javascript - node.js process.hrtime in asynchronous server? -

-

i create http server using http.createserver(onrequest) , want measure time needed make response.

currently, in onrequest handler do:

var start = process.hrtime();  response.on('end', function (){     console.log('time respond', process.hrtime(start)); });  // call various asynchronous functions , send them 'response' object. 1 of them response.end()

i'm worried if work fine when bunch of requests comes instantly, or asynchronism break it/mix-up times?

the variable in closure scope of onrequest handler function it'll work way expect (assuming process.hrtime want).

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
