It's not just you, and it's not just Safari. I use Firefox for everything, but have to keep Chrome installed for the Google products I'm forced to use for work. I don't know if I can accuse them of intentional sabotage, but they certainly don't do performance testing outside their own browser.
I don't use Google products in Firefox or other browsers often enough to notice or care about performance but some say spoofing the UA string to chrome fixes many of those issues.
Wouldn't that cause positive feedback in the analytics? Firefox usage is already below the magic 5%. If we start hiding, we may soon join IE5 in unsupported land.
