    Poor Youtube performance on my Z

    Does anybody know why I am getting poor performance during You Tube playback. Once the movie has fully buffered it is fine, but while it is buffering, the play back is very choppy. It doesn't really matter whether the video is HD or not. My laptop is the Z with 4gb of ram running windows XP and it has a 128gb SSD. It seems like the hard drive activity light is running all the time during play back (until the buffer is done).

    Any help or ideas would be great.

    I don't know if this will work for you. But once youtube was laggy for me, so I ran CCleaner just to see. And it actually solved it for me.

    Good luck.

    Do you have this problem only in stamina or also in speed mode?

    poor youtube performance may be linked to your video or audio drivers. try reinstalling them

    With the playback speed becoming normal again once buffering has completed, it sounds like either of:
    A: your network connection is eating up all your CPU juice.
    B: Writing to disk is eating up all your CPU juice.

    So the first question is: How are you hooked up to the internet? Ethernet, WiFi, WLAN, USB or other? And through a router, internet connection sharing or direct?

    The second question is: Does the same happen regardless of what browser you use, and whether you have turned off browser caching?

    The third question is how much free space do you have on your disk? Anything above 90% full is a very bad idea, no matter how big your HD is. The reason is that fragmentation increases exponentially as the disk approaches relatively full, and successful defragmentation becomes almost impossible, at least with the defragger that comes with the OS. Oh, you do defrag regularly, right?

    That is a good machine. You shouldn't have any problem. Others seem to be on the right track. You need to provide more info. It might be directly related to your internet connection. What kind of connection are you using? Broadband? Dial-up? Wired? Wireless?

    How long does the buffering take? Is it the same with any video you try?

    I have broadband with a wireless N router. The buffer doesn't take that long, it depends on if I do high quality. The problem is worse when the video is HD.

    I wonder if this is related to the "Enable Hardware Acceleration" option for flash movies. Right click on the movie, and don't check the "Enable Hardware Acceleration". See if that helps.

    Wait a minute. Does your SSD happen to be a OCZ or Supertalent? If so then we know the cause.

    Have you tried different browsers?

    IE/FF/Opera/Chrome
