This is my first time on your site. It is so useful! Thank you very much.
My site’s time-to-first-byte being served is an awful 12.4 secs for the first view and 8.3 secs for the repeat view. (http://www.webpagetest.org/result/110205_8Z_33X7/)
I am experimenting with combining and compressing files on my development site which has far fewer HTTP requests, and the time-to-first-byte is 1.6 secs and 0.99 secs for the repeat. (http://www.webpagetest.org/result/110205_85_33XQ/)
Am I on the right track or is there anything else I should be looking at too? (Apart from items highlighted in the report. I keep wondering if there might be an .htaccess problem.)
