I have no technical backing for this suggestion except that I’ve seen it work on two different operating systems with the Google Chrome web browser.
Accessing my self-hosted WordPress blog to add posts and do site maintenance, page loads were taking FOREVER. The media uploader was hanging too. I thought it was a plugin hogging resources so I disabled a bunch of them and it still didn’t really help.
Finally I cleared the browser cache and cookies and now everything is back to normal speed.
Ideas anyone? I’m running plugins only provided by wordpress.org and the latest version of WordPress and everything else.
