Why number becomes slow when after formatting function is used?

When changing something at Numbers (table, font, colors, etc), it becomes slower. I don't understant why, as the PC is brand new...

Hi Nano,
How large is the table that you are formatting? Is there a way to separate your results (with formatting) in a small table *away* from your main data table?
Regards,
Ian.

Why is Virtualbox slow when my processor isn't used at 50% ? [Netbook]

Hello everyone,
I have installed virtualbox on my Arch Linux machine, an Asus 1215N with Atom D525 Dual Core (no virtualization support), with 2GB of ram and an Nvidia Optimus (I thinks this will talk to all...), and for my school works (that require working with Ubuntu just to show that we know, and Windows for XNA and Visual Studio).
I know my pc is not a war machine, and virtualization isn't a good idea at all... but I excepted Virtualbox at least to try to use all my Hardware so I can emulate something like Ubuntu or Windows 7/XP smoothely enough to not hit my head into a wall...
But the problem is, that when trying Ubuntu (on the picture below, Ubuntu Live CD after installing), it turns out to be extremely slow when moving the mouse, opening a window etc... At start I thaught it was because of my Intel, so I opened virtualbox using optirun (for those don't having the same problem as "we" Optimus users, after installing bumblebee this is a way to .. partially use the nvidia... just enough for some games), and start using my Nvidia (with the 3D acceleration option on) with Ubuntu, nothing to do, it was slow ! (PS : Ubuntu starts with Unity-2D in the LiveCD.. for me at least).
I was excepting that when opening the system monitor he showes me my CPU being fully used, but it was not the case... as an example, at this moment when writing this post I am running the Virtual Machine with Ubuntu 11.10 in background and some other stuffs and my PC is as fast as normal....
So my question is (and sorry for the long post :S...) :
Is this (the speed problem) a problem with Ubuntu, Virtualbox or simply my computer ? And if is the 3º then why Virtualbox just don't use the maximum resources ?...
PSS : I have allocated 768mb de ram for Ubuntu (I think it is enough), and I have allocated 128mb GPU Memory and activated the 3D function..
EDIT : I forgot the picture sorry :S
Thank you in advance reading and answering,
Luis Da Costa

Are you saying that your school classes somehow depend on Unity or the apps that come with full-blown Ubuntu? Well... that's rather bad.
No they don't use Unity, they just want us to use Ubuntu, because of 1 - Gnome, and 2 - Ubuntu... nothing more , some configurations etc... just for us to show that we know how to use Linux... But because they had a problem with their PC's I was trying to put Ubuntu on a VM on my netbook to not waste 1hour finding one that was working every week, just that ^^

I don't think there are (theoretically) any problems with 64bit kernels and Bumblebee. I had Bumblebee running on 64bit Fedora 16, but for some odd reason when I switched to Arch on that machine, Bumblebee died and I eventually gave up trying to get it working.
I've looked at the Bumblebee package in the aur, now there is only 4 packages to installe that are not present in the "Official Repositories", just don't know the diference in performance between gcc(x64) and gcc(multilib) needed to run 32bits apps with Bumblebee... But since this anouncement I am pretty confiant that Optimus working natively in Linux (even with just the Nouveau drivers), it now just a question of Months... not years ^^.
So I will try, maybe today or tomorow to install de Arch Linux x64 ^^

KVM ? I found this on the Arch Wiki :
As with Xen's full virtualization, in order for KVM to work, you must have a processor that supports Intel's VT-x extensions or AMD's AMD-V extensions.
Is this the same thing :S ? Have you ever had any expierence with qemu ? I always wanted to know if it was faster than Virtualbox...
You're right, KVM needs hardware virtualization to work. I only saw benchmarks of VBox vs QEmu vs Xen when HW virtualization was available, so I don't think they are of any relevance (QEmu+KVM was slightly faster than the competition in most of the tests though). You might give it a try though, I'm quite curious about this myself:)
Phoronix: Xen vs. KVM vs. VirtualBox
The tests are awesome, I've heard that with KVM the VM is close to native speed, but that close it's just impresive !... Bad that I don't have any KVM-capable CPU... The real problem with QEmu, as I seen in the link you send me (last page if I remember right) is that there is no good 3D support for VM as in Virtualbox... I've also tried to download vmware player, just to take a look, but the only version available in the Officiel Repositories is the OpenSource one... and I don't find any information explaining how it works :S:..

Why yahoo/gmail retrieval and facebook app so so slow when in WIFI. But using the internet to check for emails and facebook is fast using the same WIFI connection??

Why yahoo/gmail retrieval and facebook app so so slow when in WIFI. But using the internet to check for emails and facebook is fast using the same WIFI connection??

Hi SandyS_VZW,
Yes tried resetting the wifi connection and problem still persist.
Here it is...to make it clear. Connected thru the same wifi at home...
-> emails (yahoo/gmail) and facebook WEBSITES are working fine and fast when using/accessing thru a browser (chrome/samsung browser) - no problem with this.
-> emails (yahoo/gmail) and facebook APP is soooooo sloooww (thru the App). Slow I mean comparing it to using their browser/websites... news feeds/emails refreshing so quickly but not when using the APP installed in Samsung Galaxy Note 4. Slow like - It will take around 5-10minutes just to get your emails and news feed refreshed.
THIS HAPPENS ONLY WHEN CONNECTED THRU A WIFI which has a speed of 10-20mb. It is not happening when connected to the network data/plan.
My wife has the same Samsung Galaxy Note 4 (coming from different provider at&t) - same setup (emails, fb app), same wifi connection, but she's not experiencing anything like it.
Not sure why, I dont want to believe that while connected to a WIFI, Verizon is restricting anything and ******* me off to make me switch to my data plan connection everytime - which is Unfair!
Was there a known issue similar about this case?
thanks,

Satellite 1410 - slow even after formating

My computer became really slow (I cannot watch videos), so I thought I had a virus and I scanned my pc.
He found a virus called "fast.exe", I deleted this file but I still had some problems, so I decided to format the pc using the recovery disks but my pc is still slow.
Does the formating made by the recovery disks delete everything or just crush the system ?
Some people adviced me to make a low level formating but I don't know how to do it and I have always thought it was quite dangerous.
What should I do ?

Hi,
As far as I know if you reinstall your OS with Recovery CD, there is no low level formatting. All your data will be deleted. Every time before you want to reinstall OS back-up your data. If you have second partition you can save it there.
Dont worry. Install your OS again. Also try to install SP2 to be sure that your Notebook is up to date.
Lot of factors can be responsible when your Notebook works slowly. You can also disable all processes that you do not need. You can find them in System Configuration Utility (Start>Run>enter msconfig and OK). Under Startup you can disable all programs that you do not need.
I have also bad experience with speed of my machine. After installation of Antivirus Software, my Notebook was very slowly. Without this Software machine was fast again.
Back-up your data and try to find out what is problem with your Satellite.
Bye

My HP dv6 1030us laptop becomes slow when removed from AC power

Hi,
My HP DV6 laptop has windows 7 operating system and it behaves pretty weirdly .
It becomes really slow when removed from AC Power and have to restart my system to bring it to normal speed don't know why its behaving like that and help to resolve the problem would be greatly appreciated and also my system gets overheated a lot and I have to use a cooling pad always to keep it cool and running properly along with AC power
I would greatly appreciate any advice in resolving these issues.
Thanks in advance.

for how long have you had this laptop... If you had it for longer than a year you may be dealing with a dust bunny (acumulation of dust in the vent that's right beside the fan). Normally when that vent is clogged you get the type of overhetaing you may be experiencing, so i recomend you to open it up and give it a nice clean as soon as you can. As for your computer slowing down without the ac adapter.
Do you know under what power option are you running ur computer?

Game performance becomes slow when unplugged

i have an hp dv5 1006 ax
with ati mobility radeon hd 3400
my games run smooth when plugged in but once unplugged it becomes slow and jerky
i tried setting the power options . it didnt help
any alternatives.. pls help

this is caused from your power settings utilizing your switchable graphics. go in your power settings and you can set it to not do that but then your battery will die faster.

HT1338 network become slow when using bluetooth.

I am using macbook pro retina display, my issue is, every time I turn my bluetooth on, the network become slow. anyone facing a same problem?

A lot of people were experiencing the same thing and reported it on the MacBook Pro forum. But that was when the rMBP first came out and I thought that the issue had been resolved with software/firmware(?) updates.
Are you running the very latest build of 10.8.2? With the supplemental updates as well?

Why is quicktime slower when using multiple mdat atoms

Hi,
I've been trying to generate a mov file and I noticed that the more mdat atoms I put in my mov file the more the file takes time to load on QuickTime, iTunes.
Even worst, on the iPhone the file takes more than 3 minutes to load.
If there are too many mdat atoms quicktime even says that the file is invalid ( error -2004 or -2002, I don't remember exactly).
Why is quicktime/iTunes slower when using multiple mdat atoms ?
Thanks,

Yeah! Problem solved: It's a QT issue.
Cause: Mac Update Software downloaded a faulty QT.
Solution: Download QT from Apple's QT site.
Great to have the Video back

Why has my Ipad become slow when loading Keynote presentations?

I use Keynote on Ipad as a presentation tool. Recently, the Ipad has been slow to load a presentation (up to 3 seconds after selecting a particular presentation). It also randomly updates presentations that haven't been used recently. Any thoughts?

Restore iPad to Factory Default; do not restore from backup. It may be the cause of the problem.

My Macbook Pro running slow even after format

Hello guys, I've had this problem with my 2009 unibody 13" Macbook Pro for at least a month. Last month I tried to reinstall OSX Lion which i previously had, but the install failed for saveral attemps (probably for my slow internet). I finally managed to get OSX Lion on and it was increadibly slow even no programs are installed so I reinstalled it again and again but the same problem still comes up. So i went to an Apple Store (Thailand) and the apple guy assisted me by trying harddisk permission repair, reinstalling the os again, none worked, i still get a super slow computer. So I went home and downgraded the os to snow leopard, it seemed to work just fine at first but after i install several (4-5) basic applications, it started to get slow again (still faster than when it was lion). Whenever i open two or three applications at once or even browsing a webpage alone i get the spinning rainbow cursor. Somebody told me its probably the harddrive, who do u think? please help - thanks.

Yes it is your hard drive.
Backup your files off the machine and before you reinstall OS X again, this time use the 10.6 disk > Disk Utility > Erase with Security Option > Zero All Data, make sure your ENTIRE hard drive is slected on the left.
Let that complete and install 10.6, then update to 10.6.8, that should be the fastest OS X version for that machine.
If you go to 10.7, it's going to slow down a little bit again.
If you can't complete the Zero erase (it takes some time to finish) after trying 2x and or still having problems after that, then the drive is causing the defective sectors and needs to be replaced.
Keep your boot drive below 50% filled for maximum performance, but never more than 80% filled.

Satellite A505D-S6958 why windows booting slow when installed new windows updates

Good day,
My laptop boots slow than usual after installing windows update why is it so? i restored it to previous setting then it boots a little faster.

Satellite A505D-S6958
The way to handle this is to install each update - on at a time - and check the boot each time.
Once you identify the culprit, we can proceed.
Microsoft offers free support for troubles with Windows updates, but we must need to know which one.

Curent version of OS 10.6.8 is running very slow. After formating, how do i reinstall this version as it was upgraded online hence no dvd available.

curent version of OS 10.6.8 is running very slow.
Two actions i can think of-
1. upgrade to lion, which should over write previous software and the reasons for it being slow.
2. Format the hard disc and reinstall snow leopard. Now how do i reinstall snow leopard as it was an online purchased upgrade from leopard.
what is the better aproach- lion or reinstalling snow leopard if that is possible.

No, you don't want to upgrade over a buggy system, Lion has issues of it's own that will only complicate matters, plus Lion is slower than Snow Leopard.
Learn all the pitfalls before you upgrade to Lion, like all your Rosetta/older programs will no longer work and more.
Leave Lion for a new hardware purchase is my advice, it's still got plenty of security and other issues.
For your performance, your likely better off replacing the hard drive with a 7,200 RPM model and maxing the RAM, download the free MacTracker to find out your specs, and OtherWorld Computing is good for videos, tools and parts.

2. Format the hard disc and reinstall snow leopard.
That will work, provided your data is off the machine first.
Now how do i reinstall snow leopard as it was an online purchased upgrade from leopard.
The 10.6 Snow Leopard disk that you upgraded 10.5 Leopard from actually has the full OS X 10.6 on it.
All you have to do is stick the disk in and hold the c key down while booting, use Disk Utility to erase the entire drive, quit and install 10.6.
Of course your not going to get the free iLife that came with the 10.5 grey disks, see if you can first install 10.5 with the same methods, then setup with the same user name as before, then upgrade to 10.6
I think Apple nulled booting off the 10.5 disks, but it won't hurt to try.
Another method would be to install 10.6 fresh by itself, then use the program called Pacifist to extract iLife from the 10.5 disks.

Slow boot after format on GS70 Stealth Pro

Hi,
i reinstalled Windows 8.1 and now the boot time is notoriulsy longer, from almost instantaneously to 5-6 seconds. I know isn't too long, but annoyed me coming from 1-2 seconds.
Fast Boot is activated in Bios and same for fast startup in Windows...
All drivers, SCM and firmwares are updated.
Any ideas?
thx
GS70 Stealth Pro
2x128gb ssd Raid from Factory.

actually fast boot is not cache system but windows 8/8.1 has support for fast boot which means it doesent take long to load but if laptop powers it self off after a while when it has been in sleep mode then it goes into mode where it cache your data in RAM or something so when you power laptop back on it will say Please wait. or Resuming Windows. thats when cache system was used but if you power laptop 100% off then it does not cache anything.
