Huge downturn on a very high amount of tabs

I just came across a problem which I'm not sure of is a problem with my computer, or a problem with Firefox, although not many are likely to be in. After that opening, about 650 tablets through 12 windows (not at the same time, he added to it after about a week of closing only not tabs) Firefox fell on massive slowdowns, where it was almost impossible to navigate through the tabs or windows or anything. My computer should still after that have about 2.5 to 3 gigabytes of RAM left in quality after subtracting the three and a half, that Firefox took at this time and normal system resources, so I don't think it's the lack of my computer, as well as other processes (background uTorrent and even a movie I tried to run) has worked well without noticeable slowdown. I wonder if Firefox has a soft limit of the amount of tabs that can be opened or if it was more likely to be the case of scripts of background running on slowing down Web pages (I get the same types of downturns if Flash player runs in a loop from a faulty script problem (, but none of the tabs had race flash and I was blocking the ads that might have jumped a flash ad). As soon as I stop 4-5 tabs that Firefox has returned to work as usual, so when I opened 5 new different those up to about 650 (+ / 2-4) the slowdown in the recovery.

I'm a little obsessive compulsive keeping in the stuff of arm length that I might need even if it is next week so I am likely to face this again if this is the case. If Firefox did not such a problem, tell me what I should look into fixing or beefing up on my computer, such as RAM.

If I run Firefox for a week without going out of it, it sometimes becomes very slow, but I haven't noticed any pattern to it.

I'm not aware of a limit on the number of open tabs, either simultaneously, or during a session. But you can be almost a kind of memory limit in Firefox: it is a 32-bit application, so even if you have 8 GB of RAM, I think that 3 GB is close to the upper limit that can be used.

Problems of memory by the way, I had another thought:

When you browse, Firefox updates (sessionstore.js) file with information on your tabs and windows currently open and recently opened. Depending on the activity, you are, this can happen as often as every 15 seconds. Sometimes, Firefox is facing problems now this file; It can become corrupted or inflated. If your open tabs are essential to monitor, you might want to try the functionality of bookmark all tabs (right click on a tab in the window) in the case that Firefox ever grinds complete stop or the history of session file becomes unusable.

(The session history update interval and the number of windows/tabs closed than remembered are adjustable if it seems relevant).

  • Satellite A660-167 - audio latency very high indeed

    Hello guys.

    I have a Toshiba A660-167 and I'm having a problem with the audio latency, it is actually very high.
    I am using Windows 7 Home premium 64-bit and I already tried using windows 7 32-bit and windows Xp but the problem remains.

    Toshiba already tried to "fix" my problem, but as they said that my laptop works perfectly.
    If someone knows something about the latency problem that his help will be very appreciated...

    Thanks in advance

  • Qosmio F30-140: Vista stopped and I heard a very high noise

    Hello everyone

    Really, I have a big problem
    My operating system is Windows XP media center 2005 and it is written above (Designed for windows xp, Windows Vista capable)

    2 last week I had installed windows Vista ultimate 32 bit and pilots of the Qosmio, but after 2 days when I worked in Microsoft office Word, the system stopped and I heard a very high noise of it (maybe the processor or fans) but he was really scared and immediately, I turned it of the power button.

    This problem occurred 4 times through this time. I had installed windows xp again from the recovery disk and there is no problem and I installed Windows Vista again hard night but today in the morning the same problem again.

    I don't really know how to fix this and I look forward to receiving help from you.

    Hello

    It s certainly nothing wrong with the firmware Toshiba VAP this nothing to do with your question, you issue sounds more like an overheating problem the OS freezes at a temperature inside the laptop.

    Probably don t cooling modules run a full implementation because of the dust and debris inside the laptop.

    The second reason why a laptop could overheat is the graphics driver installed _non-Toshiba_!

  • Very high CPU usage in svchost during playback of an event in a major newspaper of the events using WMI

    Hello

    I have a very high utilization of the processor in the process 'svchost.exe LocalServiceNetworkRestricted' during playback of an event in an event log in Windows 2008 64 SP02 using local or remote WMI.  The same happens using Wbemtest or C++ WMI code.  The use of WbemTest, "Open forum" (identical to one the GetObject of WMI API) read just one of recent events in the event log:

    Win32_NTLogEvent.logfile = "application", recordNumber = 2615657 (in this case, it was the id since the last event in the very large to the Application event log)

    takes 3/4 seconds consuming thant plus 50% of the monitored computer CPU.  This only occurs when the event log is very large (in my case 1 million records), the event log contains about 10000 events just fine.

    The problem is that I read the complete paper in a remote program and this product CPU usage charge too much CPU to the monitored computer.  I do not read the newspaper of the events one by one, but I'm using WQL queries but I do some GetObjects and the peformance is really terrible.

    Any idea what to change or search?

    Hello

    as I mentioned in the title line that we our office gives problem that it begin to become hunged and at this time, when I open the Task Manager to check the status of performance using Page file shows very high up to 1.5 GB.

    Please suggest!

    Thank you

    Brahmaprakash Mishra

    If the swap file itself grows in fact you may suspect a leak memory by an application, it is called a leak 'Paged', usually, notice increased use of pagefile with an increasing slowness of the machine.  As the demand for 'leaks' or consumes more memory Windows pages pages of the RAM in the swap file, where the name, 'Paged' leaking, leaks memory in the paging file.

    The Task Manager is not a very good job of giving you the 'real' swap file usage, to get use accurate, you can analyze the file with the corresponding Perfmon counter or you
    can use PageFileMon from Doug Knox utility: http://www.dougknox.com/xp/utils/xp_pagefilemon.htm

    Open your task manager and click on the view menu and click Select columns...  Put a check mark on the columns paged and Thread Count.  Keep an eye on these columns over a period of time, showing a constantly growing number likely suspicious process Thread.

    You can monitor these counters with Perfmon, that might be useful:

    Vista and Windows 7 updated drivers love then here's how update the most important.

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded:

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - device - Graphics Manager - note the brand and complete model
    your video card - double - tab of the driver - write version information. Now, click on update
    Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
    Uninstall - REBOOT it will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
    with their own software and drivers and all other main drivers that you have.

    Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
    Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
    BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
    Updates, that leaves about Windows updates but it will not install the drivers that will be generally
    older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
    get new manually if you wish.

  • SG200 - 26 [FW - 1.1.2.0]-very high response time: > 1000 ms!

    Hello

    Problem: New SG - 200 26 Smart Switch with the latest Firmware - very high response time 500-800 ms

    We have a router of EdgeMarc 4500 with 10 VPN tunnels at 10 locations of brach. SG-200 26 Smart Switch is connected to 7 servers (Terminal 2, SQL and others), all locations have 50 MB download and download 20 MB of Verizon FiOS Internet service speed.

    Depending on the tool Kulvik, the response time of this switch is around 500ms. At the same time, the response time of the EdgeMarc 4500 router is around 40ms and less.

    We have 60 remote desktop computers connected to our SQL Server database and 40 users of RDP via Remote Desktop. The configuration is the same for 3 years. But we change the switch HP 1800 - 24G of Cisco because of some failures of connection. For connection failures, we first think the old switch from HP, but it looks like problem with router EdgeMarc.

    This response time is normal? I have attached two screenshots of Switch Cisco and response time for the past 24 hours EdgeMarc router according to the tool Kulvik. Any other advice would be greatly appreciated. Thank you.

    Hello Srinath,

    Thank you for your participation in the community of support to small businesses. My name is Nico Muselle of Cisco Sofia HWC.

    The response time of the switch can be considered quite normal. Reason for this is that the switch gives CPU priority to its actual tasks that would be sure to pass, lists of access, VLANs, QoS, multicast, and DHCP snooping etc etc. As a result, the switch itself ping response time does not show in any way the good operation of the switch.

    I invite to try the rattling customers connected to the switch, you should be able to notice that the response time to customers are much lower than the response time of the switch itself.

    I hope that answers your question!

    Best regards

    What we are talking about here? LAN or internet.

    You can check your internet speed and ping on the site below--

    If you are running four servers CS I think he would have to do with your servers themselves, or even the internet / LAN connection parameters.
