Yesterday Google announced a new HTML 5 based tool for web based communication and collaboration called Wave.  One of the coolest things about Wave is this is an open-source project, anybody can embed waves in their site and build extensions using the Google Wave API.  The protocol called the Google Wave Federation Protocol  is based on XMPP (Extensible Messaging and Presence Protocol). Reading the documentation on the protocol I immediately started to think about what impact these waves will have in environments with Application Delivery Controllers: What load balancing method is best? What about persistence? Can the content be compressed? Are the waves cacheable? Can the encryption be off-loaded from the servers to an application delivery controller? I'll be intereste... (more)

Faster Loading Blogs

I maintain a personal blog on Blogger and was pleased to recently see an article on how to make my blog load faster.  Being an acceleration junkie I was very interested in what was recommended given that many of the items that typically influence the load time of a page are server side configurations which I have no control over with a hosted service like Blogger.   Some of Blogger's recom...

Bing Vs Google - A Performance Perspective

Being the total acceleration junkie that I am the first time a new site is launched or recommended to me the first thing I do is take a look at the performance of it.  So when I heard about Bing the first thing I did was fire up HttpWatch and take a look at the site.  To make things a little more interesting I decided to compare the results to Google, I used the classic home page and not...

Acceleration ABCs - X is for XML

I am frequently asked what can be done to accelerate XML.  There are two ways an application delivery controller can accelerate XML: Compression - XML is a markup language that is text based.  Text is easily compressible and can result in significant savings.  Dynamic Caching - If the XML is repetitive it can be cached, if each and every XML request is unique then caching is not going to ...
