    I have a macbook pro 7,1 mid 2010, C2D with 4 gb of ram running 10.6.8 (snow leopard).

    I just did a clean install of snow leopard the other day because mountain lion was giving me problems, updated everything and am using a 24.xxxx beta of google chrome.

    But within the past few days, I noticed every time I stream an HD video or listen to pandora within chrome, it starts to become laggy and choppy. It makes it so bad that it's unbearable to watch so I now resort to watching youtube videos on my Nexus 7 or on my phone...

    Any help or suggestions? I've already cleared PRam and have done a clean install as well as update all the drivers/whatnot.

    Here's a screenie of when I was running Facebook, Paused Pandora, full HD video on Youtube and one google search.
    The second image is just Chrome playing new girl in HD in full screen with 2 other windows... CPU usage is fully maxed out.

    Both these services are flash based. Flash is a resource hog. Chrome makes that even worse by running one instance of flash per tab.

    Based on the screen shots, your CPU usage isn't anywhere near being maxed out. Also PRAM/NVRAM has nothing to do with your issues. Resetting it will not help.

    Generally speaking, Flash is notorious for consuming system resources, raising temps and decreasing battery life. For Flash-related issues:
    • Find your Flash version and make sure it's the latest version available. Never install or update Flash from a pop-up on a website. Always go to Adobe's site to get Flash or updates.
    • Install ClickToFlash (Safari), Flashblock (Firefox) or FlashBlock (Chrome) to control which Flash content plays on websites.
    • Try using the YouTube HTML5 Video Player to watch YouTube videos, when available. (May impact fullscreen viewing. See link for details.) Some have reported better performance with HTML5, while some have reported worse. Try it and find out what works best for you.

    Also, you have a lot more running than is indicated by your screen shots. Follow every step of the following instructions precisely. Do not skip any steps.
    1. Launch Activity Monitor
    2. Change "My Processes" at the top to "All Processes"
    3. Click on the "% CPU" column heading once or twice, so the arrow points downward (highest values on top).
      (If that column isn't visible, right-click on the column headings and check it, NOT "CPU Time")
    4. Click on the System Memory tab at the bottom.
    5. Take a screen shot of the entire Activity Monitor window, then scroll down to see the rest of the list, take another screen shot
    6. Post your screenshots.

    I find that Beta versions of Chrome add terrible bugs often times. Try with a release channel version of Chrome and see if it's the same.

    I'm running the same 2010 MBP with ML and use Safari. HD Flash videos play just fine although the fans start running.

    I was using the regular version beforehand, but it was still laggy.
    The audio is choppy too, not just when I'm streaming youtube or pandora, but even when I'm facetiming or playing videos via vlc.

    I think it's a hardware issue, I'm turning it into apple...
    It's funny that my phone's able to do more than my Macbook right now...

    Holy crap, ClickToFlash completely solved my Pandora/Safari problem on my rMBP!
    Every time I'm Pandora the system lags hard, and the CPU usage goes up 100%+. Using it in fullscreen bogs down the system even more, and recently it's gotten to the point of songs skipping whenever I go to mission control. Installed ClickToFlash and now I'm swiping through desktops and mission controls flawlessly! (as flawless as rMBPs can be so far..)
