javascript - Reference material for calculating response times -

-

i have mobile application (ios) sends instructions via comet server (ape) web application (js). each instruction, web application responds "ack" message, tagged instruction id. want calculate average response time web application.

the frequency of instructions may vary 5 per second on every other second (or longer, depending on user).

my naive solution timestamp each send , receive , calculate average among differences. inefficient since algorithm (basic for-loop) stalls application , inflicts delay in handling acks. solution use ten latest timestamps , limiting number of response times calculation.

i'm not happy solution , looking reference material provide me information problem i'm facing.

here use, not based on scientific material, works me...

we keep average of last 10 + keep worst 2 ever , best 2 ever. don't persist data, worst/best 'ever' measured since reboot of application server.

then make average on these 14.

hope helps.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,
