Speed up 3g with 4os

Perform a “hard reset”,
Hold down the sleep/wake and home buttons simultaneously for roughly 15-20 seconds, until the screen powers off then an Apple logo appears, which signifies a reboot. Some users have (oddly enough) reported that performing two hard resets resolves the slowness issue.
Restore Again,
That what I think, restoring an iPhone may fix slowness but this time don't restore from backup. I knw it will will delete contacts and other data but may resolve this issue.
Give More Space,
You may leave 10% free space for your iPhone as iOS 4.x need a lot of space to perform faster.
Turn off Spotlight,
Already told you that Spotlight Search may solve this issue, follow the step by step guide posted here to turn of spotlight search. It's simple and easy, "Settings" >> "General" >> "Home Button" >> "Spotlight Search", Now switch off all of them.
if that doesn't work, you can buy a new phone at near full retail, and an insane upgrade fee to att&t to kick you when you're down to boot, or wait out your service agreement contract because att&t would rather torture you then extend your contract for some insanely odd business reason.
remember the good old days when stuff just worked (apples motto), was meant to last for years, and was made by someone with care in a factory in your country. apple 2 still works fine... 6 month old iphone, not so much. {{{ GONG }}}
hope that helps someone... i'm hoping it helps me....

Internet speed is slow with Mountain Lion 10.8.2

Internet speed is slow with Mountain Lion 10.8.2, but booting in separate drive running 10.6 is fine. Tried renewing DHCP, zapped the PRAM, ran disk utilities, and sudo chron. No change. I am running 2008 Mac Pro, 8 gig ram, AT&T DSL via ethernet. Getting 0.15Mbps instead of 3Mbps.

Did you try creating a new location and deleting the old one? Just renewing the DCHP on its own may not be enough. Follow all the instructions here, first:

If that doesn't work, have a look at my further instructions here:

Compressor encoded speed change clip with echo as motorboat sound

Took me two days to troubleshoot, through trial and error and process of elimination, why Compressor encoded an audio clip that had been speed changed and echo applied to it -- as rapid MOTORBOAT sound! Project is a 5.1 mix. Since STP3 won’t accept speed change clips, after I completed mix in STP I placed speed changed clips on FCP timeline below the exported STP 5.1 mix with the FCP audio tracks for that clip assigned to channels 1 & 2 for the fronts and channels 5 & 6 for the rears. The clip on 5 & 6 was duplicated and identical in every way to the clip on channels 1 & 2. Only the dupe clip on 5 & 6 did Compressor encode as motorboat. The identical clip on 1 & 2 encoded correctly. Both clips were set to play at same time since I wanted the effect to be on fronts and rears simultaneously. I could not get the motorboat sound to play back from either FCP timeline or Compressor preview window. Only after encode and burn to DVD did it show up. Why would Compressor introduce such artifacts on one of the clips and not both – if it’s going to do it at all – which it shouldn’t? Any ideas? I have other such effects throughout the project where I duped a speed changed clip with an effect applied to it and set it to play on fronts and rears simultaneously and Compressor encoded those correctly.

Well, it's a little late, but this is one of the reasons to have your startup drive cloned so you can restore it to a working state if an update, upgrade or install sends things south.

Have you tried resetting your fcp preferences

If this doesn't fix the problem, you could try sending the shot to motion. You could aslo try changing the speed in the motion tab of the viewer.

Problem with the wireless speed on windows with bootcamp

I've got a problem with the following:
the wireless card of my mac pro is very slow when i run windows on my mac pro with bootcamp
When i just run OSX everything works fine, but in windows, when I connect to the wireless my wireless speed
drops to 11-18mbs.
First I thought that it was a drivers issue, but after the update of bootcamp drivers 1.4 the problem still exist.
First I had a Topcom wireless router now I've bought a Apple Airport Extreme, but the problem isn't solved yet...
The router isn't 2 meters away from my mac.
And the wireless speed is fine when i connect with my dads windows laptop...
Does anyone has a solution? using a cable isnt a solution for me because in September I will move with my mac pro one floor down.

You might want to ask this in the Boot Camp forums. As your wireless work fine under Mac OS X it sounds to be a software issue as opposed to a hardware one which means as Windows users they'll better be able to help.

Firefox used to download with Speed download along with other browsers, but since updating to version 6.0.2 it no longer does so; OS Z 10.6.8 and Speed Download v 5.2.28; what do I need to adjust and how, to get it working 'in the team' again, please?

I have had problems with Safari and OS 10.6.8 (I think caused by Apple getting ready for Lion!) but after a lot of uninstalling etc I now have Safari, Camino and Chrome (all most recent versions) automatically sending downloads to Speed Download.
Speed Download Plugin v 2.1.5 is installed; I do not know what or where to adjust or reset to get Firefox letting its downloads be picked up automatically once again like the other three browsers.

Lightning is a problem for you because it hooks into Thunderbird at a low level and you need a version compiled for the platform Thunderbird is running on. So you can't do the preferred solution, which is to put your whole profile in a shared folder and have both instances of Thunderbird reference the same profile. (Ditto for Enigmail). Lightning may become an integral part of Thunderbird in an upcoming release, at which point this limitation due to Lightning should disappear.
And if you can't use a shared profile, you can't set your Lightning, or your Address Book, to share a common set of files. Put another way, the linkage from Thunderbird to its address book files and calendar data is hard-coded, and not exposed where we can adjust it. :-(
The halfway house is to place your mail stores in a shared place, and use the Local Directory setting in each account's settings to connect to it. They don't need to be in the profile; what's more important in your case is that they are in a folder accessible to both operating systems.
Look in your profile; everything under Mail and ImapMail needs to be moved out to a shared folder. Note the entries in Thunderbird under Local Directory before you do this, and reconstruct those pathnames in Thunderbird, but adjusted to suit their new locations.
(You can see here that you need to make many adjustments, one per account, in each instance of Thunderbird, so it's a high-maintenance solution and this is why we don't recommend it when the alternative, moving the whole profile, is possible.)
I share address books and calendars between Thunderbirds on various computers (and my phone and tablet) by syncing to something in the cloud; Google Contacts and Google Calendar are my choices, using gContactSync and CalDav.
Having made the break myself some years ago, I'd recommend you break away from Windows. ;-)

Why is the internet speeds so slow with mountain lion?

I have noticed an significant reduction in Internet speeds since I purchased my new Mac Mini. Same internet connection, more memory (8GB), nice new 27" Thunderbolt display but my Dell laptop handles streaming video (YouTube) much better. Even my iTunes do not run well. Significant pauses on many songs from iCloud.
I have not chnaged the default settings and I have tried Safari and Chrome browers with no noticiable differences. Any suggestions?

That worked. Thanks.

Best practices for speeding up Mail with large numbers of mail?

I have over 100,000 mails going back about 7 years in multiple accounts in dozens of folders using up nearly 3GB of disk space.
Things are starting to drag - particularly when it comes to opening folders.
I suspect the main problem is having large numbers of mails in those folders that are the slowest - like maybe a few thousand at a time or more.
What are some best practices for dealing with very large amounts of mails?
Are smart mailboxes faster to deal with? I would think they would be slower because the original emails would tend to not get filed as often, leading to even larger mailboxes. And the search time takes a lot, doesn't it?
Are there utilities for auto-filing messages in large mailboxes to, say, divide them up by month to make the mailboxes smaller? Would that speed things up?
Or what about moving older messages out of mail to a database where they are still searchable but not weighing down on Mail itself?
Suggestions are welcome!
Thanks!

Smart mailboxes obviously cannot be any faster than real mailboxes, and storing large amounts of mail in a single mailbox is calling for trouble. Rather than organizing mail in mailboxes by month, however, what I like to do is organize it by year, with subfolders by topic for each year. You may also want to take a look at the following article:
http://www.hawkwings.net/2006/08/21/can-mailapp-cope-with-heavy-loads/
That said, it could be that you need to re-create the index, which you can do as follows:
1. Quit Mail if it’s running.
2. In the Finder, go to ~/Library/Mail/. Make a backup copy of this folder, just in case something goes wrong, e.g. by dragging it to the Desktop while holding the Option (Alt) key down. This is where all your mail is stored.
3. Locate Envelope Index and move it to the Trash. If you see an Envelope Index-journal file there, delete it as well.
4. Move any “IMAP-”, “Mac-”, or “Exchange-” account folders to the Trash. Note that you can do this with IMAP-type accounts because they store mail on the server and Mail can easily re-create them. DON’T trash any “POP-” account folders, as that would cause all mail stored there to be lost.
5. Open Mail. It will tell you that your mail needs to be “imported”. Click Continue and Mail will proceed to re-create Envelope Index -- Mail says it’s “importing”, but it just re-creates the index if the mailboxes are already in Mail 2.x format.
6. As a side effect of having removed the IMAP account folders, those accounts may be in an “offline” state now. Do Mailbox > Go Online to bring them back online.
Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder, i.e. ~/Library is the Library folder within the user’s home folder.

Pushing the limits of continuous high-speed DAQ + processing, with PXI-6115 + PXI-8360

Hi all,
I'm trying to do continuous high-speed data acquisition + processing. I currently have:
Chassis: PXI-1042Q
AI card: PXI-6115 (x2)
Link: PXI-8360
PC CPU: Intel Xeon W3503 (dual-core, 2.40 GHz)
RAM: 4 GB
The idea is to continuously grab 8 channels' worth of analog inputs, scan for "events", and if found, log the events to disk.
My client would like to use the maximum sample rate of 10 MHz, but I found that above 5 MHz, DAQmx Read.vi can no longer keep up (e.g. at 6 MHz, it takes 110 ms to read 100 ms' worth of data).
Im thinking of getting beefier components, but I'm not sure where the bottleneck is. Here are some thoughts:
1) The MXI Express link
The PXI-8360 is rated for a sustained throughput of 100 MB/s.
I'm not sure how big the data is. PXI-6115's ADC is 12-bit. Does that mean each datum transferred through the MXI cable is 1.5 bytes? Is the data padded? Or is it 8 bytes per datum, because Dbls are being transferred?
2) The CPU
In Resource Monitor, I notice that the CPU usage is 0% at 60 kHz, 8% at 61 kHz, and 50% at 70 kHz (meaning that one core is maxed out). I'm surprised that it keeps up all the way until 5 MHz though.
What causes this high CPU usage? Is it due to the conversion of the data into 1D array of waveforms?
3) Something else?
Have I missed something completely? Is what I'm describing even possible?
Thanks in advance for any advice!

Hello,
Each sample will take up 2 bytes, 12 bits data + 4 empty bits. so the PXI-PCI 8360 is only able to transfer a maximum of 50S/s in this case.
Also, because the PXI bus is shared among all of the cards, two PXI 6115 cards will be trying to transfer 80MS/s or 160MB/s.
Finally, since the PXI 6115 are DAQ family cards, their specifications aren't really written for continuous data acquisition at the upper end of their sample rate, but I'm interested to know if you can get up to 10MS/s with only one card operating at a time?

Speed testing proceed with caution??

I've been fascinated by the various reports of variable speeds being seen on various different speed testing sites, so I've been having a play, and the results have been, shall we say, interesting.
Let's start at the top. No matter which machine I access it from, http://www.speedtester.bt.com/ shows me 56megs down and 12.89 up, with a max achievable of 60.1/20.
Namesco's ( http://www.speedtest.bbmax.co.uk/ ) shows 33623/14734 on my "work" partition, but if I reboot into another partition which is set up for webcasting, it, too reports the full 56megs down and 14/15 up. Same connection, same wires, barely five minutes apart on Mac OS X 10.7.3 in both partitions.
If I then, boot back into the work partition, and bring up Speedtest.net not only on there, but also on a couple of other machines, and set them all to check simultaneously, the combined total of the download speeds is - guess... yup, 56megs down and around 14 up.
Aside from quite fancying my connection giving me that full 20megs up (OK, I know, it'll be 19 or so), I'm really quite happy with this - and it does point out that, in all likelihood, severely fluctuating speed tests may not necessarily be line-related. If I wasn't able to reproduce all of this more or less at will, I may have thought differently, but it's an entirely repeatable excercise.

Yes indeed, none of the speedtests are reliably accurate all the time as their servers and routes to the server are subject to varying conditions. Speedtest.net is very dependent on which server you select, as their automatic server selection chooses based on ping results, which does not always give you a server with the fastest data rates (my results vary from 35 to 70Mbps, or as low as 2Mbps if you go out as far as New Zealand ). BT's main http://speedtester.bt.com/ (diagnostics) is up the pole for most of the day and is only any use for finding out your profile. However, their beta test is pretty good and is always worth trying: http://speedtester.bt.com/beta/speedtest-remote.jsp
BBMax is often said to be the best one but that could just be because it uses a much smaller download file and the test lasts for a shorter period of time. That means there is less scope for varying line and server conditions to intervene, and for Internet Security programs to slow things down.
So what I do is:
a) Turn off my Internet Security program (this can be very important)
b) find the fastest speedtest.net server and use that result
c) use BT beta speedtest (as I already know my profile)
d) check BBMax
The results of these three methods are nearly always between 69.x Mbps and 71.x Mbps, my profile is 72.8 Mbps. I don't think you'll ever get your 19Mbps upload by the way as I am on a 20Mbps cap but the fastest upload speed I've seen is 16.x binary Mbps and 17.x decimal Mbps.

Unable to activate my high speed internet account with a mac os 10.5

I have a big problem with the activation of my line. I have subscribed to high speed internet.
The agent came to my house to install the jack but when I'm trying to run the installation on my computer with the cd or directly with internet it's stops when smart acces opens (I have a Mac OS X 10.5). Could somebody help me ? Thanks

In almost all cases, internet is "plug and play" on newer computers.
If you need to install filters, they need to go between the phone and the jack for every phone you have on the same line as the DSL. The modem does not get a filter.
If you need to set up your username and password, you will need to log in with your default Verizon-assigned id. If you were not given this, then contact tech support and ask for your "vzid" and have them reset your password. You should then be able to log into verizon.net and click on the My Account page. On the My Account page, you can set your username, create sub accounts, manage your billing, add an alias to your account, etc.
Does that cover what you needed, or is there something more?

Why are the wi-fi speeds bad even with my own rout...

When I connect with an Ethernet, I get amazing speed of 74/76mb download. but soon as i connect via wi-fi with the hub or my own router, speeds dropped till about 20/25mbs.. whats causing the problem, I have tried to change channels but to no effect..
no question of the speed is great via the ethernet connection so i know there is no issue with the line or other wise, its just an wi-fi issue
Solved!
Go to Solution.

I've got a Netgear WNDR3700v2 and I get the same (using either band 5Ghz or 2.4Ghz), my throughput seems to max out at 29Mb/s (can get 34 if I turn off wireless encryption - but not prepared to do that)
I don't generally use wi-fi for serious file transfers though, so it's not really a big concern for me but would be nice to hit full speed on wireless

Slow memory card raw import speed (~20MB/s with USB3.0)?

Hi all,
For a long time now, I have been experiencing painfully slow (copy) import speed from memory cards to Lightroom.
For example, importing a fast CF card full of Canon 1D mark4 raw (cr2) photos yields a raw transfer speed of about 18 MB/s . This is ridiculously slow, considering that I'm using 90MB/s rated cards with USB3.0 reader in USB3.0 bus. With that speed, copying one full 16GB card takes over 15 minutes. That really doesn't feel like modern computing to me.
With Blackmagic Disk Speed Test the same device gives read rate of 60MB/s. Dragging and dropping the folder of all raw files in Finder takes about 4 minutes, which corresponds to the Disk Speed Test rating. CPU usage is around 8-10% during import, and standard preview rendering does not start until completing the import. I've also tried the same thing with Thunderbolt-FW800 adapter connected to Delock CF card reader and have pretty much the same results.
Does anyone have similar issues or am I the only one suffering from low transfer speed?
I'm guessing that Lightroom has some ancient algorithms for handling the file copying instead of accessing the memory card with the system file transfer.
Example:
Memory card: Sandisk Extreme Pro 16GB, nominal speed 90MB/s
Reader: Lexar Professional USB 3.0 CF+SD reader
Computer: Macbook Pro Retina 13 2012, 256 ssd
Lightroom 4.3

Thanks for the comment Matulaitis.
I find it rather silly that getting new photos into Lightroom in the first place is painfully slow.
But that's not a problem major enough to be fixed asap by Adobe, I would guess.
Matulaitis wrote:
I finally gave up importing directly into Lightroom due to slow speed and stalling/failing import issues.
Now I copy the files from the card to the folder using another software utility, then synch the new stuff into the catalog. This works without problems, all same hardware.
LR 5, Windows 7 64bit, USB 3, tried many card readers, different USB ports, separate USB 3 card, none helped Lightroom. This is not a new problem, has been present through various versions of LR, though 5 is the worst in this regard for me.
LR would usually work ok for a few files, but almost never has been reliable for a lot of files (say 1000-1500 new files).

Speed of Lightroom with files on network attached storage if preview files are already generated

I'm trying to figure out if it's practical to use Lightroom to access/manipulate files on network attached storage.
Specifically, suppose I've already generated the 1:1 preview files, and these preview files are on the local hard drive. Does it matter then if the raw files are located physically on a NAS v. on the local hard drive in terms of the speed of Lightroom and ease with navigating from image to image?

Andrew,
Unfortunately the catalogs can have multiple issues when saved over network due to lot of network variables.
The same is covered under Lightroom FAQ's as below:
Can I store my catalog on a network?
No. There are too many variables in a network configuration to guarantee that the catalog won't get corrupted.

Browsing speeds slowing down with my AE. Is it Leopard or the AE? Opinions

I noticed after the 10.5.4 update that my browsing began to slow when connected to the AE. I've tried various browsers and they all began to function the same way--slow.
I thought maybe it had something to do with my AE so I connected my cable modem directly to my iMac and behold, I was browsing the net at lightning speeds again.
I've had my AE for a few months (it's not the new AE with "N" speeds), I'm wondering if it's the AE or Leopard. Also, I'm wondering if I can return it to the Apple store and get a new one?
My mac indicated that my AE signal is at full strength and the light is green on my AE, but the browsing can get slow.
Opinions? Should I try to return the AE to the store? What will hitting the reset accomplish?

Just for starters, did you save your network preferences to remember all Airport/wireless networks and have you stored the passwords in your keychain so they automatically connect?
You can even choose which network to join first and in which order. Such as your home network first, then school, then public wi-fi. Put them in the order of which you're at most. Then Airport will automatically find the ones stored in your computer.
Of course, if you've already done this, then it's either a Leopard "quirk" or your Airport card. (Which you probably already figured out).
