Hi, I set up a dev instance of squid on my windows system. I've configured 2 browsers (Chrome & Firefox), chrome direct to the internet, firefox through the locally running instance of squid. I expected similar response times from the two browsers, but I consistently see firefox (configured to proxy through squid) takes 4x+ longer. Below are the logs showing response times from a hit on yahoo.com, the chrome browser opened the page in ~<2 seconds. I have used the windows binaries of squid and configured digest password authentication, everything else (other than default port) is left as default in the config file. After doing a packet capture I noted the following behavior: - When going through the proxy: 9 GET requests are made, and 9 HTTP responses are received in a reasonable time period (<2sec) - After the 9th HTTP response is sent, there is a 4 second delay until the next GET request is made - Then 6 GET requests are made, and 6 HTTP responses are received in a reasonable amount of time. - After the 6th GET request in this second group there is a 5 second delay until the next GET request is made. - This pattern repeats its self when the proxy is in use. - This pattern does not occur when I am not connected through the proxy. Any thoughts on this behavior?
