Scrolling in Lion is so slow!

UPDATE

Scrolling is fine. But I just have to make sure that the webpage is FULLY loaded. If its halfway or even 99% loaded, the scrolling is jumpy.

If you don't have scrolling problems can you please try scrolling while the page is almost loaded and report?

I know many will say why would you scroll if the page is only 99% loaded. Well, safari loads most the page, and at that point i can tell the point i would like to scroll to. However, jumpiness will occur if you do this.

first, any connection that I'd ever use my MBP brings pages up so fast that it might be hard to duplicate that scenario..

second, i attempted to do it - and yes it does lag..but, only for a tenth of a second until the page is fully loaded and then scrolling immediately smooths out.
 
Having this issue with MB Air only

Greetings everyone - 1st time poster attracted to this thread by the same problem.

I have a 2009 iMac (Core2Duo, 8gb RAM) at home, a ~2007 iMac (slower C2D, 4 gb RAM) at work, and formerly had a 2010 MBP (C2D, 8 gb RAM, SSD), all running Lion just fine. About 1/20 of a glass of water (doh!) killed the MBP, so I replaced it with a MB Air a week ago. Only the MB Air has this problem, despite having the same amount of RAM and a much faster processor than my work iMac. Safari seems to be the main culprit, but even stopping it doesn't fix the problem - I have to not start it in the first place. Now I'm using Chrome and it seems better, but hopefullly Apple will fix it soon. It is giving me 2nd thoughts about the Air (which I have a week left to return), though I'll admit that finding complaints in this thread from new 17" MBP owners is making me think I should hang tight for a fix.
 
What I've noticed, is that jittery scrolling and other pinwheels in Lion are related to not CPU processes, but HD access. I have iStat menus installed, and for the first time in many OS versions I was forced to turn on the HD indicator lights. Every time the HD is read from vigorously, the system hangs for a moment, whether it's window scrolling or opening or closing. I get a pinwheel on the cursor until the HD access is finished.

Just visit System Preferences, Universal Access, Mouse & Trackpad and then Trackpad Options or Mouse Options...change the speed to whatever you prefer and be done with it.

Have you read the thread? This isn't about nice responsive scrolling at a slow pace. Its erratic, jumpy, unresponsive scrolling.


Thanks for trying BRLawyer.

What else you want me to say? I have no such problems here. It's either Universal Access preferences or a conflict with third-party mouse plugins.

Otherwise, it's just people not waiting for the full page to load...it has always been "jumpy" when pages are still loading, ya know...:rolleyes:

As I said previously, the problem seems to be aligned with heavy disk I/O. Every time the HD reads or writes like crazy, (due to another task like Aperture making previews or MobileMe indexing a sync) every finder and safari window becomes almost impossible to scroll in, until the HD task is over.

That is not the case with me. It slows down over time without heavy disk use.
 
Knock on wood, my issue was solved with the MBA-specific 10.7.1 update. For any other Air owners, be sure you use that update and not just the 10.7.1 that comes up in Software Update. The general one didn't fix my problem.

Never mind, I spoke too soon. While it was fine with about 18 tabs open and 10+ apps, after waking from sleep the same jerking scrolling is back. Doh.
 
Well nobody seems to be posting in here anymore but me, but in case others are following looking for a resolution...

I spent about an hour with a Genius today and my problem is solved. He deleted a lot of old software (no longer used, copied over from old MBP) that was loading in the background that I couldn't see. Step-by-step, deleting things didn't work until we deleted...AirDisplay and Norton Antivirus (which work requires me to have). Several other apps that load in the background were deleted around the same time so I can't be certain about the culprit, but he thought it was AirDisplay. I guess it makes sense, right?
 
I've never seen slow scrolling in Lion - other than in Safari. It's so painful at times, however, quitting the "Safari Web Content" process in Activity Monitor does make a difference until it comes back. It appears to be some sort or cache-like facility where it just grows and grows until the size of it starts to affect the performance of Safari itself. Really poor development in my opinion and unacceptable. I will see if 10.7.1 makes any difference and report back

Hi jcg878, I'm having the same issue as you had it - will try to find more old programs that I don't use anymore and try and remove them from my Mac. Do you know what the Genius did do exactly? I suspect I have some traces of Parallels and BTT left behind on the Mac which cause the jerky scrolling in performance problems in Lion after waking up from sleep.

Thanks for your hint!

Regards:)

He was working in terminal to erase traces of various programs that boot up with the OS - mainly those things in the menu bar, but also programs like Parallels that load without being obviously activated (incidentally, my Parallels doesn't work now and I will be reinstalling it). I'm 99% sure it was AirDisplay on mine.

He told me what he was doing all the while, but he was flying through it and I couldn't keep up. One important note - he thought it had uninstalled several things that traces of them kept re-loading on startup, so even if it doesn't show in the menu bar, there might be some remnants affecting things. Good luck!

Well, scratch that. About 6 hours later, the jitteriness started again. I'm formatting and starting from scratch.

Be careful about what software you reinstall. My bet is that something you've installed is causing it. The behavior is definitely not the way it should be.

I bet that a lot of people complaining about how slow Lion could very well be traced back to this situation where old software running is causing the problem. This is one reason why I like to do clean installs as it gives me a chance to do some house cleaing with my Mac computers. Doing a clean install is not required but can be a good practice when it comes to new OS releases.
 
Sure, it's always good to do a clean install - but it's all a matter of how much time one's willing to invest into his/hers computer. I don't want to do it, because I need all settings, programs, licenses, as they are... ;) But nevertheless, good point!

BTW, I made a little video that hopefully shows my issue:http://www.youtube.com/watch?v=DCKkGjgXFTU

Did anybody with the scrolling problems have success with installing the iMac firmware update? Don't think it helps, but I'll give it a try this evening...

http://support.apple.com/downloads/DL1444/en_US/iMacGraphicsFWUpdate3.0.dmg
 
I never had the problem on 2 iMacs running Lion. Neither of them have ever run AirDisplay or Parallels though, but both have Norton AV.
 
I tried to install the iMac Firmware 3.0 Upgrade from Apple, but it didn't install. My system is not supported, so this little thingy is not solving the laggy scrolling... I'll keep searching for a solution.

Thanks very much!! That solved my problem. I installed AirDisplay yesterday and this whole morning, I've been trying to figure out why Safari doesn't scroll smoothly after waking from sleep. It does now that I've gotten rid of stupid AirDisplay!!!

Glad to help! I reinstalled Parallels and it is scrolling fine after sleep, so between your experience and mine I think we've found the problem.
 
Safari scrolling delay

My Safari would delay scrolling.....( maddening ). I just noticed it slow today even tho I have had Lion for a while. But today I had downloaded several Safari Extensions. So I turned the extensions OFF and now my scrolling is as it should be. Just say "NO" to Extensions.

Interesting Litldannyh,

i just turned off all but two that i don't want to give up. I then restarted safari and it seems to load MacRumors and web pages a lot faster. I believe this will help alleviate scrolling issues but i don't want to speak too soon. So far so good!!

Thank you.
