In 2004-2005, as a lark, I created my own Web performance measurement system, using PERL, PHP and MySQL. In August 2005, I managed to figure out how to include remote agents.
I dubbed it…GrabPERF. An odd name, but an amalgamation of “Grab” and “Performance” that made sense to my mind at the time. I also never [...]

My system has a daily job to collect and aggregate the IP Blocks distributed by the five registrars into a single database, and then provide high-level WHOIS information for this data. If you want to try this yourself, the interface here.
On an extremely irregular basis, I aggregate the statistics from this data, and present it [...]

When I got to the London office, I started talking about how I had an addiction to sexy GSM phones, and showed off my collection. I then noted that the Motorola Razr seems to be a pretty hot commodity these days in London. My colleagues laughed, and one of them pulled his old Razr out [...]

Today, a new measurement location was added to the GrabPERF family. The team at Blog.com have graciously provided us with a server in Germany, and that is now online as Germany Blog.com #1.
We are still looking for measurement locations in the UK (or Ireland) and Asia.

A colleague in Germany forwarded me this interesting Microsoft knowledgebase article.

Internet Explorer May Lose the First 2,048 Bytes of Data That Are Sent Back from a Web Server That Uses HTTP Compression
This appears to only happen if another program registers (Real8 Download is the example given in the KB article) to use some of the [...]

Here are the IP Block and Address allocation by registrar, as well as the number of officially allocated IP Addresses in each country (with 65536 Hosts or more) as of September 22, 2005 00:30 UTC.
This data has been extracted from the GrabIP database

There is a slight chance that I could be going to Germany at the end of the month, so I need some help.
I am looking for reader comments/suggestion on a solid, robust, multi-country power adapter for my emergency bag (I fly off to foreign countries to solve Web performance issues almost daily — NOT!).
So far [...]

I made the attempt. No one can fault me for that. However, I was defeated by the twisted, anarchic madness that is the ARIN database.
A step back: I was considering refining the GrabIP database to more accurately reflect the true countries where IPs are used.
APNIC, LACNIC and AFRINIC are all sanely managed. Countries and IP [...]
