The dasProfile suite runs the same programs across daslang and the scripting
runtimes it competes with — Lua, LuaJIT, Luau, Quirrel, QuickJS, Mono and .NET —
plus C++ as the floor. Two boards per platform: pure interpreters, and
everything with a JIT or AOT compiler behind it. Absolute seconds, lower is
plus C++ and Zig as the native floor. Three boards per platform: pure interpreters,
everything with a JIT or AOT compiler behind it, and startup - the wall time of one
launch of each program as a script, under the JIT, and as a standalone exe. Absolute seconds, lower is
better; the fastest lane in each row is highlighted.
