这几句说不太清楚,容易引起误会,还是直接贴代码吧

def run_download_test(self, mirrors=None, max=None, borders=(0,1),
                          mod=(0,0)):
        """Performs download tests of the given mirrors and returns the
           best results (specified by max).
           Mod and borders could be used to tweak the reported result if
           the download test is only a part of a whole series of tests."""
        def test_download_speed(mirror):
            url = "%s/%s" % (mirror.get_repo_urls()[0],

"pool/main/f/firefox/firefox-dbg_3.6.13+build3+nobinonly-0ubuntu0.10.10.1_i386.deb")
