How many external FastCGI children are you running? On the first request each child processes, it needs time to minify the JS and CSS assets. Every request after the first for a child process will be much much quicker. If you have a lot of children, you may need to hit the RT server at least that many times until you get a child that already processed the JS and CSS. In a normal production system, this isn't a problem. > some_ip - - [27/Jun/2011:13:18:48 +0200] "GET / HTTP/1.1" 200 1778 "-" > "Mozilla/5.0 (X11; Linux i686 on x86_64; rv:6.0a2) Gecko/20110620 > Firefox/6.0a2" 3.451s > some_ip - - [27/Jun/2011:13:29:19 +0200] "GET / HTTP/1.1" 200 4032 "-" > "Mozilla/5.0 (X11; Linux i686 on x86_64; rv:6.0a2) Gecko/20110620 > Firefox/6.0a2" 2.900s > some_ip - - [27/Jun/2011:13:29:45 +0200] "GET / HTTP/1.1" 200 4030 > "http://rt.depesz.com/Ticket/Display.html?id=1517"; "Mozilla/5.0 (X11; Linux > i686 on x86_64; rv:6.0a2) Gecko/20110620 Firefox/6.0a2" 3.549s > some_ip - - [27/Jun/2011:13:33:10 +0200] "GET / HTTP/1.1" 200 4088 > "http://rt.depesz.com/Ticket/Display.html?id=17472"; "Mozilla/5.0 (X11; Linux > i686 on x86_64; rv:6.0a2) Gecko/20110620 Firefox/6.0a2" 6.539s > some_ip - - [27/Jun/2011:13:34:30 +0200] "GET / HTTP/1.1" 200 4032 > "http://rt.depesz.com/"; "Mozilla/5.0 (X11; Linux i686 on x86_64; rv:6.0a2) > Gecko/20110620 Firefox/6.0a2" 0.275s See the line above? It's super quick. I bet you hit a FastCGI child which had already minified the JS and CSS.
