Quarantined Conferences: Claustrophobic Technophiles or Attentive Audiences?
By Mark DrapeauNovember 11, 2009
Loren Feldman. 1938 Media. Audience Conference. That’s about as much of a summary as you’ll find about the Audience Conference held in New York last Friday. That’s because there were no open laptops allowed during the performances. There was also no Wi-Fi, no video streaming, no tweeting, and no blogging. Something akin to omertà joined the members of the Audience...
More on how web performance impacts revenue...
By Jesse RobbinsOctober 1, 2009
At Velocity this year Microsoft, Google and Shopzilla each presented data on how web performance directly impacts revenue. Their data showed that slow sites get fewer search queries per user, less revenue per visitor, fewer clicks, fewer searches, and lower search engine rankings. They found that in some cases even after site performance was improved users continued to interact as...

Announcing: Spike Night at Velocity
June 19, 2009
Guest blogger Scott Ruthfield is a Program Committee member of the O'Reilly Velocity: Web Performance & Operations Conference. Web Operations is not for the casual observer: it's for a particular kind of adrenaline junkie that's motivated by graphs and servers spinning out of control. Jumping in, on-your-feet analysis, and experience-based-experimentation are all part of solving new problems caused by unexpected user and machine behavior,...
Programming as Live Performance
By Simon St. LaurentJune 3, 2009
As I'm writing this, twenty people are watching their peers write code. They aren't looking over anyone's shoulders, or doing peer programming - they're watching mirrors of screens at the TopCoder Open, seeing exactly how competitors work their way through algorithm problems in C++, Java, and C#. Is this something we should be doing more of?
MySQL faster, better, and still unified: notes about Sun, Monty Widenius, Percona, and Drizzle
By Andy OramMay 22, 2009
It might have seemed last week, with the announcement of the Open Database Alliance, that MySQL is forking. The ODA promises a "central clearinghouse for MySQL development" and claims to improve on areas where criticism has historically been aimed at MySQL AB/Sun: bug-fixing, performance, and community responsiveness. But what's going on behind the scenes is much more subtle and promises a much better outcome for MySQL.

Linux Performance: Different Distributions, Very Different Results
By Caitlyn MartinMarch 9, 2009
I almost invariably get a comment to the effect that all Linux distros are essentially the same: running the same kernel, the same libraries, the same filesystems. Performance should be essentially the same, right? The answer is a resounding no. The performance results of different distributions, even ones running the same kernel version, the same core libraries, and the same filesystem can be very, very different.

New MySQL Query Analyzer for enterprise customers
By Andy OramNovember 19, 2008
MySQL AB (now Sun's Database group) established a multi-pronged business model long ago: support contracts, dual licensing, and proprietary add-ons all play a role in making them one of the biggest success stories in the area of open source business. Today their MySQL Query Analyzer adds another brick to that edifice. The analyzer can do simple things such as tell you how long a recent query took and how the optimizer handled it (the results of EXPLAIN statements). But it can also give historical information such as how the current runs of a query compare to earlier runs.

Audio Performance at 120 MPH!!!
By David JavelosaSeptember 30, 2008
Ok, it’s been 11 months since I’ve written in this blog. But guess what? I’m a new dad! If that isn’t life changing enough I’m not sure what is; except the following techno tale I have to tell. Through a strange intersection of factors, I was personally involved with a pretty interesting audio experiment, digital or otherwise. Let me crank...
I Accept the "One Million Records" Challenge
By Andrew TriceAugust 8, 2008
Earlier today, Richard Monson-Haefel posted here on insideria.com about the "One Million Record Challenge". I thought this was a pretty interesting test for any RIA platform, although it will yield wildly different results on different machines, and can't necessarily be used as a true benchmark. I decided to take on this challenge with Flex.
The "One Million Records" Challenge
By Richard Monson-HaefelAugust 7, 2008
SAP's Web Dynpro can easily handle loading 1 million records into a visual table and sorting them - so too can Curl. Can your RIA platform of choice handle 1 million rows in a table?
The Batmobile, Lamborghini, and my Suburban
By Richard Monson-HaefelJuly 23, 2008
When you choose a RIA platform you have to consider many things and in many cases Ajax, Flash/Flex, or Silverlight will do the job nicely. But there are occasions when you need something much more powerful and that’s when you should take a serious look at Curl.
Flex RIA Performance Considerations Part 4: The Display Hierarchy
By Jun HeiderJuly 16, 2008
Overview When building a Flex application, you need to consider the objects you display and how they interact with the end user, the Flash Player, and even the Flex Framework itself. Performance is all about doing things in the least...

What is Web Operations?
By Jesse RobbinsMarch 30, 2008
Theo Schlossnagle wrote a brilliant summary of one of the biggest challenges we discussed at the Velocity Summit in January:What is this Velocity Summit thing? It was a bunch of web architects from highly trafficked sites sitting around talkin' smack. It was operated in Foo style. However, one thing that made me really appreciate this meet-up was the lack of...
Forrester "Research" on AJAX Performance?
By Matt OsbunMarch 27, 2008
First of all, let me start off by saying that this is NOT another blog article in the great RIA platform debate. While I am an AJAX developer, and have been for several years now, the point of this article is not to take sides and convince you that AJAX is the best RIA tool available. Because AJAX isn't. Except when it is. You see, tools have uses, and to say that any one platform is in all ways superior is, I think, overstating things. A lot. Yes, I'm a bit biased, but not so much so that I feel the need to convince people that AJAX has no flaws. Flex and Silverlight have strengths that lay against weaknesses in AJAX, and vice versa. The question isn't “Which platform is best”, but “Which platform best fits my needs”.
Structuring Data and Serivces for Application Performance
By Andrew TriceMarch 26, 2008
Everyone wants their Flex application to perform well. We each want ours to be fast, with minimal wait times, and want it to run as seamlessly as possible. Well, one of the most important factors in getting this kind of response is the structure of your data model, and the results of your data services.
Flex RIA Performance Considerations Part 1: Getting Started
By Jun HeiderMarch 17, 2008
Now that you've had a chance to get your feet wet with Adam and Scott's outstanding InsideRIA series on Learning Flex From Scratch (LFFS) it's time to start really thinking about optimizing your apps. Many new developer are just happy to build an application that works without thinking of the consequences of poor architecture, inefficient code, and over-zealous eye candy. Although you may be fine for a while, eventually a lack of concern for performance is going to stop you in your tracks. Thanks to Murphy's law, this inevitability will occur most often on very large or important projects, and oftentimes after they're two days away from launch.

Flex Performance, Memory Management, & Object Caching
By Andrew TriceMarch 5, 2008
The responsiveness and performance of a Flex application directly relates to what is being displayed onscreen. The more that is happening, the slower the application will respond. In most cases, you won't run into this scenario. If you are dynamically adding LOTS of UIComponents, then this tip will help you create applications that perform very well under heavy load.
