I have tested the new Second Life HTTP Viewer version 3.7.18.295372 today. All what I can say is: That's awesome! The new viewer is fast, faster, much faster! I have seen speed increases, which I would never have thought that's possible. Thank you Linden Lab! It's just a beta viewer but the new viewer completes the changes that LL has made in the last few months, comprising CDN, keepalive connections and HTTP-Pipelining. Read more about it here. At the moment CDN is not used in all regions. But you can test it for example in INSILICO. Install the new viewer from here, clear your viewer cache, set the draw distance to 512 meter and increase your maximum bandwith to 10000 kbps (normally you should not set it higher than 1500 kbps, but now you can). For me the complete region loads in less than 6 seconds. Without the new technology it takes more than a minute. That's really awesome. I have called the new viewer "Berlin" Viewer, because of the title of the article "The Sky Over Berlin" ;-) If the new viewer comes out it's a must for everyone. I'm so excited.
