Somewhere between 0 and infinity. We do not measure HTTP agents in terms of "users" because one single user can flood a network, or many tens of thousands per second be handled easily. It depends entirely on what type of message any given user is sending at any particular moment. So HTTP is measured best in request-per-second (RPS). For most HTTP/1.1 traffic Squid can handle around 10-20K requests per second before performance tuning needs to happen, after tuning twice that. > 2) How many "acl bypass_parent" URLs can my cache squid proxy server > handle before browsing starts to slow? What is being done with these URLs? Simply having them configured does not affect browsing. Testing the same few values repeatedly likewise is not noticable for the better ACL types. Using something like a regex ACL or testing random URLs from the set without any pattern to tune for all result in quite low numbers before traffic slows.
