Visual Round Trip Analyzer – VRTA

I come across this tool from my colleague. It is pretty interesting especially for public internet site or intranet site operating over low bandwidth.

“The Visual Round Trip Analyzer tool helps web developers and testers visualize the download of their page, identify best practices and changes that improve web performance. The network Round-Trip between the client and server(s) is the single biggest impact to web page performance – much greater than server response time. VRTA examines the communications protocol, identifying the causes of excessive round-trips, and recommending solutions. Performance engineers, testers, developers, operations personnel should use VRTA to conduct their web performance analysis”

It provides detail performance analysis and overall score rating. The results are more comprehensive compare to firebug in Mozilla FireFox. My seems get pretty bad rating. Time to change hosting company? :P
