With any luck, I have just man­aged to speed up the time it takes to gen­er­ate my blog page. It should now be almost three times faster than before. I man­aged to nar­row it down to the ‘posts_nav_link()’ func­tion which gave the ‘older posts’/‘newer posts’ links at the top and bot­tom of the page. These were tak­ing as long to execute as the main blog loop (in fact they run almost the same data­base query). So for now they have been removed, which means you must use the archives, cal­en­dar, or cat­egor­ies links to nav­ig­ate to the older posts.
