Slow video buffering since installing maverick

I have had slow video buffering since installing Maverick,any suggestions?

I have had this issue before as well
My system was also occasionally completely unresponsive after the Mavericks upgrade. (It's been through 4, now)
So, I backed up all my files with time machine and performed a clean install and all my issues were compltely resolved. Including the slow buffering. Although doing this was a tedious, long, and aggravaiting process, my issues were resolved. Good luck, or whatever, if you are still having this problem as this (even though not an ideal one) is a solution.

Very Slow Video that Does Not Fully Load on Macbook Pro

Hi,
I have a macbook pro from 2007 (Mac OS X 10.4.11) and I have never had any issues with streaming video until yesterday. I have fast internet, and I can browse quickly, but my video is recently being very slow and won't fully load. It always says 14 out of 16 things loaded or some other number when I try to play a video. I have tried resetting Safari and emptying my cache to speed it up several times with no luck. I have Safari 4.1.2. I am wondering what I need to do to get this fixed as soon as possible because there are some important videos I need to watch for classes.
Thanks so much for your help!

"I have tried resetting Safari and emptying my cache to speed it up several times with no luck. I have Safari 4.1.2."
Do you have the same problem w/streaming videos using other browsers? Suggest that you re-post over in the Safari for Mac forums as your problem is not MBP related but rather software.

Very slow video downloading from iTunes

I have a FIOS 75Mbit connection (and get can 75Mbit on my N-router and Macbook Pro's WIFI). But my new 1080p Apple TV is another matter. Two minute trailers take longer than 2 minutes to download. Half hour HD TV shows can take 90 minutes to download! And if I try to watch a movie I rented, Apple TV tells me it'll be ready to watch in "about 5 hours".
So my immediate reaction is ***. Any ideas why my wireless performance is so great with my MBP and so terrible with my AppleTV (just 10 feet away)

I stumbled across this thread looking for help with the same issue...slow to very slow movie downloads from iTunes.
Changing the DNS, both on my iMac as well as my Airport Extreme router helped.
I'm on Comcast and generally get around 33Mbps downloads via speedtest.net. Based on several Namebench tests Google's Public DNS (8.8.8.8) has always been on top and I've always configured my router and Macs using the top 3 Namebench recommendations with Google at #1 position. However while downloading movies from iTunes Activity Monitor showed very sharp "Data received/sec" rises and falls...anywhere from 4.40MB/sec to 100KB/sec or sometimes zero. Most of the time it would start off well, but trail off to very poor and sporatic speeds after about 30 seconds.
Per finaleMile's and other's recommendations elsewhere I removed Google Public DNS from the settings on my router and iMac and things improved with respect to stability. Although the "top speed" of about 4.40Mbps didn't improve, downloads did smooth out and remain between about 2.30Mbps to 4.10Mbps during the entire download. Not speedy but a marked improvement in stability and overall download time.
Thanks for the tip!
BTW, I've found that during regular web surfing, using Google's Public DNS is faster so I re-add it after downloading movies from iTunes. It's a bit of a PIA, but worth it. Wish there were a better option though.
FWIW I tend to download rented and purchased movies to iTunes on my iMac and then play them back via my Apple TV3 rather than "stream" them directly from iTunes. That way if there are external network problems they won't have a negative impact on our viewing experience.

Satellite L730 / L735 very slow..buffering online content, startup etc

I have only owned this since 26th May this year, and I have found the performance really slow.
I can't watch online content.. it takes ages buffering and has gotten worse over the past few weeks even though we have got a strong connection.
Also it is taking about 10 minutes on startup!!
Any ideas, seems a bit poor to be having such serious problems so early on? We have checked and defragmented the hard disk drive and that hasn't helped at all. There is very little stored on the HD.. less than 10% used.

> I can't watch online content.. it takes ages buffering and has gotten worse over the past few weeks even though we have got a strong connection.
The video streaming depends on the server where the video is hosted too!
If the server is overloaded, the performance can go down and this affects the streaming performance.
Did you notice the slow performance using other software too?
Please also note that background processes which are running in background of the operating system can slow down the system performance.
Usually you can disable not necessary background processes using msconfig.
But be careful with that. This can affect the notebook functionality too. If you dont know the single process, google for that to get more details.
I use the CCLeaner (freeware tool) to improve my notebook performance. Maybe it could be useful for you too.

Very slow video streaming.

This problem started around a week ago. And watching videos being one of the main uses of this Macbook it's quite a frustrating problem. Especially as I don't know what else to do about it.
About my Mac:
Macbook 6.1
2.26GHz Duo Core
2GB 1067 MHz DDR3
Basically, from last week, even the smallest of videos with durations of 2 minutes can be a 15 minute task due to waiting for them to load before I play them.
I've tried the 'fullscreen trick' which I see on a lot of support forums, it doesn't make a difference. I've updated the OS X to 10.6.4, I've updated to the latest version of Safari, updated Adobe Flash, I even tried FireFox (which I cannot stand anyway), which did nothing, if so, made the problem worse.
I've checked my storage space and there's a lot left.
So now, I'm stumped. And would be very grateful for some extra help ...

Try Google's Chrome browser as well, just in case.
Have you tried connecting via Ethernet instead of wirelessly?
Have you tried another use account?

Safari 3.2.3 Online videos very slow

Hi. I just purchased a MacBook Pro with Mac OS X 10.5.7 and Safari 3.2.3. Videos online - such as YouTube, news sites, etc. - are very, very slow. The buffering is extremely slow and the videos stop, start, stop, start and sometimes just hang. Has anyone else experienced this and is there a fix out there?

Update to Safari 4.

Live Cam Voice on HP DV8305 -- Video image very slow

I installed Live! Cam Voice on my HP DV8305 succussfully, it works, but the video image is very slow. it needs about 30sec to capture a frame, sometime just stucked. I changed the Display Adaptive Driver, used differrent USB IF, checked my CPU and Memery usage, my HD space, use differrent IM -- skype, MSN, .... Any one can help?

As further information, the issue seems to be with the exposure setting. When I turn auto exposure off, then set exposure down as low as it will go, the picture darkens, but the frame rate goes up. I don't have this problem with my Logitech QuickCam Orbit -- I'm not sure if the problem is with the firmware, or if the CMOS sensor in the Live! Cam Voice is just smaller.

Thank you very much for your reply gdgmacguy :) I did all you suggested apart from restore as new device . Didn't know I could do that . After restore I did restore from back up only, as I didn't want to end up without contacts details on my phone. If I restore as new device how do I get my all contacts? Still will have to use back up? Sorry if it sounds like I don't know what i am doing, i just have no one to ask who would know. Thank you

My MacBook Pro gets very slow while doing work like watching movies and using net .. video gets lag very often

My MacBook Pro gets very slow while doing work like watching movies and using net .. video gets lag very often and while surffing on net it gets very slow ...

First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
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.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
Otherwise, take the steps below when you notice the problem.
Step 1
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 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 System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
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 (command-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.

Video .f4v very slow

Hello:
I'm having problems playing f4v video is very slow. The size is 100 MB and resolution 1280x720. When I play out of Flash it reproduces well.
I need to play in Desktop application not over Internet.
What I'm doing bad? Is there anywhere to play well or wich is the better option to do it?
thank you very much.
This is my code:
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.media.Video;
import flash.events.AsyncErrorEvent;
//fullscreen
stage.displayState = StageDisplayState.FULL_SCREEN;
var conexion:NetConnection= new NetConnection();
conexion.connect(null);
var display:NetStream = new NetStream(conexion);
display.play("videos/ocioelecer.f4v");
var video:Video = new Video(1280,720);
video.attachNetStream(display);
addChild(video);
display.addEventListener(AsyncErrorEvent.ASYNC_ERROR, noshow);
function noshow(event:AsyncErrorEvent):void{
//no show error
display.addEventListener(NetStatusEvent.NET_STATUS, statusHandler);
function statusHandler(event:NetStatusEvent):void
    switch (event.info.code)
        case "NetStream.Play.Start":
            trace("Start [" + display.time.toFixed(3) + " seconds]");
            break;
        case "NetStream.Play.Stop":
        //End video
                        trace("Stop [" + display.time.toFixed(3) + " seconds]");
        (root.loaderInfo.loader.root as Object).removeSWF();
            break;

100MB played locally is nothing. Most HDs have burst cache which can load up to 200MB instantly off disk. You shouldn't even need to (but might want to on a really 'value/green' rated drive) set the buffer to require 1 second of data before playing (bufferTime = 1).
Are you using any kind of integrated graphics, like using a Z-esque Intel chipset with Intel 2000/3000/4000 graphics? Sometimes people over-estimate how well their built in hardware decoders perform.
You always want to add Event listeners before you invoke a method that uses events. In your code you're adding listeners AFTER invoking a 'play(...)' method. Just for best practice, run the load(...) last.
Lastly is the video available for inspection? 100MB for 10 seconds is 10MB/s, which is really only required in excessively high quality rendering with a huge gaumet with high motion. 9mbit is average full quality 720p (which is 1.25MB/s). You may have your bitrate set too high as moccamaximum mentioned if you are not in that video situation or striving for lossless video in ultra high motion.

Playing video on eMac is very slow.

Hi I have an eMac 700mhz with 640mb of SD Ram running Mac OS X 10.3.9 and video is very slow but weirdly videos on YouTube play fine and are not choppy or slow at all.
I have the latest version of flash that will run on this OS : Adobe Flash Player 9.
Any suggestions ?
Thanks

Follow Dale's advice first to run Repair Disk; if there are any disk directory issues, other fixes will just be wasting time until the underlying directory problems are fixed.
Other things to consider: how much free space is there on the hard drive? Unix-based operating systems, which includes OS X, require disk space for scratch and swap files; burning optical discs requires enough space for creation of a temporary file as large as the physical disc being burned; and other programs may have their own cache requirements. If free space on the boot hard drive runs below 1 GB, the computer will begin to behave poorly can can potentially end up unable to boot. Deleting unused data and files (old .dmg images used to install old programs are a prime candidate for deleting) will help. If space is really tight, get an external Firewire hard drive and move user data there:

iPhoto: How to move the iPhoto Library Folder
If you normally shut down an OS X Mac overnight or leave it in system sleep, the cron maintenance tasks cannot run in their nominal 3 am timeframe. (Display-only sleep allows the maintenance tasks to run). Tiger 10.4.2 and later will (nominally) force the maintenance tasks to run after sufficient time has elapsed, although the timing on that is subject to dispute. You can leave the Mac in display-only sleep a weekend or two a month; you can manually Force Background Maintenance; or you can use a third-party utility such as OnyX to run the maintenance. Note that any system utility you use must be compatible with the OS version (e.g., use the Tiger version of OnyX with 10.4.x).

HT4623 I have no sound. I can't watch any videos. Everything is running very slow. Please advise

I have no sound even though the volume is turned to max. I cannot watch any videos on face book or YouTube. Games are running very slow. I've tried updating but it says software is up to date.

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

Videos won't stream (eg youtube) and safari very slow

Hi, I have 2 problems and would really appreciate any help
1 - safari very slow to open pages and has been like this for weeks. I have seen a solution to change to 'opendns' under System preferences > network > advanced tab but I cannot see an option for that. I think this may be my problem as Google always opens quickly. Can anyone elaborate on this solution?
2 - Videos won't stream and just hang with circle (e.g on sites like youtube) which started about 1 week ago. Only thing I have done differently is watching megavideos on unknown site. I have tried the solutions given under other threads (e.g. deleting cache files and uninstalling and reinstalling adobe flash). This seemed to help slightly the first time I tried it but still took approx 60s to stream 1 minute video. Has now reverted back to not streaming.

To set up a test account, open System Preferences > Accounts, click on the padlock icon to unlock it, then click on the "+" sign, name the account "test" and leave the password field blank, since you don't need the account that long; you can delete it later.
Quit System Preferences, log out of the regular user account and into the test account, then try using Safari to load pages and videos to see if the problem continues there.
Other things you can try in your regular user account that may help your problem or solve it are this:
1. Go to Home/Library/Caches/com.apple.Safari and delete the contents of that folder.
2. Go to Home/Library/Caches/com.apple.Safari/Web Page Previews and delete the contents of that folder.
3. If you don't want to use the Top Sites or Cover Flow features, open Terminal and paste in this command:
defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2
then press Enter or Return and quit Terminal
4. Go to Home/Library/Caches/Metadata/Safari and delete the contents of that folder.
5. Go to Home/Library/Caches/Safari and delete the contents of that folder.
6. Go to Home/Library/Safari and delete these files (if you have them):
Downloads.plist
History.plist
Form Values
LastSession.plist
WebpageIcons.db
Then Repair Permissions, restart Safari and see if the speed is improved.

No magical keystroke remedy. The causes for this can be complicated.
