We are having an issue that we are having trouble tracking down a solution for. Our organization uses Flash videos for training purposes. On, what appears to be, random machines the videos will play very slowly. Now here comes the unique part: They will run fine the instant a thumb drive or something similiar is put in.
Computer Setups: Windows XP SP3 using IE 7. This is something that cannot change due to hospital apps not working outside of this specific setup. 4 Gb of RAM, Dual Core 3.3 Ghz CPU's up to Quad cores, and an array of video cards have been used (ATI, Nvidia, and intel onboard.) All the setups have the current Adobe Flash versions.
Troubleshooting steps taken:
Fresh off the dvd setup of XP SP3 and current updates: Runs slowely (we also turned off hardware acceleration)
Fresh off the dvd setup of Win 7 and current updates: Runs smoothly
We have updated IE on the XP SP3 setup to IE8 and it still runs slow. We install Firefox and it runs slow. We install Chrome (which has Flash built in) and it runs smoothly. Now here's an interesting thing: If we run a video in IE it will be slow. If we then run a completely unrelated video in Chrome side by side the video in IE runs smooth until the Chrome video gets done which in turn slows the IE one down again.
On all setups we have current drivers installed and current updates. When running these videos the instant you put a thumb drive in it will speed up the video. If you take the thumb drive out the video will be slow again.
We have done some procmon and procexplorer on these and it doesn't seem to call anything on the thumb drives. If you guys have any ideas I am more then willing to try them out.
