How much slower is wireless compared to wired?
how much slower is a wireless connection compared to a wired. for like a regular desktop computer. i know its probably slower but is it going to be something thats noticeable? or like slower but not noticeable most of the time. also would using a wireless router & wireless adapter that are both 'ac' help with the speed. the distance would be going from router on ground floor, to up one floor for the computer with adapter.
thanks.
It depends on the maximum speed of the wireless/wired speed of the adapter and the router. The Gigabit Ethernet adapter with Gigabit router can reach 1 gig of file transfer speed. With internet speed, it is different story. Internet speed is dependent on the subscription of your service provider. For wireless AC network speed can reach up to 1.3 Gbps if you are using AC adapter in 5 ghz and 10 feet distance. For wireless internet speed, the download speed can reach to 200 mbps and upload to 50mbps.

Has anyone noticed how much slower it is to import photos from iphone to iphoto
has anyone noticed how much slower it is to import photos from iphone to iphoto in Mac OS.?
How many photos do you have in your iPhoto library? As your library grows, it will take more time to load when the app launches.Personally, I have not noticed any slowdown.
And my question was meant to find out whether you import process had gotten slower than...a year ago, a month ago, compared to other photo apps? Running Mountain Lion..since you upgraded? In the end..what? Hence, I asked.
Try being clearer next time. That way we don't have to beat around the bush when trying to help you. -
How much longer before wireless ThinkPad keyboard?
How much longer do we have to wait for a wireless ThinkPad keyboard?
Current ThinkPad USB keyboard with TrackPoint is ridiculously priced, considering it's on a wire, while you can buy a very decent wireless keyboard from Logitech for half the price. (I'm referring to the K340, which has quite a decent key-press experience.)
Seriously, nowadays wireless keyboards are no rocket science, nor expensive to manufacture. Lenovo totally dropped the ball here. Or maybe Lenovo thinks its Lenovo-branded wireless keyboards are reasonable competition for the ThinkPad family? Well, either way, Logitech wins.
Get your act together!
Of course I realize I'm most likely talking to a wall. After all this is the company that has just released it's a top-shelf laptop family (X220) that lacks USB 3.0. And in the past - workstations for CG artists and CAD engineers (T61p) with a TN display and a D-Sub port. Also, 16:9 displays (i.e. a ratio useful only in movies) in business laptops.
Seriously, you need to hire a new person for feature policy. Someone with common sense.I second that, third that and fouth that. Instead Lenovo seems to be heading in the opposite direction w/ the latest USB keyboard dropping the UltraNav and keeping trackpoint only.
A wireless UltraNav would be a kick butt wireless accessory which I'd buy in a flat heartbeat. Just think how useful it would be home theater setups or just in general... as I am having so many issues w/ my USB Ultranav and doc 3.
My dentist office uses a wireless setup in each patient room and they have a wirelss keyboard and mouse.. you should see them using the mouse sometimes. A wireless UltraNav is the best of both options!
If I could take the keyboard off my W510 and the fingerprint reader and integrate that into a wirelss ultranav.. then there's perfection.

How much "snappier" is 2x23" compared to 2x30" ?
Regarding speed and "overall snappi-ness" of Aperture, running on a Macpro:
Theoretically, 2 x 30" is a total of 8.192.000 pixels in max solution, where as 2 x 23 is "only" 4.608.000.
The GPU will have to deliver 78% more pixels on 2x30s.
Will a 2 x 30" system be noticeable slower than 2 x 23" when working with RAW-images in Aperture?I was given the understanding by Apple at PhotoPlus expo that you can expect a difference if both displays are hooked off one video card esp. if you process pretty big RAW's with plenty of adjustments.
One consideration is the VRAM. For 2 x monitors, given the same GPU, 512Mb is better than 256Mb, and 256Mb is better than 128Mb.
OS X doesn't support SLI, but the Apple guys suggested I try holding onto my old 6600 nVidia card and hooking one monitor off that (using it for the tools or non-imaging apps., like Safari, Word) and hang the other monitor off the new X1900. I can't test this for a couple of weeks (2nd monitor is a pressie!!!), but if I find anything out, I'll update the thread.

Why do I have to guess how much data I might use in a month when I select a plan?
When I sign up for water service, I don't guess that I might use 1,000 gallons a month, and then pay three times the going rate for water if I take a few extra showers. I get charged for how much water I use that month.
When I sign up for electricity service, I don't guess that I might use some set number of kilowatt hours, and then pay three times the going rate if we have a heat wave and I run my air conditioner for a few extra hours.
Why do I have to guess how much data I might use, and then spend three times the going rate if I stay up watching youtube videos for a few extra nights?
It is stressful to have to constantly monitor usage, and figure out ratios of how much I've used compared to how much time is left in the billing cycle to see if I need to curb my usage. It is not a good customer experience. I would prefer that data be charged a flat rate based on actual usage, perhaps with an option to throttle speeds at certain levels to prevent cases where a minor lapse in judgment could ruin my monthly budget, like forgetting to check data usage religiously on a device meant to simplify my life.
Thank you for your consideration.Simple answer is Verizon is offering a block of data for usage.
Where I live the water bill states my wife and I are being charged for 30,000 gallons per quarter/half and the price is say $60 however we never use any where near that amount. I send the meter reading in and it shows the amount we use. But the hamlet we are in has a set amount of gallons. Not fair but we live with it.
For your data outside of the unlimited which is not available any more to new customers you may be a light user and never go over the 2GB for $30 dollars a month. If you do you will pay through the nose for data. If you pay for more data say 4GB and I don't have the price for it so lets say its $70 then you don't have to watch as much for overage fees. But you are paying for the data in advance so as not go over and get hit with whopping fees.
It is just the way it is. -
Is the Core i7 processor comparable, much slower, or faster than the 2.8 Ghz core 2 duo from 2009?
I am looking to get a new MacBook Air, but when looking at the prices I am seeing the MacBook Pro 13" for the same price and a lot more guts (RAM and Processor). I am ok with spending the amount of money on the air if it means I get a computer that is like my iPad, which i love (flash based, snappy), but don't want it to be super slow.
I am coming off of a 17" 2.8Ghz MacBook Pro from 2009. I was happy with the speed and power of that machine. The most taxing thing I did was make a complilation of family movies in iMovie and burned them with iDVD once in the 2 years of ownership.
I mostly browse the internet and compose written documents, and keynote presentations.
I know my questions may seem stupid, but I don't know how significant the changes between i7 and Core 2 Duo are, so I ask the question:
I am wondering if the processing power in the core i7 will be somewhat comparable, much slower, or faster than the 2.8 Ghz Core 2 Duo I had in my 2009 computer?
Thanks for any help!!Hi brosephb,
Like you I went through a similar comparison process. I bought the MacBook air 13" and up specced the processor and memory. I don't do anything taxing enough or frequently enough to NEED the extra power of the MacBook pro.
I am overjoyed at my air. It's gorgeous, the way it wakes instantly, it's speed and it's portableness is so endearing that I just don't use my iPad anymore. I read numerous reviews on it and the overwhelming opinion was it's addictive ease of use because of it's slim, light and rapid waking. At work I can hold the air with one hand, open it rapidly at will. It's just great but it's made my iPad redundant (for me anyway).
I see the new airs are even faster and I'm tempted to consider selling my 6 month old air and getting the new one, but, it runs a dream so I am happy to just be envious of the new one.
In short, unless you need the power (for your work) go for the air. I'm looking at a new iMac to use as a home work station. For the price of a new air I can get an iMac that will swallow any task for a good few years to come. And my air will suffice as my mobile companion. However, that's just me spoiling myself as, at the moment, I have no teal need for another mac. I may get the cinema display for any long winded tasks, as the screen size will help with multiple tasking.
A bit of a ramble, hope this is useful. -
How Can I Improve Mavericks Performance (much slower than 10.8)?
When I upgraded to OS 10.9, I immediately saw a significant slower performance than with 10.8 or 10.7 (which I had been using for about two years). One big difference was a delay with the boot disc thrashing a lot when I started the computer and when I launched any app. That is, after starting my Mac Pro (2008), once the windows are all visible, there is a 30+ second delay (with the boot disc thrashing a lot) before it responds. A very similar thing happens when I launch any app. For example, when I launch iPhoto, after the photos appear, it takes 30+ seconds before it reponds to any mouse clicks. Under 10.7 and 10.8, there was about a 5 second delay (which I always thought was Faces doing its thing). This disc thrashing and delay before the app will respond happens with every app (Word, iMovie, Disc Utility, etc.) These delays never occured under 10.7 or 10.8.
A few people on the Apple Support forum suggested I run EtreCheck and remove various apps that they said could cause a problem with the OS. I removed every app they suggested, but I do not see any difference in performance. In my opinion, OS 10.9 has implemented something new that is causing my Mac Pro to run much slower.
I just ran a Safe Boot (using shift key while starting). I don't see any difference.
I would appreciate any advice.

Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|pagin|timed? ?o' | tail | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long. -

I have updated my iphone 4 to ios7 few days back, After that it becomes too much slow.all the applications take some time to open,
its touch response also became slow. .
One of my friends has also updated his iphone 4 to ios7,it is also facing the same problem.But the friend having iphone 4s is not facing any
problem with this new version.What i think iphone 4 has not too much good processor like iphone 4s & 5 to get it updated to ios7.
It destroys all the entertainment of using iphone.
How to update it again to ios6.
iphone 4 users please dont update iphone 4 to ios7.pleaseSorry, but Apple does not provide a downgrade path for iOS.
Because downgrading is unsupported by Apple we cannot discuss it on these forums, but you can use Google to find information on how to install an older version of iOS on any device.
Note that you will void the warranty and loose official support by Apple.
Feel free to let Apple know at http://www.apple.com/feedback
Anyway, give a try resetting all your settings:

i'm on a prepaid plan for the 4s, i want the hotspot option which isn't offered on the prepaid plan. heard the connection is too slow on the 4s only worth it on the 5 or 5s. would you agree? not sure how much the hotspot would increase my monthly bill....
To use the hotspot for any of those devices, I believe you have to switch to a postpaid account and plan. You can see the pricing for the available postpaid plans under the "Shop" area of the website.

Is it possible to upgrade Oct 2013 MBP-r SSD how much before it slows down?
Hi all,
I was just wondering if its possible for Apple to upgrade the SSD in my macbook pro retina oct 2013 model,
I sorely wish that I had gone for the 256GB model really, I purchased applecare, so I don't want to void my warranty - besides, googling around I found out that there are no aftermarket upgrades available for it anyways.
I have set time machine backup to backup manually (is this okay?, I Don't tend to make mistakes of emptying unwanted stuff in the trash, or is it likely ill need to use it for more than this?)
Also, coming from PC's ive always noticed a considerable drop in performance once a drive starts getting alot of data, how much roughly does it take to slow down an SSD, is it the same as a spinny drive? Im still pretty new to OS X, first mac and first SSD and im panicking ive made a serious mistake purchasing such a small drive.
Thanks alot for your patience, I did have a search but im not brilliant at searching lol

How much can too many imports slow inititialization down?
How much can too many imports slow applet inititialization down?
I have seen our company's sorce code for some huge applets they have written. In many, many cases, the imports at the beginning of each file are written something like this...
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.border.*;
import javax.swing.event.*;Only certain portion of these imports are actually used. Does this sort of thing really impact the applets loading speed? I know it will obviously take at least a little longer but will the user even notice?You are not actually importing the classes, but rather making the names of the classes available.

Hi
I am going to be buying a macbook air 2012 model with 4 GB ram soon. I was wondering how much space (memory) does Norton AV take up and does it drastically slow down the computer. Also, I am going off to uni so will predominantly be using the laptop for surfing and MS office.
Thanks a lotSorry to disagree mende1. In this age of email attachments and social networks, it is actually a good idea to have a good antivirus on your system. {I realize that this is a religious argument and I will say no more}. With that said, the general concensus is that Norton AV is terrible. It is intrusive and uses up a lot of cycles.
There are a lot of better AV clients out there. I use ClamXav which is free and uses the clamav antivirus that is open source. -
Why is my iPhone4 so much slower than my iPad2 on my home wireless network?
I have installed a new Linksys 3200 wireless router. And, I find that my iPhone4 is MUCH slower on the wi-fi network than my iPad2. I expected it to me slower, but not this much! Here are the speedtest results:
iPhone4 - Ping at 399 ms, Download speed at .73 Mbps, Upload speed at 1.00 Mbps
iPad2 - Ping at 84 ms, Download at 5.63 Mbps, Upload at .91 Mbps
My cable modem is supposed to be rated at 5/1 (Download/Upload), so it seems that the iPad is maximizing the use.
I've tried a complete shutdown and restart (modem first, then router, then computer). And, it seems a little faster, but not much.
Is there something wrong with the iPhone? I don't remember it being so slow before...and it seems faster on my office network!
Suggestions, please.
RobertP.S. It also seems to lose the connection from my iPhone4 pretty easily. I have to go back to settings and reset the wireless network. (Don't have to on the iPad).

My 2nd generation Airport Extreme very slow via wireless (5 and belows mbps) wired over 20. Please help! What could it be?
It is very possible that you may have some form of Wi-Fi interference nearby that is preventing your AEBSn from providing a clean RF signal on the 2.4 GHz band.
I suggest you perform a simple site survey, using utilities like iStumbler, or AirRadar to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible.
