Hi there:

   I am confused about these two statistics. Below is my console log:

   Could you please tell me what's the relationship between req_rate
and reply rate? I find that they are rather different from each other.
(The reply rate is much lower than req_rate)

   The response time is rather high . I wonder if I can trust the
resulting response time I get.

   Maybe the squid server don't has so much tolerance? (for req_rate
higher than 100)
  

   Thank you very much..:)
