Tweaking may be a disease.
In the quest for speed I’ve moved my very long blogroll from the right margin to a special page of its own, Blogs I Read, and linked to it right under the banner at the top of the page.
This chops almost two more seconds off the load time, at least if the barometric conditions are right.
Just one more thing — really, just one more, honest — that I have to figure out: why, sometimes W3 Total Cache decides to reject the IE user-agent and instead of directing it to the amazon cloud server, sends it to my host instead.
The message (in reveal codes) is
Content Delivery Network via Amazon Web Services: S3: staticd.discourse.net.s3.amazonaws.com (user agent is rejected)
But there’s nothing on the list of user agents to reject that I can see which looks anything like IE. (Full list below the fold).
If you are curious, you can tell which version you got by looking at the source files and searching for “staticd” — if you find it, you got the cloud version; if you didn’t it all came straight from the source. The two versions are supposed to be identical, it’s just a speed issue.
List of user agents “rejected” — ie sent to Dreamhost hosted files rather than Amazon hosted files:
