Allocation Performance

Description

Measured allocation performance using following code with n=10:

class A:
    pass

def alloc(n):
    for i in range(n):
        a = A()

def target(driver, args):
    ...
    def main(argv):
        ...
        for i in range(iterations):
            cb.begin()
            for j in range(1000000):
                alloc(n)
            cb.end()
        cb.report(resfile)
        return 0
