I put Yosemite on a retina MBP which is my secondary machine. It is very slow, even DP2. On Mavericks it was lightning fast. I have it on a secondary partition so I can revert back to Mavericks if necessary but I really wanted to start practice developing swift apps for OS X. Even when the only software I have running is system preferences, I get the spinning beach ball when I click on any option in system preferences.

Does anyone else have this same issue with the beta? Any potential suggestions? I 100% expected an issue like this to happen and I can revert back to Mavericks easily, but before I did I was wondering if any of you had found a solution.

EDIT: fixed. It was a program called "Parallels Access" causing the issue!

well I can't help you with the BETA issue because Yosemite beta's don't exist yet so I'm not sure what you're installing there. But both Developer Previews that have been leaked work perfectly fine (speed wise) on my macbook air and pro.
 
It's not slow for me, also using a retina MBP. So far, with DP2, all the slowness I got with DP1 was been essentially fixed. I'm doing much better with memory too. Haven't gotten swapping yet for 2 days uptime, it was much worse with DP1.

Maybe you can try a reinstall?

Also in Applespeak DP == beta.

Apple calls build before a GM, a DP too. There's no release candidate, beta, alpha or anything like that. Unless people specifically mention the public beta, you should assume DP == beta.
 
Actually I find it very fast to boot. Other than that I don't do much else than Xcode in Yosemite, so I can't say. Anyway I don't find it any slower than Mavericks. Using 2011 MBP with SSD and 4GB RAM.
 
Very good, I will hunt down whatever I installed on the system that is causing the issue. I think it might be Parallels Access, it seems to dramatically speed things up when I've closed it. The Developer Preview was very slow when Parallels access was running in the background even when it wasn't in use.

I'm actually really impressed with the DP's so far. Pretty fast and mostly stable on my end, I can pretty much use them as my everyday system

There is nothing official about your opinion and trying to pass your opinion off as official is a joke. Additionally Yosemite has not yet been released and should not be on your joke of a list.

they are benchmark scores, not my opinion.
 
It was the new "Parallels Access" program causing the issue. Uninstalled it and now it's lightning fast. Back to Xcode!

Yes, in general old software tends to run faster than new software on the same system because it did a lot less and had a lot less features, it's not a huge surprise. Software with a lot less features, less functionality, and less compatibility will be faster. Also, what is "official" about this list of yours...?

I wish I could stay with snow leopard forever. That's the windows xp of the Mac world. Tried, true, fast, all new features to make you switch are meh.

Features like newer hardware support are meh? You can stay on Snow Leopard as long as you do it using hardware from the same time. Just like you can still run Windows XP but only old crappy hardware with 4GB of RAM.

If newer hardware doesn't feel faster, then what's the point?
