Too much Delay

Hi all, I have a 4503 and some 4006s with WS-X4548-GB-RJ45 modules. I these switches I have servers connected via 1000BaseTX to the modules. The problem is that when I make backups (Gigas of info), the delay it takes is worrying and frustrating (it takes more than 10 hours to back up 30 Gigas of info)...and in theory it should not happen since they are connected at 1000Mbps....question ...should I configure something additional on every involved interface..??...I mean, queueing for example..??...Is the gigabit port underutilized..??

Few questions....What backup software are you using? What type of backup device are you using? What OS are you running? I really don't think it is a problem with the switches unless you have some speed and duplex mismatches....if you did not check the speed and duplex on the servers and the switch port...make sure they are set the same...I personally hard code the servers and switch ports.

  • Too much delay to load new SWF after unloaded the current SWF

    Hi,
    In our application we are using more than 10 SWFs. While traversing one SWF to other trying to unload currently loaded SWF and loading the new one. We were success to unload the existing SWF but the problem is, taking too much time to load new SWF (more than 5 seconds). Please suggest a useful method to avoid this delay to get better performance.
    will get some idea from following code snippet.
    Thanks
    public function SwitchSWFs():void
                   if (null != SystemAgent.getInstance().currentSWFLoader)
                                    SystemAgent.getInstance().currentSWFLoader.unload();
                                    SystemAgent.getInstance().currentSWFLoader = null;
                                    trace("HomeUI : Previous swf unloaded!!!");
                    else
                    addChild(SystemAgent.getInstance().swfLoaderSecondSWF);
                    SystemAgent.getInstance().currentSWFLoader = SystemAgent.getInstance().swfLoaderSecondSWF;
    //will invoke from a button click
    public function LoadSecondSWF():void
                    SystemAgent.getInstance().swfLoaderSecondSWF.load(new URLRequest("Second.SWF"));
                    SwitchSWFs();

    Is the delay happening when you test locally?
    One thing you might try is to load any Loaders you have up front before they are needed so that there is a better chance they are ready to be added to the display list when called for.  So instead of having the button trigger loading the swf, you just have it call the switchSWFs function.
    Another thing you might try if you keep it where the button triggers loading the file is to assign an event listener for the Loader to detect when it has finished loading and then have that listener's event handler function call the switchSWFs function.  At least that way, the current swf is not unloaded until a replacement is ready and waiting.

  • Garageband output on BT speaker? Too much latency, but iTunes plays fine

    Hi all
    I have a Creative D200 that I like to use to play iTunes music in my office.
    Today I tought that I would like to play my electric guitar, since I am basically alone and can make as much noise I want (yay).
    I am surprised to see thou, that iTunes play music without changing anything, while GarageBand does not .
    I have a USB unit that is my interface for Midi, Guitar and other instruments (an Alesis IO2), I use it to record my guitar, or to just play games like Rocksmith, or record riff with Guitar rig. The unit works fine, no latency when I use the headphones connected to the unit.
    Anyway; back to GB: I tried to play the guitar, and I can hear the iTunes music playing on the speaker, and the guitar play in my headphones connected to the IO2. I tried to change the output to D200 (the BT speaker), and I get the output, but the lag is so much that is impossible to play honestly.
    Tired to look for a function to reduce the latency but there is none on GB.
    Now, I understand that BT has too much delay, altho I don't understand why the output of anything on my computer is going trough the speaker with no latency at all (games, iTunes, system sounds), but neither GarageBand nor Guitar Rig are able to play (Guitar rig does not even give me output at all, Garageband give me the high latency). I tought that should not matter where the sound comes from, since everything is wired to the computer; so when the audio has to be sent to the bluetooth speaker, shouldn't matter if is the output of GB, GR or anything else.
    Possible that is possible to decode a MP3 on teh fly and play it with 0 latency, while is not possible to output the processed signal of a guitar, in the same way, on a mac pro with 16 GB of ram and 12 core?

    Hi Becca_hague,
    Thanks for the post.
    You will need at least 2MB to effectively run BT Vision.  The real problem here is not your speed, its your connection constantly dropping out.  If we can figure out why your connection is dropping and fix this, then your speed should recover by itself.
    Your noise margin is not very high at all which is strange, as one of the main culprits of a dropping connection is noise interference.  The fact you are already in the test socket rules out internal issues.  It may well be that the router you are using is faulty.  On the other hand this may not be the case.
    I would like to run a few checks on the network side of things, to see if anything stands out as odd.  Please drop me an email to the email address in my profile. (click on my name and you will find the address under the "about me" section). Include your BT account details and the link to this thread.

  • Taking too much time using BufferedWriter to write to a file

    Hi,
    I'm using the method extractItems() which is given below to write data to a file. This method is taking too much time to execute when the number of records in the enumeration is 10000 and above. To be precise it takes around 70 minutes. The writing pauses intermittently for 20 seconds after writing a few lines and sometimes for much more. Has somebody faced this problem before and if so what could be the problem. This is a very high priority work and it would be really helpful if someone could give me some info on this.
    Thanks in advance.

    Hi fiontan,
    Thanks a lot for the response!!!
    Yeah!! I kow it's a lotta code, but i thought it'd be more informative if the whole function was quoted.
    I'm in fact using the PrintWriter to wrap the BufferedWriter but am not using the print() method.
    Does it save any time by using the print() method??
    The place where the delay is occurring is the wile loop shown below:
                while(allitems.hasMoreElements()){
                String aRow = "";
                    XDItem item = (XDItem)allitems.nextElement();
                    for(int i =0 ; i < props.length; i++){
                         String value = item.getStringValue(props);
         if(value == null || value.equalsIgnoreCase("null"))
              value = "";
                             if(i == 0)
                                  aRow = value;
                             else
                                  aRow += ("\t" + value);
    startTime1 = System.currentTimeMillis();
    System.out.println("time here is--before-writing to buffer --out.flush() done: " +startTime1);
    bufferWrt.write(aRow.toCharArray());
    out.flush();//added by rosmon to check extra time taken for extraction//
    bufferWrt.flush();//added by rosmon to check extra time taken for extraction//
    bufferWrt.newLine();
    startTime2 = System.currentTimeMillis();
    System.out.println("time here is--after-writing to buffer : " +startTime2);
    What exactly happens is that after a few loops it just seems to sleep for around 20 seconds and then again starts off and ............it goes on till the records are done.
    Please do lemme know if you have any idea as to why this is happening !!!!! This bug is giving me the scare.
    thanks in advance

  • IPad Air too much time to open a link from Mail

    SInce the last update to iOS 8.02 my iPad Air takes too much time to open a web link from the Mail App, Safari open itself with a long delay.
    furthermore The attachments into email are often not readable, have to reload the message to be able to open the attachment.
    LAst but not least, I have too many messages not downloaded from the iMap server and I can read just the title of it.

    There's a large thread around about this Dolphin problem.
    Disabling Nepomuk in System Settings has proved to be the
    cure in many cases.

  • Here we go again! Now I am being charged too much ...

    After a recently fiasco with call charges some months ago, I am now being charged too much for my line rental.
    Specifically, I am on the Unlimited Evening and Weekend Plan, which up until my latest bill of 25/10/2011 included a £3.00 credit/discount. However, my most recent bill does not include this £3.00 credit/discount which I always get and believe I am entitled to.
    The £3.00 discount always appears on my bill in the following statement - copied from my September bill:
    "Credit: Unlimited Evening and Weekend - £ 3.00 - 24 Sep-23 Oct 11
    Plan Deal
    You get your calling plan at a special rate. We show this on your bill by
    giving you a credit of £3.00 a month
    Discount for Evening and Weekend calls with 12 month renewing contract"
    The above paragraph has been omitted from my latest bill and the £3.00 credit has not been given.
    Moderators on this forum have helped me with problems in the past, and I sincerely hope you can fix this latest problem for me too.
    Many thanks.

  • Serial port vi taking too much time to communicate?

    i am using visa vis for serial communication the read vi takes too much time to give me the bytes at serial port.what should i do to decrease the delay?

    You wouldn't happen to be specifying a byte count to read or setting read termination when a specific character is read would you? If you are, if you don't have the right number of bytes in the serial buffer or if the termination character is not seen, then VISA read will wait for the time specifed by the VISA timeout value. To fix the first problem, use the VISA Bytes at Serial Port function to determine how many bytes to read. In the second case, use a VISA property node to set Message Based Settings:Termination Character Enable to false and Serial Settingserial End Mode for Reads to none.

  • PDPageDrawContentsToWindowEx takes too much time

    We are using an Acrobat plugin that renders the PDF file to a bitmap in memory.
    We are using Acrobat Professional X. But same problems also appear on Acrobat 9.
    We have received several problematic PDF files from our customers that is causing the call that renders the image -
    PDPageDrawContentsToWindowEx() to take unreasonably long time.
    My target resolutions is 600 dpi but I couldn't wait for the call to return, after more than 6 minutes I kill the process.
    The same PDFs render in Acrobat with slight delay (flickering and repainting) but in reasonable time.
    I have written for this problem on previous occasions (Aug 5 2010). Since then further problematic samples
    show that is linked somehow with transparency being present, but not on all PDFs with transparency.
    We have a fast computer so the problem is somewhere in the PDF analysis.
    Trying to optimize the file didn't help.
    Checking with Preflight for PDF syntax issues also didn't find anything.

    I'll have to check the headers, but I KNOW that we exposed it to plugins in A9 – it was necessary since we pulled the DrawToWindow call on the Mac (carbon vs. cocoa).
    What you are asking the SDK to do is going to be painful on large complex images.  Drawing into an HDC/Window adds SIGNIFICANT overhead to our rendering process, since we have to do all the work in our own "bit buffer" and then copy that buffer into the OS's provided HDC.  OUCH!  This is why  DrawToMemory is better.
    Additionally, if you have files with complex transparency AND you want OverprintPreview, that's also going to be VERY complex rendering pipeline – made WORSE by the need to end up in an HDC.   Forgetting separations for the moment, consider that we have to convert everything to CMYK (since you can only compute OP in CMYK), blend colors, then convert all of that to RGB.   And that's assuming SIMPLE transparency.  If you have multiple blending groups, soft masks, etc. then you just raised the bar even more!
    How long does it take Acrobat to open up the PDF and render it completely to screen?   For separations, how long does it take to do a "Flatten Transparency" operation?
    UpdateRect won't help because of the OP and then transparency flattening

  • Delta Sync taking too much time on refreshing of tables

    Hi,
    I am working on Smart Service Manager 3.0. I have come across a scenario where the delta sync is taking too much time.
    It is required that if we update the stock quantity then the stock should be updated instantaneously.
    To do this we have to refresh 4 stock tables at every sync so that the updated quantity is reflected in the device.
    This is taking a lot of time (3 to 4 min) which is highly unacceptable from user perspective.
    Please could anyone suggest something so that  only those table get refreshed upon which the action is carried out.
    For eg: CTStock table should get refreshed only If i transfer a stock and get updated accordingly
    Not on any other scenario like the changing  status from accept to driving or any thing other than stocks.
    Thanks,
    Star

  • Too much Time until logon window after applying Security Configuration Wizard on DC

    Hi,
    The scenario is the following:
    Domain Controller on Windows 2012 R2
    DHCP installed on Domain Controller
    Clients: Win7, Win8
    Servers: Win2008/R2, Win2012 R2
    After applying a SCW template on a DC, the logon window takes too much time to appear (after reboot, lock or sign out).
    The seetings in the template are the following:
    Select Server Roles: All of the default options selected by SCW
    Select Client Features: All of the default options selected by SCW
    Select Administration and Other Options: All of the default options selected by SCW
    Select Additional Services: All of the default options selected by SCW
    Handling Unspecified Services: Do not change the startup mode of the service
    Network Security Roles: All of the default options selected by SCW
    Require SMB Security Features: 2 checkboxes marked
    Require LDAP Signing: the checkbox marked
    Outbound Authentication Methods: Domain Accounts
    Outbound Authentication using Domain Accounts: 2 checkboxes marked
    Inbound Authentication Methods: none of the checkboxes marked
    System Audit Policy: Audit successful activities
    The question is:
    What options(s) include/exclude from SCW template that avoid too much time logon windows takes to appear?
    Thanks in advance!

    Hi,
    Based on my research, SCW helps administrators to ensure that only those services, application capabilities, and ports required for the roles to function are available; anything not specifically needed by the roles the server holds will be disabled. These
    tasks above all consume time to implement, which causes the delay for the Windows logon screen to display.
    Therefore, as the way I see it, it is a normal behavior, and I didn’t find any option which could avoid/reduce time spent on applying settings within the SCW template.

  • Malicious or not? Message popped up: Mozilla security found (something like too much, forget exact word) activity on your computer so it will do a fast scan of system file. With OK button.

    I was looking at youtube.com, which always tells me my browser is not supported and recommends I download Firefox, but that is what I was using, so I went to Firefox to check for updates. (I think I also had freecycle.org open.) Then this message popped up in a new page: Mozilla security found (something like "too much", forget exact word) activity on your computer so it will do a fast scan of system file. There was an OK button. The page address was: http://update17.stegner.ce.ms/index.php?Q7Lhl9ShbRxGJXpkM1VLSi4ZE8H4pTedoVPySgeppM3VpC+thEspcFG7qxHgn1pdsC2h5ygPGWI3t5hXqMzL9EQaZZ3J1e3CKXgCb0Qp. I did not click OK but copied the link and closed the window which closed the internet. I have never seen this before and would like to know if it is really Mozilla or possibly something malicious. Thank you.

    Good catch. That almost certainly is an invitation to download malware.

    This usually happens if you are low on hardware requirements.  Check whether your machine confirms with the required software and hardware requirements.

  • Error message (Because a USB device was drawing too much power)

    Hi Everyone,
    Bought recently a new macbook pro 13 inch with Retina display with 120 GB flash drive.
    Connected a non-apple CD drive to my macbook and after that started receiving this message: "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
    initially I was receiving this message after I switch on my macbook but now after every 30 seconds this message pops up although I never connected anything to my macbook through its USB ports.
    Will highly appreciate for your help on how to get rid of this problem.
    Regards
    Homayun

    Try resetting the SMC
    Shut down the computer.
    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
    Release all the keys and the power button at the same time.
    Press the power button to turn on the computer. 
    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
