O16.1int on top of 2.6.0-test3-mm1 is an improvement over O15int but it still has some issues. Sound skips and general unresponsiveness occur under relatively light load. For example, scrolling a PDF in acrobat sometimes results in 2-3 second skips in sound. Also, the PDF continues to scroll long after I have left the scroll button. While scrolling, if I try to switch to Firebird or some other relatively heavy app, there is a noticeable delay before it comes up. Sometimes even an xterm running mutt takes a second to show while a PDF is scrolling.
I was doing a `make htmldocs` while scrolling the pdf. That is all. In O15int, the same behaviour would occur even if there was _nothing_ else running (except the browser window and xmms ofcourse). That is the only improvement I have noticed.
I am attaching some numbers that were requested (vmstat, top and readprofile outputs). These are generated from a script that was posted here a few days ago. I am attaching the script so it is clear what was done.
While this script was running, I was basically scrolling a PDF and one long skip in sound was heard while doing so. I also kept switching between application windows.
Hope this helps.
