Performance benchmarks for daslang (formerly daScript).
This repository contains cross-language benchmark suites comparing daslang against Lua, LuaJIT, Luau, JavaScript (QuickJS), Quirrel, C#, and Zig.
Per-platform captures. A cell is the median of five samples, each its own process; a sample runs the kernel as many times as fit a 0.5 s budget and reports the per-run time, and ± is half the sample range as a share of the median. Lower is better. The fastest result in each row is in bold. - means no value for that runtime on that benchmark. The Startup table is hello world in every language on the boards: the wall time of one launch the way that lane's kernels are launched (median of ten after a warm one), and the size of the artifact the lane runs where it built one - a das exe links the daslang runtime library dynamically, a zig exe is static.
