I installed Lion on a relatively new MacBook Pro (released early 2011) with an i7 dual-core processor. It is painfully slow, much slower than Snow Leopard was. Even things like surfing the internet (using Firefox) is very slow, and I see the little rainbow circular icon frequently.
Any ideas?
MacBook Pro, Mac OS X (10.6.7)
How long since you installed? sometimes spotlight will take a long time to index your drives and slow your computer down a LOT. Are you backing up with Time Machine? That can also slow down the computer until the backup i done.
APierce,
You saved my machine and my sanity WITHOUT my having to erase and re-format the laptop. This worked!
(15" Macbook Pro, 2.33 GHz Intel Core 2 Duo, 4 Gigs 667 MHz DDR2 Ram)
My laptop works like it did before Lion.
This seams to have done the trick.
Thanks for sharing!
Spoke too soon. Tried to rebuild my Mail folders and Lion vertualy stopped working. Had to force shut down. I think I made a huge mistake by upgrading.
hehe! 🙂
for some reason Lion is now running well on my mac O.o
I really did NOTHING! And suddenly i have the same benchmark results like in Snowleopard! CPU Power jumped from 50% zu 100%...
nice feature ^^
I found an interesting fix that could help people who are suffering from slowness, specifically if you are using Boot Camp and if you've noticed that one of the processes eating up the CPU is Finder.
Turns out that Mac OS X was continually trying, yet failing, to index and search my Boot Camp drive, and this was causing much of the slowness I was experiencing.
How did I disable this?
1. Go to System Preferences
2. Select Spotlight (2nd icon from the right in the top row)
3. Select the "Privacy" tab within the Spotlight preferences window
4. Click on "+" at the bottom of the window
5. Select "BOOTCAMP" (Or whatever your Boot Camp drive's name is).
This will prevent spotlight from searching Boot Camp. I did this last night, and since then my Lion performance has gotten MUCH MUCH better.
Hope this helps someone!
No Bootcamp here but thanks for the tip. All I know is what ever is running my hard drive like Windows Vista NEED TO STOP!!!
this problem ist NOT a Lion Problem!
It occurs when a NTFS 3rd party write program is installed... !
Then Mac OsX is able to index Bootcamp partition.
If nothing is installed --> Mac OsX will not "Spotlight"-Bootcamp partition!
Got this error already 3 years ago while using Snow Leopard with Bootcamp.
NC_Neo,
That may be the case, but before upgrading to Lion I did not experience any slowness resulting from this situation, or at least did not notice it.
This is a Lion Problem. I think I found it. Lion is paging too much to the Swap Disk. This make since. Any time you access a program and the memory for that program is on the hard drive it will take very long to respond. Snow Leopard did not act like this unless it need the extra space. I have 8 gig or ram and I still have problems. If I was running a SSD I might not even know the difference but I'm not.
Actually, I deal with this speed problem every day!!! 😢 and now with 10.7.2 my MacBookPro freeze like 3 or 4 times a day, and I have to turn it off (Forced) each time...
I wanted to share that I have two laptops: my new MacBook Pro upgraded from SnowLeopard to Lion, and a very old iBook G4 not Intel (with Tiger 10.4). A few days ago, I started both at the same time, and the iBook G4 load first!!! it was so funny 😢, I guess....
I have tried:
By the way, Microsoft Excel 2011 for Mac still being veeeery slow, it makes me feel embarrased...
...waiting for an upgrade to fix this speed issues...
does anyone recommends me a Benchmark App to test my macBookPro and post results???
The way Lion was changed to acts like the iPad and Iphone is just one of the steps Apple is making to move back to the ARM (Risk) processor like the G4 so it is not surprising that the G4 was successful. This is in my opinion of course.
On subject my gut is that the slow performance is a memory leak type issue. I have to reboot my Mac every so often for to run well again. If you leave your Activity Monitor open you will see memry usage in all areas grow.
Funny thing, if you look at this Apple support document you will see that they don't tell you what Virtual Memeory is and the memory colums are labled differently.
I just added up all the process in Activity Monitor and it totaled 4.812 GB of stuff out of 8 GB of ram but it only showed 30 MB of ram left. I closed VMWare which was using 3.33 GB but I am only up to 551 MB and it is falling slowly. Lion seams to eat ram untill it gets down to almost nothing then stops. You are ok untill you load another program then your computer is almost useless until a reboot. I can't find the lost memory so I can't find a fix other then a reboot.
I hope Apple is on it. This issue is killing me!!!!

Why is Lion so slow?
