The load time of my website without W3 caching is between 0.3800 s and 0.4600 s.
But the load time with W3 caching is between 0.5600 s and 0.9800 s.
I have tested this with this code:
<?php echo get_num_queries(); ?> queries. <?php timer_stop(1); ?>
In the "Browser Cache," I have checked "Set expires header", "Set cache control header", and "Enable HTTP (gzip) compression". The "Cache Control policy" is set to "cache with max-age” and the "Expires header lifetime" is set to 31536000 for Media, CSS and JS files.
But I am still seeing this raports of Yslow and Page speed:
Grade F on Add Expires headers
There are 24 static components without a far-future expiration date.”
“Grade F on Compress components with gzip
There are 7 plain text components that should be sent compressed”
The same reports are given by Page Speed.
Any idea what I'm doing wrong
