    Hi,

    We've never seen nothing like this.
    With "LS stock quotes" are you referring to our StockListDemo? Did you change it?
    On which IE version does it happen? Do you have any addons/toolbars on your IE?

    Angry help me, CPU of client too high

    yes, I used "StockListDemo"
    I tested on client with info
    Windows 2003
    IE 7
    No toolbar or addon

    -------------------------
    I modified StockListDemo (C# 2005) => remove class ExternalFeedProducer (cause if each small class that create 1 connection to database or read file => use more resource of server, so I keep only ExternalFeedProducer )
    and set main loop in class ExternalFeedSimulator

    ExternalFeedSimulator => 2 threads
    1 thread GetData => select data from database => add to queue
    1 thread Run => main loop => wait item in queue => objListener.OnEvent ...

    When I closed IE,it suspend long time like the first time I load page
    maybe the connection to database in progress?
    When close IE, Unsubscribe event occurs ?
    have a other way to reduce CPU usage in client?

    thanks a lot!

    maybe I about to find the solution.
    if I subcribe only 5 items, time to load first time and close IE very fast
    if I subcribe 200 items, time to load first time and close IE very long >> suspend
    Could you show me how config to update only 5 items per interval ?
    thanks

    Hello,

    Could you show me how config to update only 5 items per interval ?
    What do you mean? Do you want to filter the updates (e.g. frequency filter)?
