I know there are lots of threads going on TTFB in this forum.
But my query is regarding the TTFB increased in repeat view, presumed it should be the reversed. I had gone thru the page code and there is no unusual thing notice which increased the time in the repeat view.
My test is http://www.webpagetest.org/result/120723_KK_H90/
Any valuable comments will be appreciated.
Is it consistently slower in repeat view?
You might just be looking at an instance of highly variable performance with the repeat view test happening to take longer.
If it is consistent then I’d look at any code that acts based on cookies being present. If the server is doing user tracking or trying to customize content then that could be a cause for repeat views taking longer.
