7 fusion works VERY SLOW on the GM of Yosemite

Basically, Fusion 7 is unusable on GM from Yosemite as 7 fusion is so slow.

When I was still on the Mavericks 10.9.5 Fusion 7 worked just great. That's happened?

Is anyway that I can fix it? Or do I have to wait for an update?

Same thing here... registered just to comment on this issue.

I meet the same problems of poor performance, use of the core processor 1 power with VMware Fusion 7 on and off as well as Parallels Desktop 9 has the same behavior.  The problem is random, because sometimes I'll run a virtual machine in the app and it will work normally, other than that it is a used CPU and the virtual machine is extremely slow - especially if you do not keep the window in the foreground.

This question seems isolated to the iMac and final Yosemite 2011.  I had this same behavior in one of the previous public betas of Yosemite, some, it feels like an issue on the side of Apple and not one which on VMware.

Edit... Apparently this problem may be related to these particular Mac NVRAM preferences, and they say running sudo nvram boot-args = "debug = 0xd4e" should solve the problem.

  • 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.

    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.

    Trapcode particular not showing on Render but works very well in the compose window.

    Hi do not know why it does not appear in my Render.

    My computer is not trolling, everything works fine.

    My computer specs:

    I7 - 5820 k

    GTX 970

    16 ram

    Composition window:

    Render:

    Try adjusting the comp on camera Active - this is what happens for rendering. I don't know where you got this name of camera or whether it was imported from a 3D rendering, but to be sure to always have the comp set to camera activates when you're overview of your work.

    The usual troubleshooting procedure is to go to the bottom of the list of changed properties and start reset first those most suspicious. Many times it is easier if you solo the layer in question.

    The first suspicious that I see, it is the position of your transmitter would be behind a normal camera to default position:

    If I add a camera by default to a model, add a solid, add individual and then use your position parameters the particles all move out of sight of the camera

    CSS style sheet appears on the remote server when I download my Web site, but it works very well to the local server, if anyone can help I would be grateful.

    There are major problems with this page as shown in the screenshot below.

    This is caused by a liberal hijacking of APDivs (aka layers) for a main page layout.  This isn't what APDivs were intended.  That's why Adobe them removed from DW.  Unfortunately, not soon enough.

    I think you're the best option is to start over with a pre-built CSS layout that doesn't contain positioned elements.

    Either way, Flash is dead now.  Most of the people cannot display Flash media more.  You can convert the HTML5 video or use YouTube to host videos now.

  • Very slow internet connection on Win 7 on SSD, but works very well with the OS on the HARD disk and the mode safe on SSD

    Original title: network very slow connection on the current installation of Windows?

    So my situation is that I have two disks (SSD and HDD) who both have a Windows installation.

    Because this SSD is an I got free and is in used condition, I left my copy of Windows 7 intact on my mechanical failure of the SSD drive.

    Now the question is, my internet connection is very, very poor, unless I run in safe mode, or the installation on my mechanical drive.

    I use a wired connection, and our connection at home is limited to 120/10 mbit/s, while I have 5/10 at the most.

    I tried to replace the LAN drivers of my motherboard (MSI FM2-A85XA-G43) using both the driver disc that was bundled with my motherboard, Device Manager and the official site of MSI, I also checked my entire system using Malwarebytes, which detected 7 threats and were abducted, nothing helps.

    I also tried the DNS which did nothing either of hot flashes. Now notice what computer of my brother is also connected and works well.

    Now as I type this, I discovered that my speed has suddenly got stable again out of the blue, but I'm skeptical it will remain, so I still want to ask what is / was going on here.

    Thank you for your time.

    Sorry for the late response here, I've been very busy with the developments in the last days and completely focused on it.

    More than a week has passed since the problem disappeared as if by magic, and so far I don't see the signs of what is going on again.

    I think that the problem has passed away now, but if it arises again I will probably update this.

    Thanks for all the suggestions and your time in this issue.

  • 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.

  • Firefox becomes very slow with the all new Yahoo Mail

    Problems with the all-new Yahoo! Mail version: everything worked very well, but since the two latest updates of Firefox I started to notice that Yahoo was consuming a lot of CPU (it varies from 35% to 40% and is on the top list of programs CPU consumption) and the browsing experience is not so pleasant - slow. If I quit Firefox and reopen it, becomes faster, but after about 30 min slow / high CPU consumption again. Then I had to go back to the classic version of Yahoo Mail and everything works fine and consumed less CPU. Did I live it? Is it a question of Yahoo Mail? Is there a solution? (Macbook Pro early 2011 / Mac OS X 10.7.4 / Firefox 12.0) Thank you!

    Try to start Firefox in safe mode. This mode disables all extensions, customizations, hardware acceleration, etc., temporarily for the diagnosis and troubleshooting. If Firefox works fine in Safe Mode, then it is probably a problem with the add-on. Restart Firefox in normal mode, and then type "subject: addons" (without the quotes) in the address bar. Disable your extensions, restart Firefox between each one, until you find the troublemaker.

  • The display is very slow on the Satellite 1800 412

    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.

  • 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!

  • Re: Camileo S10 - very slow when the SD card is in.

    My Camileo S10 was working fine for months with my 8 GB ScanDisk Ultra II memory card.
    Now, when I start the camera, it is very slow to start and operate (a few second delay for each operations).

    When I remove the card SD and trun on the camera, it works fine.

    Is this a known issue?
    An idea for me?

    Thank you.

    Hello

    For me, it looks like a problem with the SD card inserted.
    I think you should try to format the card CD and it should check again.
    If this will not help and you won't see a performance improvement you should replace the SD card and should try another.
