Lawrence "The Dreamer" Chen's Blog

There was griping today at work about how long it takes to load a page in a blog....~15 seconds is too long.

So, I got home and wondered how long does it take to fully load my site? ~30 seconds.

Though I thought that was a reasonable amount of time. Most of the page is fully rendered, its just some strange bits doing stuff behind the scenes.

I knocked out the Twitter widget...that shaved off ~10 seconds.

I then kept poking around....finally I knocked out the Technorati embedded code that I put to claim ownership of my own blog. Now it only takes 3-5 seconds for the main page to load.

Makes me think that maybe I could put the Twitter widget back, to see if the Technorati embed was making the Twitter widget code slow (since part a loaded before and part b loaded after). If only I had kept a copy of the code before I mercilessly hacked it out of my blog.

Wait...I blogged about adding the widget, so that might lead me to where the code is. Except that I tweaked the original code, and okay...I've figured out what quick kluge to make it mostly work again.

Hmm, ~5 seconds for the main page to load. Guess Technorati is out

OTOH, it was found out the thing that was making the blog at work slow....it was trying to talk back to itself through bigip, and getting all confused. Because selective SNAT is something we only do for the virtual servers that ask for it. It worked behind the old F5, because we had NATs for everything behind the F5...its the only way into that vlan (almost, there's some resources that are multiported, like the NFS server...but the NFS server isn't a router.) The New F5....has routed networked behind it (where the FWSM routes those vlans to the F5 which routes into the specific vlan).

Putting the iRule in place.... page loads on the order of ~1 second.
