multithreading - Making massive numbers of HTTP requests in Python -

-

i'm trying test web application, part of involves making ~10k requests, taking few <1k return 200 ok , going through data. webapp buggy , there false positives, each 200 ok needs @ least triple-checked.

working in python trying threading , urllib, on linux thread errors after ~920 threads. (my theory it's /proc/sys/kernel/threads-max divided thirty eerily accurate, it's perturbing each thread register 30 threads os). in case, i'm looking solution task. i've looked twisted, seems still bound threading.

any ideas?

i testing whit apache ab web server tornado , unable go on 1000 connections per second on dual core athlon @ 2ghz . 30% resources took testing tool ab , remaining server. pretty convinced resources spent os , ip-eth layer.

non blocking servers have better performance blocking servers since not spawn tread each connection. in theory can run in single tread.

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,
