• Why is the 'UNION' statement faster than 'OR' sometimes?

  Many articles say that the 'UNION' statement can make the SQL statement run faster than "GOLD" awhile. However, why is the 'UNION' statement faster than 'OR' some time? Why does CBO sometimes choose 'UNION', not 'GOLD'.

  Hello

  If you have a select statement like this

  Select * from my_table where col1 like "something %' or col2 like '% else';"

  and there is an index on col1 and an index on col2. It may be a good idea to chosse a union. This is just an example.

• Why is developer of Firefox more stable and faster than ordinary Firefox?

  So, I have some great experiences with regular Firefox. It works great themes, beautiful, good plugins, security etc., but there is one thing that bothers me in Firefox on ALL computers on EACH operating system. Whenever I have install Firefox, it is already slow, he stutters sometimes and sometimes it freezes. And this isn't just my problem because many of my friends and classmates using Chrome right now they complain about the speed of Firefox. Now, for me it is not a problem, I'm not a patient person, but it certainly is the browser that will protect my privacy rather than Chrome.

  Recently, somewhere, I saw download link saying something like "Developer Mozilla, for people like you", or something like, I installed and the man, the browser is like 10 x faster than regular Firefox AND Chrome AND Safari, I mean, this speed is outrageous! It's great, no sarcasm!

  I don't get, why is so slow regular Firefox and Firefox Developer so frickin' fast? Why? Perhaps, you can base your next update of Firefox to the developer of Firefox?

  Sincerely in love with developer of Mozilla Firefox. * muah *.

  Firefox Developer Edition is a version of Firefox. So what you see in the developer edition is coming out to regular Firefox in about 12 weeks (we releases every 6 weeks, and Dev edition is two versions before publication)

  Dev Edition also uses a fresh profile, which may be faster than your old profile which is full of old data.

• Clean install of Windows a lot faster than the preinstalled system?

  My satallite comes with windows 64-bit installed.
  Since a lot of people suggested, here and elsehwere, a clean installation making consierably faster than the pre-installed windows (all bloated and unwanted software uninstalled with the uninstall program).

  Although fresh installtion was faster without drivers and programs, it has become more or less the same after installation of all software, etc. (perhaps a difference of 2 to 4% in the use of RAM) (over 4 GB)

  Is this normal or do others go much faster on any new install, for me, this effort has proved there is not a lot of use to do a clean install to drive retail.

  Ideas, wiers and feed back?

  See you soon

  Many pre-installed utilities are required for correct functionality and it can be a headache get these functions to work after installing a street copy of Windows.

  You will find that when you install Antivirus software on a street copy of Windows, it will happen similar to the pre-installed Windows installation. So if you want that the installation of Windows pre-installed perform better, uninstall the Antivirus should do the trick.

• R7000 Nighthawk Wired is faster than the wireless

  I currently use a Nighthawk R7000 and after the speed test internet using speedtest.net, I found that a desktop computer that is connected directly with ethernet is more than 100 Mbps faster than a wireless laptop which is the only room away from the router (wired office gets 140 ~-~ 160 Mbit/s, while the laptop is ~ 30-40 ~ Mbps). Any help would be great.

  Thanks to all who tried to help, but he had a friend IT of my father who came and said: it's a certain chip (or something of the kind) in my computer that was wrong, so we got a Linksys adapter Max - Stream AC600 WiFi Micro USB. I can now get 90 Mbits/s download. Thanks again for everyone's help.

• faster than El Capitan Windows 10

  Hello

  I have a 13 "mid-2013 Macbook Air 128SSD / 8 GB/Intel i5.

  I tried the two El Capitan and Windows (via Bootcamp) 10 and Windows runs faster than Mac for a reason any.

  Launching applications faster and overall, it feels snappier and more responsive.

  How is it possible that Windows can run faster on my Macbook as the own Apple operating system?

  Systems running different programs using different device drivers. 'Feel' is a very subjective measure. My windows running in Boot Camp "feels" faster than Windows running on a Windows PC. My El Capitan "feels" faster than my Windows running in Boot Camp 10.

• Is faster than the HP Mini 110 Microsoft Surface?

  My HP Mini 110 series netbook is SLOW and it is 2 years old and the Microsoft Surface seems newer, but I want to know if the Microsoft Surface would go faster (for example, loading programs and files, etc.)

  The HP Mini 110 has an Intel Atom processor and the Microsoft Surface has an ARM processor.

  The Microsoft Surface would be faster than the HP Mini 110?

  It must be such that it is a newer CPU, but until the Surface is in the hands of consumers, we do not have really the real world benchmarks. I am 100% sure that whatever that is released by Microsoft or others would show much faster and better in all aspects. But these are marketing people making conversation, not technicians running the real numbers.

• Games run too fast! (Faster than normal around 1.5 x)

  Hey I have problems playing games since the installation of W7.

  I tried only two games, which is Half Life: counter-strike 1.6 through Steam and Batman Arkham Asylum.
  From what I see, I shoot and walk faster in CS 1.6, when I play on my own. But when I join a server on Steam, I go fast, Yes, and then I will be stuck (I guess because the server will try to match my speed with others)
  In Batman: AA, I was comparing Youtube videos with my game and found that my Batman works faster than in the videos.

  I'm also running on a map of XFX9600GTXXX, with 8 x AA and AF, with Vsync off (must be turned off to reach 100 fps in CS, which I play competition)

  Tried solutions:

  I've been Googling for answers for almost 3 days without getting anything. I tried Winthrottle to slow down my CPU, defining my affinity proc at the base, and it does not work.

  (Although the speed improved to Batman, but running it on a carrot is terrible - did not work for CS)

  Turning on vsync seems to make it acceptable, but I'll be capped at 75 FPS.

  I need 100 fps on CS, because the response of the mouse is better.

  I was restoring my nvidia, same drivers try the new Forceware, nothing helps.

  I can't reformat my HD, but only not to do so due to college.

  These Core Dual optimizers, that I read are only for the amendments, I guess, so I can't do anything to this topic and it seems to be no fix.

  If anyone knows, I would like to know what is causing this = /

  It could well be your network drivers.  Even if you later, sometimes people writing the drivers need to improve for questions like yours that described and so you should keep a watch last updated driver.  On my laptop, for example, constantly Dell publishes new drivers for it that problems are discovered and updated correctly to handle Windows 7.  While it works great, they discover problems that may affect performance.

  Have you read anything in the counter-strike forums about anyone else having a similar problem?

• Responsiveness of Windows XP is much faster than Windows 7

  According to this video

  http://www.YouTube.com/watch?v=Ay-gqx18UTM

  and MY personal experience, the xp desktop responsiveness is so much faster and less glitchy than windows 7 (e.g. open services.msc and play with the window, you will see black borders).

  You guys are going to solve this problem on Windows 8, to finally defeat xp in all aspects?

  Original title: why Microsoft, why?

  I have the same specification as Palcouk outside the video. Mine is a HD4250 integrated ATI and I get the black border.

  It may be safe to pin this one on the video card and drivers reasonbly

  Yes and also view the video uses Win 7, RTM, as in no current.

  I use two operating systems on Dells reasonably comparable...  I would say that in my experience 7 is faster than XP and not at all what I would call "glitch."

• Why disable SuperFetch on ssd, if the RAM is much faster than the ssd?

  Directed by Microsoft that SuperFetch and PreFetch must be disabled, if the OS is installed on an ssd, in accordance with article http://support.microsoft.com/kb/2727880. But SuperFetch is used for loading the data components of applications, which were very often used for RAM. Although the ssd is faster that a hard drive is not faster than the RAM. So, I do not understand why Microsoft suggest disabling this feature. The only reason why I want to understand, it's because of a limited RAM. If the RAM is sufficient beyond 6 GB, if we disable SuperFetch, then the boot time and increase the loading time of most used applications. I miss something here?

  The other question is about PreFetch. I feel, maybe wrong, it does the same thing with SuperFetch, with one major difference. It loads all the information data on the ssd or hard drive, instead of the RAM, in order to accelerate the launch of applications and time when the OS is installed on a hard drive to boot. If I'm right, let's disable the PreFetch it stores information for one ssd or hdd, while SuperFetch stores data of RAM information, which is much faster and so it must be enabled if there is a sufficient RAM.

  I look forward to reading the notice of a Microsoft software engineer.

  Hi Leventis,

  Prefetch copies frequently accessed files together into a contiguous on the disk area so that they can be located and loaded more quickly. That it takes a lot of old drives to recover data faster.

  SuperFetch predict what applications you run next and preload all the necessary data in the memory. She has also done that with startup files. And for all the three days he sends a defragmentation command to the OS drive that will cause problems in the SSD drives.

  In traditional hard drives (HDD) data are scattered throughout the disk, so that the operating system for access, it will take more time. It is suggested to perform a disk defragmentation. But storage technology is different in SSD, where, it records the data dynamically and it recovers more quickly. Who will be low down the burden on the RAM and the RAM can be used for uses such as for the opening of the games graphics high-end, etc..

  Hope this information is useful.

• Is faster than the local AIR IOS app remote SWF SWF because I can ' t use the unloading code.

  Are faster than the local SWF on AIR IOS app remote SWF because I can't use the code to unload on IOS of AIR.

  my local code:

  Stop();

  import flash.net.URLRequest;

  import flash.system.ApplicationDomain;

  import flash.system.LoaderContext;

  import flash.filesystem.File;

  import flash.filesystem.FileMode;

  import flash.filesystem.FileStream

  go_level_2.addEventListener (MouseEvent.Click, Level_2);

  function level_2(event:MouseEvent) {}

  var loader2:Loader = new Loader();

  var loaderContext2:LoaderContext = new LoaderContext (false, ApplicationDomain.currentDomain);

  var file2:File = File.applicationDirectory.resolvePath ("level2.swf");

  loader2. Load (new URLRequest (file2.url), loaderContext2);

  addChild (loader2);

  }

  Because it works for me, because I can't unload the SWF app file en becomes slow, I'll put the SWf file "s on a remote location.

  But I can't imagine what is happening when I loaded the SWF file remotely. It remains on the server, or it remains on my application when I unloaded it, and the app gets also larger. I hope you can help me because I went on the internet for a week and do not now how to go further.

  I had a similar problem, but not on iOS.

  Maybe my solution might work for you too, however.

  The problem was this line:

  new LoaderContext (false, ApplicationDomain.currentDomain);

  Do not reuse the same field of application, or you will never be able to get rid definitions and thus the SWF loaded.

  Instead, make a new child application domain for the current domain, keep track of it and it has as well as the rest of the SWF file when you are finished.

  Example:

  var loader2:Loader = new Loader();

  var appDomain2:ApplicationDomain = new ApplicationDomain (ApplicationDomain.currentDomain);

  var loaderContext2:LoaderContext = new LoaderContext (false, appDomain2);

  var file2:File = File.applicationDirectory.resolvePath ("level2.swf");

  loader2. Load (new URLRequest (file2.url), loaderContext2);

  addChild (loader2);

  Then

  function finishLevel2(event:Event):void

  {

  var loader2:Loader;

  	loader2 = Event.Target.Loader;
  	loader2.parent.removeChild (loader2);
  	loader2.unloadAndStop (); appDomain2 = null;

  }

  Note that the definitions of the classes of the loaded SWF file will be available in the new application domain.

• Why preview is rendered faster than the actual speed of my clips?

  When I create a new project, the overview of my project "plays" faster than the speed of the video. As it is fast forward. Each of the speed of clips are 100%.

  I tried to uninstall and reinstall the first but still have the same problem.

  Any idea? Thank you

• is it possible that an application on a virtual machine is faster than in its host?

  To measure the performance of our software on vmware, compare us the performance of vm compared to its host machine.

  We found that performance on three different machines showed a very different behavior, of 50% slower at 10% slower.

  And the strangest thing is that there is a single machine, his vm is faster than its host.

  Any help on the possible reasons is appreciated!

  Thank you!

  Additional information:

  The application is time CPU,.

  CentOS 6.2 for the vm and host,

  VMware Workstation 10.0.1 build-1379776

  Hardware Dell R720	VM vs host
  Xeon 2 CPU E5-2620 0 @ 2.00 GHz 12-Core, 32 GB	-50%
  Xeon 2 E5-2650 V2 2.60 GHz, 16 Core CPU, 32 GB	-10%
  Xeon 2 E5-2630 0 @ 2.30 GHz, 12 Core CPU, 64 GB	20%

  After eliminating the various factors, we finally understood the cause: hyper threading

  After that we switched off the hyper threading, everything became normal, the slower and faster virtual machines showed same performance.

  Host performance has even improved, about 10-20% faster than the virtual machine.

  Hope that this experience and this information can be useful for others in the future...

  Thanks for your help during our survey!
