I just installed my site on a vps...
Testing performances in xp I noticed the browser (firefox 2.x) was reloading each small image and the render of each page took about 10 secs. and navigation in backend was a pain
I checked cache settings in options, it was all right set. But FF was not caching.
Then I typed in adress bar:---> about:config
and I discovered cache was disabled!!
I enabled it setting:
browser.cache.disk.enable default boolean true
browser.cache.disk_cache_ssl default boolean false
browser.cache.memory.enable default boolean true
default settings was altered, I don't know how!
now pages reload in less than 1 sec.
then I checked my laptop with Vista and FF 2.x
and guess what? same story!
I'am asking how it could happen, and if we have to tell to our user to check that setting!!!
