Hello,

I have a 15k rpm server 16g ram on which is fiercely installed nginx  
1.5.1  
on a debian 7 machine (no apache installed).

I read a lot (up to crunching my head) about caching strategy.

I would like to reduce the latency of file serving.

currently, my webpage (static html) loads in 43-70 ms but then 44ms are  
spent doing nothing then load the images.

The total for a 120k page is 500ms.

What is bugging me is that even with 4 cookie-less domain (actually same  
disk) the answer is always page load + 44 ms idle.  
So not a browser limitation.

How could nginx cache the images so that the answer be really fast ?  
proxy\_cache is useless in my case, isn’t it ?  
Varnish would maybe help but it is something on the stack to debug when  
things go wrong. Not really a solution.

Thanks,

From your description it looks like 44ms is a time spent by a  
browser doing something prerequisite (parsing the page? resolving  
dns names? loading some external javascript?).
