I just found out, much to my surprise, that none of the outlets where I have my oscilliscope are grounded. Would this affect performance?

Most likely not however, I would careful about using your scope on hot chassis.

It's certainly not safe but it's not going to affect the performance.

And how come you have 3 prong sockets with no ground connection?
Sureley thats against any jurisdictions code in this day and age. :-?

There are exceptions (grandfathered structures with a GFCI) but they should be marked as ungrounded.
Yes living in a country where 230 volts is the go and Grounded outlets have been the norm fo about 30 years and more in some areas, I forgot about the GFCI situation but as you say they should be labeled. A ground (green ) wire must go to every light fitting whether the fitting is metal or not as it might be changed at a later date. This was a recent (20 years maybe) addition to the rules.

It is generally beter to float the scope (no AC mains Gnd). If you want to test mains voltage with your scope if the probe is referenced to mains Gnd - good by probe!!!

"Better?" Isn't Australia where they sent all the criminals that they didn't wind up hanging? Where they have foot-wide spiders that want to kill you? And where God put together things from spare parts left over, and wound up with the platypus?? I mean, they named a whole *town* after Darwin...
Sure, we Yanks have our problems, but we're not doing so badly for a primitive country. There is every hope that we might have civilization here eventually.

We only had to take convicts after you lot could not handle the job. lol then we advanced quickly. No death penalty, Metric measure like the better part of the world, a debt to GDP ratio far and away better than most.

All true. Still, I refer you to this authoritative article:
Anyway, Australia is one of the very few places I wouldn't mind living. All those other places have too many foreigners.

That is extremely dangerous advice.
Especially when expressed in a public forum.

Save the probe and fry the user!
Agreed very dangerous advice! Testing AC line stuff is when you want to make sure the 'scope is grounded. I was talking with someone who hooked his 'scope ground onto the wrong side of the AC line... blew the 'scope input and the circuit breaker... but the ~$50 scope probe is still working.
