                start = time.time()
                func(*args,**kwargs)
                print func.__name__,'run:',time.time()-start
        return _wrapper

@func_time
def remove():
        posts = db.userinfo
        print 'count before remove:',posts.count();
        posts.remove({});
        print 'count after remove:',posts.count();

if __name__ == "__main__":
        remove()
