I deleted Chrome 2.0 from my system on Friday for one very powerful reason: When it is installed, it makes itself the default browser.
Its performance gains and light weight were impressive. But its invasion of my system was uncalled for.
No matter which browser you set to be the default browser, Chrome 2.0 prevents that browser [...]

In the 10 days since its public release, MSIE8 has made a run up the charts. Courtesy of the great folks at StatCounter and their public analytics data, this growing browser share for MSIE8 can be easily followed.
In the US, prior to its release, MSIE8 RC1 was in sixth position behind even the old battleship [...]

The next generation of browser all tout that they are able to more effectively deliver on the concept of cloud computing and Web applications. That may be the case, but it changes the entire world of Web performance measurement and monitoring.

Tonight, I figured out how to add the Resolved IP Addresses for a host to measurement data and store that information for further debugging. It was very simple – I was trying to find complex solutions to this issue.
Turns out the solution is built right into PERL: The Socket module.
My thought is that I will [...]

DNS hijacking is an occurrence that sends fear into the hearts of man and beast. It takes a perfectly harmless (yet critical) process and turns it into a weapon for chaos and mayhem.
This tool, however, does not simply reside in the hands of people looking to maliciously redirect traffic for purposes I can’t quite fathom [...]

This afternoon, the two GrabPERF Agents at Technorati were switched back to using their local copies of caching BIND for resolving DNS entries.
Some folks at Microsoft who stopped by to look at their results on the Search Performance Index noticed that there were one or two outliers in the results from these locations. When I [...]

US data shows that MSIE 7.0 is in a dominant position, [...]

Via Statcounter, here is my search engine distribution for a log of 2,000 hits.

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.
