Hi,

I made a lot of test but I receive different results and don't undarstand why.

With www
1. http://www.webpagetest.org/result/100720_1KMX/
2. http://www.webpagetest.org/result/100720_1KMH/
3. http://www.webpagetest.org/result/100720_1KMQ/

Withouth www

2. http://www.webpagetest.org/result/100720_1KMJ/

1. The first question is why for tests with www. some or all files are cookiless and for tests withouth www all files have cookies ????
2. The second question is why somethimes in the Connection View files are served only from investx.net and other thimes are served from http://www.investx.net also?? And this it seemes that don't depend if the test is made with or withouth www.

As I can see very big differances aren't between tests, but I also want to know what is the best solution??

1. Withoth cookies ( as I can see from comparations it seems that test with cookies are sometimes faster )..
2. With files served only from http://www.investx.net or also from investx.net. (neither here the tests aren't clear ..in some cases when files are served only from investx.net it seems it is faster ...)
