About four years ago, I published/posted a number of indices related to GrabPERF data. This is a re-launch of that, starting with the GrabPERF Search Performance Index.
The methodology of the Search Performance Index is straightforward: A number of key search providers are selected and HTTP GET requests are sent that directly pull the results page [...]

For a number of years, I have owned three very popular domain names: WebPerformance.org, WebCaching.org, and WebCompression.org. Last night, after many days of consideration, I stopped pointing them at their own distinct Web space and pointed them at this blog.
This is not a bad or evil thing, considering that for at least 18 months, the [...]

One additional changes was made to GrabPERF today. The homepage with the Top and Bottom Performers, has been changed from a dynamic page to one that is autogenerated every two minutes. This graph should explain why.

The dynamic page was starting to push 20-25 seconds just for the Top 20 List. When I switched to the [...]

The GrabPERF Retail Web Performance Index is an extension of the Holiday Performance Index created for the Black Friday/Cyber Monday craze in 2008.
There is a methodology statement explaining more about the index below the data table.
Please add any comments or questions to this post.

On the weekend, I upgraded the database engine for GrabPERF to Mysql 5.1 and switched the main data table from MyISAM to InnoDB.
The switch to InnoDB was done because of the locking issues that were occurring during long queries, especially when doing ad-hoc analysis. The row-level (versus table-level) locking of InnoDB has removed most of [...]

Budgets are shrinking. Resources are tight or shrinking. In a recent post, I discussed how ideas that I had been a proponent of for 2-3 years suddenly became extremely valuable to companies during the downturn of 2001-2003.
This downturn is a different beast. This means that you will need more than basic technical smarts to get [...]

Over the space of two years I have created a series of posts that explore the analytical and statistical concepts that compose the foundation of a solid Web performance strategy.
These mark my attempt to move from a purely technical analysis of providing a solution to the problem at hand. These posts move my approach to [...]

In the end, it’s all about performance. And when times get hard and budgets get tight, performance should be high on the list of online businesses.
The issue that I see when I work with online firms is that the first item to be on the chopping block is the performance budget. Performance appears to be [...]

Service Level Agreements. SLAs.
Three of the most contentious words, and most contentious acronym, in the technology sector. Arguments are had, suits are filed, and relationships broken and strained as a result of this single concept.
