Bob Wyman of PubSub suggested that I should add in the Google Blogsearch ATOM results to see if it any faster than the HTML results.
The answer: they might be. But they aren’t.
Why not?
Some bright bulb at Google’s Blogsearch team hasn’t enabled HTTP Compression on the XML results.
Boys, go back and check your config file and make sure that the text/xml (maybe even text/*) MIME-type is enabled for compression.
Then we will have a race on our hands.

You know it’s going to be a good day when the DBA comes up to you and says:
“You know those really huge and stupid queries that we always yell at you about? Well, we have some database hardware in place and we thought of you as someone who could stress the system.”
Fast hardware. Fast Drives. And a query headed quickly towards the 2-3 million row count and 10 minutes of running time.
I love abusing hardware.

At my real job, we monitor and report on the performance of a number of different e-commerce verticals.
[I will now try and stop using marketing-speak.]
In the retail index, the Gap has been down for nearly 3 weeks. Well, they have come part way up, but it is flaky, and they don’t have a search function.
No search function? Oh yeah, let’s go shop somewhere else.
Anyway, Erick Schonfeld at Business 2.0 just linked to a story at adfreak about this little re-design outage.
20 days. And counting.
This is unheard of in the Internet economy. Well, not unheard of, but the only other site I know that had a similar re-design outage was Wal-Mart back in 2000.
The Gap is a savvy online retailer. Why couldn’t this been done in a more intelligent way? What has made this re-design so problematic?

The weekly GrabPERF Search Index Results are in.

I upgraded b2evolution yesterday to 0.9.1, which the developers claim had substantial performance improvements.
I believe them.

Kudos to the b2evolution team!

Now it’s your turn to suffer with this.

CEMETARY POLKA
Tom Waits
Uncle Vernon, Uncle Vernon
Independent as a hog on ice
He’s a big-shot down there at the slaughterhouse
Plays accordion for Mister Weiss
Uncle Biltmore and Uncle William
Made a million during World War II
But they’re tightwads and they’re cheapskates
And they’ll never give a dime to you
Auntie Mame has gone insane
She lives in the doorway of an old hotel
And the radio is playing opera
All she ever says is go to Hell
Uncle Violet flew as pilot
And there ain’t no pretty girls in France
Now he runs a tiny little bookie joint
They say he never keeps it in his pants
Uncle Bill will never leave a will
And the tumour is as big as an egg
Has a mistress, she’s Puerto Rican
And I heard she has a wooden leg
Uncle Phil can’t live without his pills
He has emphysema and he’s almost blind
And we must find out where the money is
Get it now before he loses his mind
Uncle Vernon, Uncle Vernon
Independent as a hog on ice
He’s a big-shot down there at the slaughterhouse
He plays accordion for Mr. Weiss

Buy Rain Dogs. End my suffering.

Ok, the site is now running b2evolution 0.9.1 — took some swearing and a weird hack to get it to work, but we’re back!
If you see any weirdness, let me know.

This morning, I asked the ERTW.com measurement location to turn down, as we have completed testing the remote measurement code.
This will have some effect on results going forward, mostly positive. The ERTW.com location had an unusual DNS configuration which was affecting the overall measurement statistics.
I am still recruiting for measurement locations on the West Coast. Drop me an e-mail or leave a comment if you are interested in hosting a measurement location on your linux server.

I watched part of Fatal Flood last night. It was brutal. And, unfortunately, was echoed far too recently not to be a disturbing insight into the nature of the American mind.
The attitude in this nation towards the disadvantaged and disenfranchised has not changed since 1927. This country is falling away from the city upon a hill, the emblematic vision that fuels the misguided and selfish leadership of the United States.
Katrina exposed the raw, festering wounds in the United States. The stench from the Delta is the rotting of the American Soul.

Greg Gershman from BlogDigger found a bug in the Index charts just now. Seems that the chart legend was out of whack with the lines on the chart.
Easy fix. Turns out I was submitting the test ids in a random order. The graph generation component was fine with this, but when I went to build the legend, MySQL ordered the dynamic legend build result in a proper ascending fashion.
Simple fix: when I convert the test ids to an array, I sort the array before proceeding.
Thanks Greg!
