Lion is very slow please help!

It sure is faster with 8Gb, but that's what I have on my iMac27@ since the beginning. And it is a slow Lion.

I have a 27" iMac with 8 GB RAM - dog slow - spends eons spinning the pizza wheel. Activity monitor says nothing is busy. What the bleep is going on? 10.7.3 seems to have been a tragic upgrade. Disk access is exceptionally slow. Folders take seconds or almost a minute to open. Renders the computer near useless. Web pages won't load, Safari goes away and spins the pizza dish. I have Textedit files that won't even edit because the program never comes back from a paste operation. I have three files that keep showing up each time I reopen and force a quit to Textedit.

This ***** (insert short curse word here...). I have to regularly kill Safari Content in Activity Monitor to keep the system running. Most issues seem to come back to problems with disk access.

Hey Apple - you have to be aware of the seriousness of this bahavior. What are you doing about it?

Then your problem goes well beyond memory. I run Lion on one MBP with 3GB RAM and use it heavily and it is as fast as ever. Yours sound like a more serious disc problem so it may well pay to start another thread. This one has been marked as solved which tends to sreer people away from adding any further attention to it.

My old MBP 3.1 from early 2008 was very slow after installing Lion. It started up ok, but slowed down after 10-15 minutes.

I tried everything from clean install to SSD-disks, but still the same problem.

The MBP had 6gb of Ram and after a tip from a friend of mine who is a IT-tech, I removed all RAM, and installed 4GB with new RAM.

(Everymac says it can take 6 GB of RAM (i did the firmware-upgrade) and Apple says max 4 GB.)

After that, Lion is lightning fast with no problems at all.

The techguy had no explanation why, but he always did this trick with MBPs that had the same problem.

So maybe its worth a try?

Having to buy new RAM because of an update!!! Apple rules!

I have a MBP I7 15" with 8GBRam, 512 Mb Video, mid 2010 model. Installed, I have Adobe Complete SW for Photografy, Office for mac, Parallels 7.0, Skype, Firefox, Lightroom, and all the original SW for Mac. All off those SW where already installed when I upgraded to Lion.

After 9 months trying many things, like memory upgrade (from 4 to 8GB), re-changed memory thinking that this could be a memory problem, uninstalling and re-installing many SW like adobe, safari, skype, office for mac, cleaning memory, disk utility, mackeeper, and many others, I can say that the speed increased like 40%, but is almost 50% slower than snow leopard.

Now is taking about 1 minute to turn on the computer, minimal 30 seconds to open any program, 3-4 minutes to open office for mac, 1-2 minutes to shut down the computer.

Last month I changed the Idea of buying a Mac for my whife and bought a Vaio. And I really loved Mac !!!! But now if someone asks me about it I'm not so confident of saying that mac is Unique.

Nowadays I'm waiting patiently for a new version of OSX, mostly because I really have no Idea what to do.

If anyone have a miracle answer, other than written above, please, feel free to write.

I also went to a Mac Center severall times and they have no clue about it. The only way they suggested is to format everithing again, buy a complete version of Lion, not the upgrade, and do a clean install .... but I don't have 1 week to configure everything again !!!!

I would suggest that you uninstall MacKeeper and see it the speed improves.

Upgrade as opposed to update. Big difference.

Pete

So ? It is not a matter here of adding RAM, but of changing it !!!

I actually reduced the amount of RAM, maybe that's the trick on this old version of the MBP (3.1)?

From 6 to 4 GB. But I'm not shure this will work on newer MBP's.

Already did that ... Tks anyway

Grid you google or search here for the proper method to uninstall it? Any other method will not get rid of all it's destructive elements.

Petermac87: looking at the Console listings, the most repetitive error is like this: "4/22/12 2:44:44.000 AM kernel: IOSurface: buffer allocation size is zero" - note that this seems to be a disk related error, consistent with most delays being related to disk accesses. Googled it, and came up with a 'known problem' related to Adobe Flash player. Don't know if that is totally responsible, but killing the Flash process with Activity Monitor helps with latency issues. Still think Lion is 'pokey', and has its own UI speed issues. Reminds me of the first 128 KB Mac, with OS 1.0. Couldn't wait to get upgrades.

Choir question being?

Maybe you did, maybe you didn't. Depends how you did it. Have a look here:
