Why is Lion so slow?

How can I tell if I have the latest Flash? Where do I look?

Your read/write stalls makes me wonder about a failing hard drive. Hopefully, it was just a Parallels incompatibility.

I had a Seagate drive with known problems that eventually (prior to the warranty expiring, thankfully) started exhibiting stalled read/writes. Wiped and reinstalled, but got same stalls while restoring from backup. SMART status was Verified up until the drive stopped dead.

I don't think you have to have it running for it to be a culprit. Parallels installs kernal extensions I think. Perhaps then versions of Parallels which are not the latest have kextentions that didn't play nice with Lion.

(Take my comment with a pinch of salt; I'm not an expert here by any means).

again I don't think parallels is the problem, it could be, but I don't think so, I was also having this problem when vmware was installed.

the latest flash for os 10.7 is actually a beta, there's no official release, but I discovered a massive barrage of kernel messages in my logs that I've traced back to flash 11 beta. after removing flash my mac is stupidly fast compared to what it was. only time will tell if it's fixed. for those who want to help me test this theory, just use the flash uninstaller located here http://kb2.adobe.com/cps/909/cpsid_90906.html

I'm not sure if it's going to be the problem or not, but it is triggering a stupid number of kernel messages so it's a good first test.

btw, reason I don't think parallels was problem, removing it, nor a full update has solved it, and problem also existed for me long before installing it, can't be problem if it's not installed. it's possible it's causing a few issues but I'm not seeing a lot of errors from it

Adobe Flash Player version 10.3.183.5

I've had the latest version of Flash since Lion was released and have never had any slowness issues with Lion.

I might also add that I've at least 3 earlier versions of Parallels with no issues either.

What about that RIM software, what does it do?

yes lanny, I do not wish to sound rude, but you've said this multiple times. the issue may not be related directly to flash but rather a combination of software interacting badly. we know you're not having issues. But I do appreciate knowing what issues you do have, helps me get a basis for comparison to see what's differant between the machines. what kinda mac are you using?

as for me, after uninstalling flash I have noticed an extreme speed increase, but I do not know if it will last. my mac usually runs fast and efficient [but not this fast] for a few hours after turning it on, it gradually looses speed while running.

rim software isn't the problem, I don't have it installed at all and have major speed issues that I'm troubleshooting, the rim software is just to sync a blackberry with your comp

If you use the Flash uninstaller, does that mean you won't be able to access Flash? Or is there something you should be installing in its place after uninstalling?

it means no flash, correct. which since not a lot of the web is flash other than ads and a few games [discounting youtube and such] it shouldn't be a big loss, it can always be reinstalled after you check to see if it's the problem. so far my mac is still a lot snapier than before I removed it. I'm still not sure if flash will indeed be the problem but so far it's promising.

for those who want to try this for yourself, just use the uninstaller posted above to remove flash, if you still have problem please post it here and feel free to reinstall flash. if it fixes your problem please post that here too!

steps I took, ran uninstaller [had to quit safari] then rebooted once installer finished. now I'm just waiting to see result but since mac usually runs decently for first hour or two after turning it on, I'll just have to give it some time.

oh and steps to reinstall flash after test, if the problem doesn't go away... just click the install addon option on any given webpage that has a flash applet.

I repaired permissions on my hard drive, removed flash, and removed all unneccessary items from my startup file and things seem to be significantly improved. The real CPU hog continues to be Microsoft Outlook and I'm not sure when that issue is going to get resolved.
