Interestingly, we made some serious speed improvements to a site of ours last month (about 100% speed improvement). I had expected to see the speed at which Googlebot was crawling our site improve but it actually got drastically worse.
Then low & behold, as soon as the new algo update rolls out Googlebot is blazing through our site at pre Jan speeds.
Looks like they were using some pretty serious resources to roll out this new algo change, which makes me wonder about how easy it'll be to tweak/correct in the coming weeks.
