I have had a quick look at the url you mentioned using Squid 3.0STABLE19 and IE7 (Windows XP SP2). There are 2 requests in the Squid access log which seem to take a while to retrieve: www.realestate.com/css/global/site.css followed by www.realestate.com/JS/common/re-all/re-all.js. These requests are approx. 200KB and 740KB respectively and take about 24sec and 42sec respectively to load on our ADSL2+ connection. When accessing the site directly rather than via squid from the same client, it takes about 15-20sec for the page to load. On the second access using Squid, the page loads in approx. 15-20sec. TCP_HIT is recorded in the Squid access log for the 2 urls mentioned above. I am not sure why it takes longer to load in Squid the first time except that maybe it is related to the browser using HTTP1.1 features (Accept-Encoding, Transfer-Encoding, etc) as I notice the data is compressed for the direct connection and uncompressed for the squid connection and the amount of data for the requests is approx 1/4-1/3 for the direct connection versus via squid. Perhaps Amos will have some ideas?
