Question

我制作了一个小的python脚本来对我上传之前一直在努力的网站进行压力测试。它通过每隔5分钟产生一个新线程来运行，该线程在一段时间（真实）循环中运行下面的代码。

conn = httplib.HTTPSConnection("site", 000, "pem", "pem", timeout = 30)
conn.request("GET", "/reports.php?" + url, headers = headers)
response = conn.getresponse()
read = (response.read())

如果我只有一个线程，则代码请求/响应每次都成功。当我创建新线程时，我会更频繁地得到以下错误。最终当有大约10个线程时，它会在90％的时间内失败。

  File "/usr/lib/python2.7/ssl.py", line 151, in read
    return self._sslobj.read(len)
SSLError: The read operation timed out

我想知道ssl代码httplib使用的是不是线程安全的还是有其他原因导致失败？

它是线程安全的。您可能想要开始研究服务器代码的性能......
