Scrolling is very slow in the unit. But in the Simulator, it works well


My suspicion is that your device and the Simulator are at different levels of the BONE, and a level of operating system manages some internal processing differently to the other.  In general, when scrolling is slow, it's a matter of page layout.

With this in mind and I'm not as good as others on this forum, there are two questionable things in your code.

(a) super.setFont (Values.getDefaultFont ());

Every time you paint anything in your gridManager, you ask to change the font for all what he.  Obviously if you change the font, it will all the fields to make sure they correspond to the new provision.  If you are originally a provision whenever you paint.  I'm surprised that you get anywhere with it because at the end of the layout, you probably call paint to ensure that the screen reflects the new layout.  It is I think where is your problem.

You must not change the font in the paint.

(b) setExtent (displayWidth, displayHeight);

I don't think you need to do this.  You can force the full width with a USE_ALL_WIDTH on the constructor.  But this, I'm not sure.

I'd be certain that (a) is your problem.

  • New installation of Windows 7 translates speeds very slow of the internet. Works in safe mode.

    3 weeks ago, I installed windows 7.

    For some reason, internet is super slow. I noticed right away because the download of the updates took forever. I thought it was because I need to install the NIC drivers, so I only have the first. It didn't fix it. Then, I searched and tried everything I could find online. The only thing that did work was that if I boot mode safe mode with network speed is very well .

    When I discovered that, in safe mode, everything was fine, that I started to disable any service that relates to networking. (As the Base and support Ip filtering engine, etc) This does not solve it so I decided to try the oppisite I started in safe mode with network and then loaded to the top of msconfig and any service that was not running in safe mode, I turned off. Thinking that I start one by one and find out what service was slowing downloads. When I booted in normal mode, the download speeds were still broken.

    So I continued then to disable services, I disabled all services which have to do with networking, and to enable windows.  (Things like the service that launches programs. Yes, any program that has not been opened I could not open.) Accordingly, I have concluded that it was not all services.

    This is a new installation, so I only installed firefox and flash. (no flash for the speed test) no anti-virus, etc.

    Here are a few screens of speed trials. These are actually kind of funny because the download is so fast that downloads.

    FIXED!

    So I gave up and gave my computer to my friend at home and take a look. He brought me.

    What did do? He went out and bought a new network card. I guess that despite the windows NETWORK card drivers 7 I installed windows for some reason any dislikes the network card. (NVidia nForce 10/100/1000 Mbit / s) It is built in the nice for the card mother P5N - D.

    The funny thing is that 3 1/2 weeks, when I had the problem. I asked him what he thought and he said to go out and buy a new network card. When I hesitated to do so, he said he would buy the NIC if it did not work.

    In any case, I hope this helps someone maybe who has the same problem, I did.

    recently purchased a samsung NX30 camera which came with lightroom 5, after several hours of searching on Google I got it setup properly with the right camera raw to be able to access my raw images. I found that my old laptop is very slow during the processing of hundreds of images that I usually take on a weekly basis.  I bought a new faster laptop, but when I looked for the cd with the software of series and I couldn't find in the mess of Christmas.  I downloaded a trial version of lightroom and got, it works on my new laptop. Is there a way to access the serial number of my version already installed and insert it in the version of track to make it work for me?

    Myron

    If you take the time to register to your original with Adobe installation (which most people do not), you can log in to your Adobe account and get the serial number. If you use a Windows computer and still have access to the old computer where Lightroom is installed, you can do the following:

    1. in the window folder options, make sure that you are able to see hidden folders.

    2. go to the C:\ProgramData\Adobe\Lightroom folder.

    3. use Notepad to open the file, Lightroom 5.0 Registration.lrreg

    You will be able to retrieve your serial number of this file.

  • Scrolling Web page very slow on the second monitor

    I have two monitors. When I move the window of firefox for the second monitor - scrolling of web pages is very slow. Sometimes he computer freeze (I can't move the mouse cursor).
    I checked the other applications such as MS Word, Chrome.
    This problem is only firefox problem.

    This problem apears when the part of the firefox window shows on the second monitor (or even 50 pixels)

    Hey, I had the same problem and I solved it:
    1. - in the Firefox menu, display the Tools/Options.
    2. - unselect the checkbox "use hardware acceleration when available.
    This should work better now. Apparently the hardware acceleration makes the problems only when the windows of Firefox appears in a non-primary screen (don't know why). I suppose you know, but if you want to change your primary monitor you can do it from settings (right click on the desktop, then properties).
    Good luck!

    I installed Windows XP Professional (do not use the Toshiba installation disc) and since then, the display is very slow refreshing when scrolling. It takes about 30 seconds to scroll one page down in Word for example. I tried to install the latest display driver but the installation block. Installing the driver in safe mode works but the computer hangs at startup and I needed to uninstall the driver. The laptop now seems to use a standard VGA driver of XP.

    Hello

    If you install the operating system from the original Microsoft CD you need drivers Toshiba. These drivers must be installed in the correct order. Is very important to install the driver from chipset to the first common modules and if they are available. Please also check what graphics card you have and install a good driver.

  • PR CC Pro very slow on the new custom build and lag?

    I just finished my new workstation of the construction and the first port of call was the first Pro CC installation! This version was specially designed for video editing, but I'm sad to discover that Premiere Pro is very slow and laggy. There is a lag when you click too quickly, clicking on between lag and the causes of windows (mixer audio/source/effects clip) a shift and the new window takes a second to load if you scroll down. The report is the biggest problem it will take A long TIME!

    When rendering I noticed that my CPU uses only 40 to 50%. I don't know if this is normal. If someone could help me use my material, I would be very grateful!

    Could be. Or could with this material, you need different settings.

    I have a new machine and the manufacturer has played with a lot of things... it is Variant Canyon one hell 4-core i7, primary core @ 4.6Gzh, other three to 3.5 Ghz, fsb too clocked at 166 Mhz and curiously, RAM & the three slowest nuclei have been slightly underclocked due to the way which they interface actually more quickly with these settings. By report to my previous machine, also a 4-core, it's SMOKING. On first commissioning with everything to 'standard' settings, it is faster but not Mary. At the time where he played with the settings, wowie... just kazowie note the difference in performance with changing parameters, you can re - think about the configuration of your machine. Although, of course, you can correct that there is a problem in a hardware store.

    More on the page of the Tweaker is discussed for the fsb, CPU, and frequencies RAM shook everything to get as much flow. There are things like that that can make a huge difference in performance.

    At this point, I can't emphasize too much on using the test on the page of the Tweaker to see where you machine is doing well and where it chokes... the test is a folder compressed with a file media & project plus a logging program. You extract all, install the deposit return program on your machine, import the project into PrPro with his single on the chronology of 30 seconds and run an export. The sequence specifically chose the applied effects so that every bit of material are in tatters on... CPU, RAM, GPU, fsb and disk read/write. You download the results of the logging program and to obtain an accurate statement of how perform every part of your machine. This would probably tell you more than anything else right now.

  • My wifi/internet is very slow since the IPhone Update 9.3.4.

    I have an IPhone 6 and since the update (3 days ago) my wifi/Internet is very slow.

    Minutes of need for pages to load, and the App Store and the ITunes App not to load any. Photos and videos need a time very Long if they work at all.

    The wireless router is not the problem because my laptop works fine with it.

    Thank you for responding!

    Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom.

    Alternatively, you can try to reset the App Store first, since it won't load at all. Please follow these steps:

    Close the App Store completely from the window of the selector app by double clicking the Home button and slide up the App Store preview pane until it disappears from the display. Then sign out of the iTunes Store (in the settings).

    Then restart the unit.

    Then sign into the iTunes Store and try to download again.

    (1) restart you device.

    (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

    (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth). Channels 1, 6 or 11 are recommended for 2.4 band.

    (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

    (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

    (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

    (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

    (8) backup and restore the device using iTunes. Try to restore as New first and test it. If ok try to restore the backup (the backup may be corrupted).

    https://support.Apple.com/en-us/HT201252

    (9) go to the Apple store for the evaluation of the material. The Wi - Fi chip or the antenna could be faulty.

  • Download speed very slow on the wired Ethernet connection

    I am currently getting 200 Mbps down and 0.3 MB/s on my desk wired Ethernet connection. I should get 200 down and 20 upwards.

    • On my wireless adapter on the same router, I have ~ 18 Mbit/s to the top and about 15 Mbit/s down, which seems that the wireless adapter works fine.
    • I plugged in another computer with the same cable on the same router port and got the full speed (200/20), then the problem lies within my computer.
    • I made a transfer of files to and from my computer to another computer connected to the same router and I got the full speed Gigabit times come and go.

    I searched high and wide on the internet and forums, and that many people have had the same problem I have, nothing of the multitude of solutions worked for me.

    That's what I tried without success:

    • Uninstalled the Ethernet card, deleted the drivers, forcing the new drivers to install again. No change of speed.
    • Carefully checked for Virus and malware programs (crossed the registry as well), but found nothing, and nothing has been installed recently other than windows updates.
    • The only antivirus I have is Windows Defender. I turned off and turned off the Windows Firewall, but speed did not improve.
    • I tried with IE, Chrome and Firefox, speed with different services and all tests show similar speeds. I also used FTP to a server I have, and the speeds were the same.
    • There is no other traffic devours bandwidth.

    So what I have gathered so far, it's that my Ethernet card works very slow only when downloading from the internet. Within my network, it works fine.

    What is a service that does not work well? If so who? I am not knowledgeable on the use of all services. I checked IPv4 and IPv6 and they both seem to be configured correctly, but I can't say that I am certain of what "correctly configured" is.

    These are my specs:

    HP Desktop H9 - 1215t

    Windows 7 Ultimate SP1

    32 GB OF RAM

    64 bit

    Chip Intel i7-3770

    Controller Atheros AR8161/8165 PCI - E Gigabit Ethernet (NDIS 6.20)

    I would really appreciate some help here because this problem I'm paralyzed.

    Thank you for your time,

    Tom

    By George, you got it!

    For someone who thinks he's good at Googling, I could sure use some improvements!

    The key has been the link to explanation. While I had been close to my tests, this for shows that even when you sort-of-one little-peut-be-think you know what you're doing to keep your legs unless you know EXACTLY what you are doing.

    The answer was definitely Large Send Offload, but it was a little more complicated, at least to understand what really happened. Neutralization of him gave the tour, but now I work with an active v2 and it works like a charm.

    I will detail what, in my opinion, happened here for those who may have similar problems so that they (you) may be able to figure out, as all cards are different and may require slightly different settings.

    I live in an area where so far the download speed over fast, I was able to get is 2 Mbps, on a good day, it's usually on average 1 ~ 1.5 Mbps. download speed is between 5 ~ 20 Mbit/s.

    I do a lot of video work and I constantly have to download large files on my servers. I got the computer described above about 8 months ago, and my Age (2 years) one remained on my home network.

    For a week or two, I was cursing my ISP because the internet was slower than usual and very glitch. I tested my speed and got 20 down and 0.2, repeatedly. So I went through the long and technology-challenged call representative to 'help' me, I was paying for 20/2. Only option was to wait a week for a technician to come out of my house, he stressed have shot my injurybut not before you ask me, that there are faster speeds to internet available in my place. 200/20 which is 10 times what I had, so of course I went with her. In doing so the representative asked me to Exchange my modem/router for a new handle faster speeds.

    When I replaced the modem/router, I found that the download speed went from 50/0.2 (after the new request speed but still with the old router) to 200/0.3~0.5 with the new router. I also had a Cisco E2000 router that I turned into a switch, which was also bogged down internet high speed (now that they have been much faster). But still the download speed has not really improved.

    This long and winding history is so that you (read this with a similar problem) might find the answer to your particular problem.

    Looking back when I said that the issue was in my computer because that became high speed was not quite accurate. The 'problem' was beyond my router, if the solution was in my settings with the LSO parameter. The 'problem' was not really a problem since what I see (guess) that's happened is that my ISP has been updated with equipment, and the settings on my new pc has become a problem while paradoxically not so in my old pc.

    My old pc equipped with a "Realtek PCIe GBE Family Controller" and the IPv4 LSO parameter turned on, that she was no problem under the new set of circumstances ISP. 200 / 20 Mbit/s.

    Then when I compared the setting on my new computer, it never crossed my mind that the neutralization of him would solve the problem.

    My new pc has a Atheros AR8161/8165 controller PCI-E Gigabit Ethernet (NDIS 6.20). This adapter has a setting "IPv4 LSO" more setting "IPv4 LSO v2" and "IPv6 LSO v2" décor. I don't think that my ISP uses IPv6.

    In my quest to solve the problem, I placed all of the above settings to "Enabled", without success and in my fog don't reverse these settings.

    With the 3 off, it worked fine, but I got a 5 ~ 10% improvement on the download speed with the LSO IPv4 v2 enabled and the other disabled.

    There is no way representing the service provider on the phone could know this, so calling them would not / has not solved the problem. Even waiting a week for the technician most likely would not have solved the problem as it would be measured using a laptop full download and the download speeds.

    I'm sure this will become a problem most current internet speeds that House are starting to soar (thanks Google!), so I hope this helps those who have similar problems.

    To summarize:

    Click on start->Control Panel->Device Manager->network adapters-> your adapter name (mine is Atheros AR8152/8158 PCI - E Fast Ethernet Controller (NDIS 6.20), right click and select Properties. On the advance tab, find good Large Send Offload (IPv4) and change its value to disabled , and then click on OK.

    If you have a Large Send Offload (IPv4) v2 try to set that to enable (with either a handicapped of course).

    I hope this helps!

    And thank you George.
