In theory youtube embedding is done as iframes, and iframe are virtual additional independent web pages which are rendered at the same window, therefor the content of one iframe can not gave an impact on other iframes.

If possible get your PHP updated to the 5.4.x branch. Before you add your caching layer you need to determine whats slowing down MySql and PHP. You need to enable WP_Debug and eliminate any PHP errors. Look for undefined indexes, syntax errors and deprecated functions. That 20 second to first byte is all PHP, MySql … Read more
I’m probably overcomplicating things. Right now, you are. As I have no traffic as of now I don’t really need to do this, but …. I don’t know what to choose as I don’t understand what these services really do, other than it’s supposed to be “better” to host externally… Then why bother with a … Read more

wptexturize() (in wp-includes/formatting.php) tries to convert typewriter quotes ” and ‘ into typographically correct pendants like “ or «, depending on current translation files. If you cannot type correct quotes, you should not disable it. There are some related replacements for dashes and ellipsis (not localized for whatever reason). All these replacement are done with … Read more
I’ve developed a 55k product ecommerce site using WordPress with the Shopp plugin and can share what I’ve done to MySQL to eke out better performance, YMMV and some (or all) of these may not apply to your situation. Determine how much you need to increase buffers/caches by by looking at the output from a … Read more
It’s really simply GoDaddy and slow mysql and webservers. I’ve heard apocryphal stories of people making lots of noise to GoDaddy support and as a result, speeds improve. Do they get moved to better servers or get priority load-balancing? Impossible to say. One other thing to try is http://wordpress.org/extend/plugins/use-google-libraries/ but sometimes it doesn’t help much … Read more
