern search algorithms. There are many different regex engines available with different support of expressions, performance constraints and language bindings. Based on the previous work of John Maddock (See his own regex comparison) and the sljit project (See their regex comparison) I want to give an overview of actively deve
Optimizing Rust Binaries: Observation of Musl versus Glibc and Jemalloc versus System Alloc
I'm just chiming in to report an observation with compiling Rust applications using both the glibc (default) and musl targets, as well as jemalloc versus system-alloc. In all the scenarios I've tried, musl-compiled Rust binaries are significantly faster than their glibc counterparts, so it's worth investigating this in your own projects. I've seen speedups ranging from 50% to 1000% faster. I manag
How to speed up the Rust compiler – Nicholas Nethercote
Notes on Rust, Firefox, MemShrink, JavaScript, and more Rust is a great language, and Mozilla plans to use it extensively in Firefox. However, the Rust compiler (rustc) is quite slow and compile times are a pain point for many Rust users. Recently I’ve been working on improving that. This post covers how I’ve done this, and should be of interest to anybody else who wants to help speed up the Rust
Optimising string processing in Rust
In this article, I'd like to explore how to process strings faster in Rust. I'll take the example of a function to escape the HTML <, > and & characters, starting from a naive implementation and trying to make it faster. Warning: I'm not an expert in this domain. While I do have a computer science background, I haven't had a job in this domain for nearly ten years, I am not an expert of Rust, and
