I am also finding very slow loading of Atahualpa - 3-4 seconds, see
http://wordpressacademy.biz, some other themes I have seen load in a second even with lots of data (although I would have to install on my site and test and I can't do that right now.
Unlike the user above, I installed w3 cache and it made no difference, despite verifying that it works and that some things are accomplished (like minifying the html, css and javascript. So it's not a host-side execution or CPU problem.
I run Firefox plugin Page Speed and it reports 6 javascripts, about 20 non-cached images ("expiration not specified"), and 3 css. This doesn't sound too bad, but why is it so slow?
Could the 20 non-cached images be the culprit, should I contact my host to see about that?
Is anyone here getting page load times of less than 3 seconds on their Atahualpa sites? If so please let me check...
