Screen Sharing is very slow

I use my Mac Pro to do maintenance on my Mini in the home theater using Screen Sharing. This worked great with Leopard, fast and smooth. I've now upgraded both to Snow Leopard and it has become extremely slow. Moving windows is glacially slow, for example. There is often a several second lag between a button press and resulting action. I haven't found any discussion about such a condition and don't know what to look for. Can anyone help me? Thanks.

I have the same problem, I think. The 2 computers take ages to connect to each other, with screen sharing and also to connect as a share in finder. This is only since updating to Snow Leopard, with Leopard everything was dandy

SAP SNC Portal DCM screen performance is very slow and times out

Friends,
SAP SNC Portal DCM screen performance is very slow and times out when user trying to pull data using customer location
What are the cleanup activites we can do to improve the overall SNC performance ?
We did open OSS message but so far no reply from SAP , Is there any one faced performance issue ?
User/vendor is complaining about slowness , query is standard SAP and its taking more time .(table - /LIME/NTREE) , It looks like number of data are huge causing this problem related to LIME/NTREE table. What are the options to improve the performance ?
Thanks in Advance
Hanuman Choudhary

hi Team,
Pls . note the advise from SAP below, IS there any have experiance of archiveing /LIME records ?
Please advise how to start & what the steps in archiving ?
Thanks in advance
I had a look at the DCM query performance in PH1 system and figured out
that most of the time is spent at the LIME layer of database. The
following LIME tables are having far too many entries and is causing
the bottleneck during the query execution.
/LIME/NLOG_QUAN - 38,165,467
/LIME/PN_ITEM - 19,116,518
/LIME/PN_ITEM_TB - 19,154,124
These tables are storing the historical information about LIME(stock)
updates. Since these table grow with each change/update of stock
information, it will slow down the performance of the system over a
period of time. And to avoid the slow responses, the tables should
ideally be archived on a periodic basis to keep the data volume as
minimal as possible. You may have to discuss with the Business to
determine the number of days of LIME record you would want to retain
in the system. I would strongly recommend you to consider the LIME
archival retaining the minimum days (<=60 days) of historical
information. You can find more information about the Lime Archival
in the Sap Help link:
http://help.sap.com/saphelp_scm2007/helpdata/en/44/2a83121dde23d1e10000000a1553f7/frameset.htm.
Kindly get in touch with your BASIS consultant for the LIME archival.
The application performance should definitely improve after the LIME
archival. Please do not hesitate to get in touch with me in case you
require any further clarification in this regards.
Best Regards

Messages Screen Sharing is super slow

So, in Yosemite, Apple introduced native screen sharing. I used to do screen sharing via AOL IM in Messages, but have now been trying Apple's native version. It is, however, painful slow. Especially when compared to using AOL IM. Is anyone else having this issue? Have you found a way to speed it up?
Also, when using native screen sharing, the person requesting the screen share is introduced using their [email protected] user account. For users like me who use the (much) older @mac.com handle, is there a way to have Messages identify you as such, instead of using the @iCloud.com handle?
Thanks in advance.

Home sharing is very slow

I'm not sure when this happened and obviously I don't know why... all my devices are up to date. My homesharing from my imac to appletv is insanely slow and I can't mirror at all basically. I need help!!
i believe its a 3rd gen apple tv and a 2011version imac... trying to watch my home movies on the big screen.
THANKS!

Well, I spent long time with Apple Phone support, they made me delete the library, move some iTunes file from Library folder on my MBP but that didn't help.
I also did reset my Apple TV, and did all the settings again. No change.
I read somewhere on this forum itself I think to remove "Share my Library on local network" option from iTunes preferences, under sharing. As per the suggestion, this is an old option, and when you have home sharing on, you don't need this to be checked. More over it causes sharing to be slow. So after I unchecked it, I ATV3 and my MBP on for about an hour, and when I came back, it was all just perfect!

MMC Snapin Shared folders very slow on windows 7

After the roll out of windows 7 i installed the RSAT SP1 on the 7 32 bit machine.
Here i created a mmc snap in with users and computers and active sessions.
The users and computers are running fine but the active sessions very slow, on xp it was running great.
I allready turn off netbios over tcp/ip and deleted the cache on the win 7 client, no result.
In our environment (2003r2 and 2008r2) i am not allowed to change adapter settings of the servers.
Is there a fix for the client site with RSAT?

Hi,
We may test the issue via the steps below.
1. Click Start, type in Secpol.msc and press Enter.
2. Expand "Local Policies" and select "Security Options"
3. Locate "Network Security: LAN Manager Authentication Level" in the list and double-click it.
4. Change the setting from "Send NTMLv2 response only" to "Send LM & NTLM - use NTLMv2 session if negotiated"
5. Network Security: Minimum session security for NTLM SSP Based (including secure RPC) Clients
6. Change the setting from "require 128 bit" to unchecked (No Minimum)
7. Click OK, and exit.

Connecting iPad to movie library via Home Sharing is very slow to connect (20 mins +)

Hi, I'm trying to connect my iPad to my movie library and it is very slow. Is there any tips to get it to connect. I have an iPad Air (ver 1) and iMac (late 2012). I restarted all the devices and I am able to connect my iMac library to my Apple TV. Any feedback is greatly appreciated. Oh and everything is all updated.

Front Panel binding of shared variables very slow initialization / start

Hello @ all,
I am using a server running Windows2000 and LV 8 DSC RTS for datalogging. All shared variables are deployed on that server.
I am now facing the problem, that all front panels running on the clients using the network shared variables on the server take very long to sync on startup. First the flags on the controls bind to the shared variables turn red, after up to ten minutes they start to turn green. The panels use up to 40 controls bind to the shared variables.
All firewalls are turned off. I tried to connect the client to the same switch the server is connected to. Same problem. Does anybody have a clue?
Thx for your quick answers.
Carsten

While I can't offer any solution to your problem, I am having a similar issue running LV8.0 and shared variables on my block diagram (no DSC installed).
When using network published shared variables, it takes anywhere from 30 sec to 4 min from the vi start for any updates to be seen. Given enough time, they will all update normally, however this 4 minute time lag is somewhat troublesome.
I have confirmed the issue to be present when running the shared variable engine on windows and RT platforms, with exactly the same results.
In my case, the worst offenders are a couple of double precision arrays (4 elements each). They will normally exhibit similar "spurty" behavior on startup, and eventually work their way up to continuous and normal update rates. Interestingly enough there are no errors generated by the shared variables on the block diagram.

Viewing full screen images gets very slow in PSE 5&6

In full screen preview mode, when going from a horizontal image to a vertical image, it takes several seconds to go to the next image.Have tried turning off and on the resizing option and it had no effect. Viewing 2mb jpgs from a Nikon D200.Have Win XP 64, 8GB Ram, dual core processor and a middle of the road video card.
Could this be a video card issue? Would going to PSE 8 help. does PSE 8 utilize 64 bit OS?

Very interesting. I'm guessing that the portrait photos were rotated by the camera by setting the Orientation field in the photos' metadata, and that for some reason, PSE on your system requires a lot of time to properly rotate them on the fly in Full Screen view. When you edit the photo in the Editor, it rotates the actual image, rather than setting the Orientation field.
For a couple of test photos, try following steps 1 - 3 of this FAQ:
http://www.johnrellis.com/psedbtool/photoshop-elements-faq.htm#_Photos_not_properly
This should have the same effect as editing them in the Editor.

TS1702 The default Camera application is not responding, it comes with black screen. Functions on the screen are unresponsive, very slow.

Dear community,
The default camera application became un-usable in my iPhone5. Cannot operate camera at all. It comes with a blank/black screen, camera controls are unresponsive, front-back camera toggle switch takes couple of minutes to response but with a blank/black screen both front and back.
I searched solutions and applied but none seems to work. I reset my phone, started as blank, with no user account, still camera is acting same (or rather not acting). Other apps that use camera give error when try to access the camera such as whatsap and skype. Facetime comes with a very blurred view. Couple of screen shots are attached.
I think need to erase and reload the camera program but I could not find how to do it. Is it possible? or is there any other suggestions?

Hello hakanid,
The following article provides some useful troubleshooting steps that can help get your iPhone's camera working.
Camera isn't functioning or has undesired image quality
If the screen shows a closed lens or black image, force quit the Camera app.
If you do not see the Camera app on the Home screen, try searching for it in Spotlight. If the camera does not show up in the search, check to make sure that Restrictions are not turned on by tappingSettings > General > Restrictions.
Ensure the camera lens is clean and free from any obstructions. Use a microfiber polishing cloth to clean the lens.
Cases can interfere with the camera and the flash. Try gently cleaning the lens with a clean dry cloth or removing the case if you see image or color-quality issues with photos.
Try turning iPhone off and then back on.
Tap to focus the camera on the subject. The image may pulse or briefly go in and out of focus as it adjusts.
Try to remain steady while focusing:
Still images: Remain steady while taking the picture. If you move too far in any direction, the camera automatically refocuses to the center.
Note: If you take a picture with iPhone turned sideways, it is automatically saved in landscape orientation.
Video: Adjust focus before you begin recording. You can also tap to readjust focus while recording. Exiting the Camera application while recording will stop recording and will save the video to the Camera Roll.
Note: Video-recording features are not available on original iPhone or iPhone 3G.
If your iPhone has a front and rear camera, try switching between them to verify if the issue persists on both.
My issue is still not resolved. What do I do next?

Slow/lagging performance while screen sharing in OS X.

I am running two "headless" '09 Mac Mini. I control them with Screen Sharing in OS X from my MacBook 2.1ghz & MacBook Air 1.6ghz. After 10.5.7, screen sharing is very slow in response. This is the same for all my Macs, not just the Mini. My wireless bandwidth is 14 mbps down & 8 mbps up so it is not my network connection. Please look into this.
Thank you,
Mike

Please look into this.
This forum is for the exchange of information between Mac OS X customers. It is NOT a communications channel to Apple.
If you want to report this to Apple, then use one of the following methods:
<http://www.apple.com/feedback/macosx.html>
<http://bugreporter.apple.com> Free ADC account needed for BugReporter
If you want fellow customers to take a stab at diagnosing this, please provide some additional information.
How are the systems connected? Ethernet, WiFi, over the internet (some or all of the above may apply)? A simple diagram such as
modem -- ethernet --> wifi base station
wifi base station -- 802.11n -> MacBook Air
wifi base station -- ethernet -> Mac mini A
wifi base station -- 802.11g -> Mac mini B
would be useful.
If over the internet, what method do you use to establish a remote connection, and did you have to make any special configuration setups to allow that connection?
If WiFi, is it 802.11b, 802.11g, or 802.11n. If 802.11n is 'n' working in the 2.4GHz or the 5GHz frequences (it matters).
If using the 2.4GHz frequences (802.11b, 802.11g and 802.11n in 2.4GHz mode) can all be affected by interference from neighbor's WiFi equipment using the same channel, 2.4GHz cordless phones, 2.4GHz baby monitors, microwave ovens (I'll discount the microwave oven unless you cook 24/7).
You can check on the neighbor's WiFi channel using with a utility such as
AP Grapher
iStumbler
KisMac
AirRadar
You should be able to find any of these utilities at

What Mac OS X 10.5.7 installed on ALL the systems, or just the MacBook Air?
Besides upgrading to Mac OS X 10.5.7, have you made any other equipment changes (new router, new ethernet switch, moved equipment to a new location, played with any router configuration settings, etc...).
Actually some of this information would useful to Apple as well, if you should choose to report it to Apple.

Screen refresh for participants very slow on beehive web conference

When I am sharing my desktop with participant on Beehive web conference, the screen refresh is very slow for the participants. It almost takes 1 minute for the screen to refresh on the participants screen. I am on Windows 7.
Appreciate your help.
Thanks in advance.

Hi,
Given we have very little control over the network bandwidth of the end user it is difficult to determine what the problem could be - normally the refresh is reasonably fast but if there are a lot of users or a restricted bandwidth it can show down a bit.
One trick to aid the display is to not move the mouse around the screen - pointing to the entities on the page will increase the amount of information being sent. If you can click one and wait for the screen to be rendered at the other end before continuing it may be a bit quicker.

Very Slow / Lag When Screen Moves...

Hi Guys,
I’m really a newbie when it comes to AS3 – so really a total newbie when it comes to using it to develop iPhone games/apps, but I have used AS2 for years now
I’ve been trying to do a simple test – Just use mouse events to move a screen around depending on what is pressed. No Characters/hittests/etc.
What I have created works great on my pc – very smooth, and even on the iphone, the controls work as expected – but the problem is how SLOW everything is running. Pressing the "UP" arrow - makes the screen move, but very SLOW and Jumpy.
I have tried using onkeyframe and using a timer – but both are very slow.
Typically when I made games in AS2 – the “level” would just be a single BIG movieclip – as shown in “Example A” – but this was very slow on the iphone, so I tried a tile based approach (“Example B”), which reuses the same movieclips, it just moves them and renames them – trying to cut memory usage down, only loading what is needed - but still its slow. The total size of the "level" is only about 3x bigger than the iphone visible screen.
I have made sure all variables are done correctly: var thisVar:int = 10; etc and have enabled cache as bitmap. I have replaced all vector graphics with jpegs, and followed the guide on how to optimize code for iphone development – but nothing seems to work, everything just lags as the screen moves/updates – but everything works great on my pc.
Can someone please explain what I am doing wrong? Is there a way to cache the whole map before the game loads? Which is the correct way to make an iphone game where the level is bigger than the default screen - tile based or a large level graphic.
Thanks so much for any help! I’ve been trying to get this simple test working for 3 days now – but documentation is limited at the moment.
Cheers!

This should be better:

var totalGalleryItems:Number = 4;
var slideCounter:Number = 0;
var gallery_items:Sprite = new Sprite();
addChild(gallery_items);
addPages();
stage.addEventListener (TransformGestureEvent.GESTURE_SWIPE, fl_SwipeToGoToNextPreviousFrame);
// create pages
function addPages():void
addShape(0, 0, 0xff0000);
addShape(768, 0, 0x00ff00);
addShape(1536, 0, 0x0000ff);
function addPage(xPos:Number, yPos:Number):void
var p:Bitmap = new Bitmap(new bookPage());
p.x = xPos;
p.y = yPos;
gallery_items.addChild(p);
function addShape(xPos:Number, yPos:Number, col:uint):void
var s:Shape = new Shape();
s.graphics.beginFill(col);
s.graphics.drawRect(xPos, yPos, 768, 1028);
s.graphics.endFill();
gallery_items.addChild(s);
function fl_SwipeToGoToNextPreviousFrame(event:TransformGestureEvent):void
if(event.offsetX == 1)
if(currentGalleryItem > 1){
currentGalleryItem--;
slideRight();
else if(event.offsetX == -1)
if(currentGalleryItem < totalGalleryItems){
currentGalleryItem++;
slideLeft();
function slideLeft(){
gallery_items.addEventListener("enterFrame", moveGalleryLeft);
function slideRight(){
gallery_items.addEventListener("enterFrame", moveGalleryRight);
function moveGalleryLeft(evt:Event){
gallery_items.x -= 76.8;
slideCounter++;
if(slideCounter == 10){
gallery_items.removeEventListener("enterFrame", moveGalleryLeft);
slideCounter = 0;
function moveGalleryRight(evt:Event){
gallery_items.x += 76.8;
slideCounter++;
if(slideCounter == 10){
gallery_items.removeEventListener("enterFrame", moveGalleryRight);
slideCounter = 0;

Screen moves very slow when i drag a window from one corner to other.

Hi,
We are taking RDP to windows server 2008 R2 standard using Thin-clients.
If I drag a window of explorer or browser to other end of screen it is very slow.(it will work as desktop without video drivers).
Is there any solution for this.
And By the way what is application getting accelerated mean.
Thanks in advance...........

Hi,
Please check if a normal physical computer has the same issue. If not, I’m afraid that the issue is related to the performance of Thin Clients.
Please update the firmware and drivers of your thin clients to the latest and try again.
Thanks.

Apple File Sharing very slow with Mountain Lion

I've noticed since upgrading to 10.8 the transfer speeds over a LAN via AFP (File Sharing) are VERY slow.. in some instances. Based on the behaviour i'm guessing it has something to do with the amount of items.
for instance:
A folder that contains approx 122mb worth of 1500 small files takes me about 50 seconds to transfer while a long audio recording with a greater filesize of 125mb takes only 11 seconds.
using SCP from the command line the same 122mb folder took only 19 seconds while the audio took 10 seconds.
after performing the same operations on a computer running 10.6 I can deduce that the problem is on the receiving end. Audio file transfer times were the same, however the same folder of items took only 27 seconds when it was transferred to a computer running 10.6 regardless of which OS the computer sending the file was running.
apparently handling a greater number of files increases transfer time for both methods but AFP is painfully slow with 10.8 on the receiving end.
any thoughts or suggestions?
I've read a couple threads about people having trouble with Time Machine running slowly.. i wonder if this is related.

Same problem here. I just upgraded from Lion to Mountain Lion. I only got 19 GB of space, but Time Machine wants 10 hours, whereas in OSX Lion a full backup would take just under an hour, and incremental updates were lightning fast.
I even sat it up to do it overnight, but on 8 hours it was only half way through only 10 GB. I can't live with that in the future.
Im trying to backup on a SD card which seems to work very good in Lion. Im on a 2012 Macbook Air using a SSD.
My bite of the apple has been somewhat sour. I tried reformatting the SD card, well knowing that I would lose old backups. But still the backup is extremely slow. Now I can't install Lion or Mountain Lion from scratch without having to wait 10 hours for TM backup or installing tons of applications and settings again. Bummer. I'm never going to early adobt a OSX upgrade again.

Micro disconnections + Very slow periods

I have had infinity for 3 months, the speed is okay. Usually around 67 and 20 up on speedcheck.
However, when viewing bbc iplayer or playing a game or using Adobe Connect ( conferencing software ) , I get what feels like micro disconnections, or loss of data.
Adobe connect is unusable, due to the disconnections making it so I have to be reconnected each time. Screen sharing is ultra slow. In - game I have spikes that I assume are the same.
BBC live keeps losing connection too.
