+1 A place for benchmarks is a great start. There's a few obvious things we'll want to measure (the bridge, file i/o) but I imagine other things will start coming to mind like initialization and resume/cleanup performance.
Created a JIRA issue for CordovaJS for it. https://issues.apache.org/jira/browse/CB-1528 On Sat, Sep 22, 2012 at 4:39 PM, Andrew Grieve <agri...@chromium.org> wrote: > I'd love to see this benchmark checked into mobile-spec. > > Probably we should create a sub-page for benchmarks, just like there is for > Automated Tests. > > > On Sat, Sep 22, 2012 at 10:20 AM, Simon MacDonald <simon.macdon...@gmail.com >> wrote: > >> Here's my two cents.
