AJAX and Web Performance Improvement: How do you measure it?
AJAX is an amazing bit of technology, and a boon to Web performance.
The question is, how do you accurately measure it?
Now, from the perspective of synthetic transaction measurement, AJAX destroys the foundational concept of the “Page”, as it is built on the concept of the “sequence”. “Pages” assume a whole new HTML document is loaded in each step, where a “sequence” simply tracks the specific flow of steps that the customer performs, regardless of whether they occur in a new HTML document or not.
In this respect, passive monitoring services currently have a distinct advantage over synthetic measurement, because they intrinsically track the sequence of event that a customer triggers, rather than the pages that are downloaded. I will not declare the death of synthetic Web performance measurement yet (my day job is with one the largest synthetic Web performance measurement companies); but the industry has to re-evaluate many of its core precepts.
AJAX is a technology that will definitely benefit from the blending of passive and synthetic performance measurement into a single usable stream of information that companies can act on. With this blend, companies can determine how their servers are responding, as well as what customers are doing, tracking the flow of business data in real-time.
What will be interesting to watch is how the synthetic measurement companies (including the one I work for) respond to this. One of the companies in our space says that they handle it now, but I have yet to see the results of their effort and how they really implement it in the field.
How are you and your team measuring the performance of your AJAX applications?

How much of your bandwidth does RSS consume?
Yesterday I was on a call with a customer who flat out stated that 55% of their bandwidth was consumed by applications pulling RSS feeds.
Does your company have a grip on just how much continual background noise RSS feeds inflict on your Web servers?

GrabPERF 2.50 Enhancements and Improvements
I am starting to lay out the new items that I will be rolling into GrabPERF 2.50, set for release in April. Already some friends of GrabPERF have weighed in with their desires, and some of them are easy to do, others require a whole new learning curve for me to get ramped into.
What I need from all the folks who use the system right now are the things that make you nuts. What don’t you like about:
- Graphing
- Data Presentation
- Workflow
- Available Statistics
This is your time to speak up because you use GrabPERF far more than I do. And without feedback, I just write in the stuff that is interesting to me.
Looking forward to the give-and-take.

Two Fisher Space Pens — GONE!
Last spring I bought two Fisher Space pens: one matte black; and one shiny purple.
Yesterday, I lost the last one, the black one.
Back to the Pilot G2s. Don’t feel so bad losing those.

GrabPERF Quarterly Pledge Drive
Time for me to launch the GrabPERF Quarterly Pledge Drive.
This is the part I hate. As I have noted in the past, I can’t charge for GrabPERF in any sort of traditional business sense. But I am also not doing this for a pat on the back.
As always, any donation, no matter how small, is appreciated.
I am also looking to add to my corporate spnsors list, so if you or your company is interested in achieving this much sought after position, drop me a note.
