.:Before You Upgrade to Yosemite Final:.

[spell87]

After many preliminary performance tests done on previous iMacs, macbooks with the latest Yosemite dev preview versions, I've concluded that if you own a mac computer older than two years old, don't upgrade immediately. Older apple computers takes a huge performance hit going from Mavericks to Yosemite. Wait and see if apple responds.

I'm running 10.10 on a late 2011 macbook pro and I disagree with that statement.

Though I should add I've tricked out that laptop with an ssd. But everyone should do that regardless of OS.

I've got a mid '09 running PB 6 and it is much quicker than Mavericks. C2D/8GB/500GB HDD...

I have a 2010 27" iMac with SSDs and i agree with his statement, it feels slower, no idea if it's actually slower though heh.

I have a mid 2010 mac pro and yosemite is way faster than mavericks. But that is probably because I have 8 GB of RAM and a Radeon HD 5870 graphics card from when i used to play WoW

All kinds of maintenance and indexing processes occurs after a major update. Give it a day and then restart and you should see a difference.

If this was true longterm wouldn't there be threads about this from the months of beta testing? I haven't seen any threads, so I bet it's maintenance tasks like others have said.

I tried one of the beta versions, 2 I think, on my 2008 iMac and saw no noticible performance hit. I did run into a problem with Mail and one where Safari Share button says No Services and that is why I'm back on Mavericks and waiting for a while whilst reading all the others complaints for a change.

 

[TitanTiger]

When I was running the public betas Yosemite always felt quicker on my 2009 iMac. But I also have the RAM maxed out at 16GB.

 

[KALLT]

Yosemite doesn't run noticeably slower on my 2008 Aluminium MacBook. It takes a wee bit to longer to launch, but overall I don't have any performance issues.

 

[poiihy]

I have been using Yosemite since first beta. I had no performace issues with it. it is no different than Mavericks. Mine is Mid-2009 MBP.

I'm running Yosemite since DP 4 on a 13" MacBook Pro Late 2011 and this is way faster that Mavericks.
