To be more elaborate, i am trying to use v8 on windows woth C++ application. When i initialize my application, i compile the script. The compile script is stored along with the context in which it is compiled. So i have code as follows: v8::Persistent <v8::Context> context = v8::Context::New( NULL, context);
v8::Handle <v8::String> source = v8::String::New ( "my script"); v8::Handle <v8::Script> compiledSource = v8::Script::Compile( source ); v8::Persistent <v8::Script > scriptHandle = v8::Persistent<v8::Script>::New(compiledSource ); I cache the scriptHandle, and context (Persisten handle) in my application. Later in another funtion i try to Run the script as follows: { v8::Locker l( isolate ); v8::Isolate::Scope iscope( isolate ); v8::HandleScope handle_scope; for(int i = 0; i < 1; i++) { //pV8Item is the object (cache) where is store the persistent handle of context and compiled script ( pV8Item->contextOrder )->Enter(); ( pV8Item->objOrder )->SetInternalField( 0, v8::External::New(order) ); ( pV8Item->sRulepCompExp )->Run(); } } I have to run the above function 100,000 times. There is a performance hit here. The function takes a long time to execute. Any help on this?
