Yeah, It’s very useful tool. I like it. External widgets on my blog are realy slow.
I would also recommend to use this online free tool – http://Site-Perf.com/
It measure loading speed of page and it’s requisites (images/js/css) like browsers do and shows nice detailed chart – so you can easily spot bottlenecks.
It’s very detailed and accurate, supports a lot of features like Keep-Alive and HTTP-compression.
Also useful feature is that this tool can measure quality of internet link of your server.
