Where I live, in the northern hemisphere, we're at that point in winter when I start to come out of hibernation and look around to see what's new. It turns out, there's a lot of news in the performance world, which I'm excited to share in this letter.
I hope things are well with you, and that you have just the right amount of newness in your world. :)
Until next time,

This is a fantastic post from Conor Malone at Gumtree. (We pride ourselves on maintaining a pretty great Support Centre, but we love it when our customers write how-to articles that are even better than ours!)
In his post, Conor covers things like:
How does your site rank against your competitors?
I was chatting recently with some folks at a well-known media company, and I was pleasantly surprised to learn that they use our Industry Page Speed Benchmarks as an important competitive benchmarking tool within their organization. So I thought it might be a good idea to give a short primer/reminder here.
