Re: [Pharo-dev] Simple benchmark RBParser vs. Shout

Hi,

I want to get a feeling of how much faster Shout is compared to RBParser. This is a very simplistic bench:

[Morph methods do: [:method | RBParser parseFaultyMethod: method sourceCode ]] bench. "'3.197 per second'"

[Morph methods do: [ :method | SHTextStylerST80 new rangesIn: method sourceCode setWorkspace: false.]] bench

"'2.797 per second’"

This means that parsing performance alone is actually not bad with RB… (it would be interesting to look at edge cases…)

And then of course the next thing to do is the highlighting itself.

With highlighting AST vs. Shout, Shout is a bit faster: [Morph methods do: [:method | SHTextStylerST80 new classOrMetaClass: method methodClass; styledTextFor: method sourceCode asText]] bench. "'2.301 per second'" [Morph methods do: [:method | SHRBTextStyler new classOrMetaClass: method methodClass; styledTextFor: method sourceCode asText]] bench "'1.935 per second'" Marcus
