Just do: ./shell -e 'var s = Date.now(); var i=1e7; while(i--); print(Date.now() - s);' ./jsc -e 'var s = Date.now(); var i=1e7; while(i--); print(Date.now() - s);'
This way we will see the cost of setting up/tearing down VM vs. the cost of running loop. (also ensure that your node/shell is compiled with snapshots (snapshot=on) so at least Context boostrapping time is not included). Then if you still can repro: specify all details of your build (OS, architecture, hardware vs. virtualized env etc). Also ensure that shell and jsc are of the same arch (file shell, file jsc). -- Vyacheslav Egorov On Sat, May 26, 2012 at 6:01 PM, Oliver Leics <[email protected]> wrote: > On Sat, May 26, 2012 at 5:26 PM, Bert Belder <[email protected]> wrote: >> On May 25, 11:21 pm, Oliver Leics <[email protected]> wrote: >>> On Fri, May 25, 2012 at 9:50 PM, Jorge <[email protected]> wrote: >>> > It does not take 3 seconds to start it up. >>> >>> Please explain: >>> >>> $ time node -e 'i=1e7; while(i--);' >>> >> >> Startup time should be in the order of 10s of milliseconds, so that's >> not it.
