we're moving from apache to nginx + php-fpm + apc on linode. as well as all the stuff recommended by pagespeed. jquery cdn, gzip, css sprites, pngcrush, js-min + concat, css concat, async script loading via LABjs. the improvement is quite remarkable. sometimes i blink and miss the F5 refresh flash and wonder if the page actually reloaded. craziness. one funny thing pagespeed tells me is that google's own analytics ga.js needs a longer expire time than 2hrs, they should fix that especially for scripts loaded from common cdns (especially their own) since web authors have no control over this.
