Screen Sharing freezing and high CPU usage

Hello all,
I use screen sharing to remote my mac mini as a media server connected to ma HD TV to play movies, music and surf.
Since I upgrade to mavericks on my macs (Macbook Pro Retina and my Mac Mini) I have some troubles with the screen sharing feature.
No problems with the login step, the connexion is fast, all permissions are OK (I saw there were a bug with some RDP release) but sometimes, when I use fullscreen software as VLC, Firefox, etc (not the native apple full screen feature, I just clic on the + at the top of the window), my sreen sharing freeze and I can't do or move anything on the remoted mac mini. I'm unable to close (or reduce) the screen sharing app too, it's totaly busy (But I can see the movie or the website on the 2 computer, there is no deconnection)... I have to kill the process through the monitoring activity.
During the freezing time, I try to use vnc light from my Iphone and I have no problem, I can move the mouse, reduce le VLC windows... As soon I reduce the VLC windows, the screen sharing works again. I also use the logitech TouchMouse to remote the mouse, everything work fine.
Here are a screen shot of the monitoring activity of the Mac running the screen sharing app, we can see that there is a very high CPU usage when I use VLC in fullscreen on my mac mini. The first is in normal mode. The second is in freeze mode. Screen Sharing is named "Partage d'écran".
Can someone help me to fix that, everything works fine with Mountain Lion.

I have a Macbook Pro 13.5" 2.8 GHz 4 core (2 real, 2 hyperthreaded) i7 machine running with 1920X1200 display, 3 virtual screens and VMWare adding a few virtual screens (full sized). I have another Macbook Pro 15" with 2.6 GHz Haswell 8 core (4 real, 4 hyperthreaded). I see the problem using Screen Sharing on the 15 inch (Retina screen) mode simulating 1920 X 1200 pixels using Screen Sharing to the 13.5" Macbook Pro.
When I get the ScreenSharing problem, I have identified it as related to the VMWare screen on the 13.5" Macbook Pro being shown through Screen Sharing on the Retina Screen. Before you conclude it is a VMWare problem, the computations are only on the Screen Sharing client side, not on the server side running VMWare. The mouse gets unusable through Screen Sharing. If I physically move the mouse on the 13.5" Macbook, no problem. If I switch virtual screens, the Screen Sharing goes to normal processing.
I see an appearance of a compute-bound thread on the Screen Sharing client. It takes 100% CPU on one thread, the machine as a whole is 12.5% busy (the performance monitor considers all 8 threads as equal when in fact, they are not).
A few more pieces of information. The VMWare client ends up having a lot of overlapping windows with a lot of changing graphics. My mouse runs into problems especially when it is overlaying a changing plot (Perfmon running in Windows 7, or updating email client). It does turn out that VMWare has a "native" VNC server built-in and I tried to connect to the virtual screen using the Screen Sharing Client on the machine with computing problem and voila!, no problem. I end up having a Screen Sharing Client running native running screen (supposed to be VNC, but I have not verified that) sharing protocol on a virtual screen that is NOT the VMWare virtual screen and a separate session using actual VNC protocol using the VMWare VNC server. It works perfectly fine.
If I may hazard a guess, I think I know what the bug is, or at least, what is the nature of the problem that I have. The rest of you may have a different bug. When I have difficulty, it is because I am on a window that suppresses the dock, both in remote virtual screen and on the local machine showing the screen. Two docks are suppressed, one remote, one local. Throw in overlapping windows with changing graphics in the overlapped windows and toss in a mouse on top of that. I think that the Screen Sharing is trying to refresh overlapping windows with mouse and going through the suppressed dock calculations and never converging on what the picture should be. The mouse ends up being the visible cue that shows the time frame for iterating the windows - flickers with a timeframe of greater than a second. That is far greater than the screen update time. It is totally compute bound with all the overlapping stuff that it is deconflicting. At least, that is what I think is going on.
Meanwhile, the VMWare VNC server appears to send out a single graphics context and causes the Screen Sharing client to converge to a picture. Note, the mouse appearance is very different when attaching to the VMWare VNC Server rather than the ScreenSharing native server. I see two mouse renderings, the virtual machine remote and a mouse rendering from my Screen Sharing client side. They are mostly in sync in position unless I move the mouse very quickly. If I use Screen Sharing client and server instead, I usually see only one mouse, the client side's mouse rendering.
I have a solution for my problem. It is similar to using a different VNC server/client pairing. I will use a VNC server for the systems giving me trouble that is not Screen Sharing Server exercising a probable bug in the Client (though, it could be a problem in the design of Screen Sharing itself).

Skype vdeo call and high cpu usage on Mac

Hello,
I have seen many posts around skype video call causing extremely high CPU usage which in turn causes a lot of heat and fan starts to go crazy. This does not seem to happen on Windows. I have trawled various forums and tried everything but to no avail.
Finally the workaround that worked for me was simple - during a call when CPU usage is going through the roof and the fans going crazy - just share your screen for a few seconds with the caller and then unshare. CPU usage dramatically falls off and stabilises at around 38% to 40%. I have noticed this my Macbook Pro (2013 2.3ghz, 16gb RAM) running Yosemite.
This is definitely a problem with Skype. Guys; please fix....

Did the sharing and unsharing of screen stabilise your CPU usage? I also tried deleting the Library/Caches/com.skype* directory and whilst it helped initially, in the long run it did not work. The only thing that worked for me was sreen share and unshare.
Personally I am just getting more and more disappointed with OS X. The way they have implemented HiDPI support with scaling (downscaling and then upscaling) is just insane and a lot of applications struggle. I am sure this is not the root cause of the high CPU usage issue for Skype. It's not long before I come off the Apple ecosystem altogether.

Opera and high cpu usage

Hello all!
I have this annoying problem with opera.
After 1-2 hours of running opera cpu usage jumps to about 60-80%. To stop this I have to close opera and restart it.
I mostly have about 30+ tabs opened, but this shouldn't affect the cpu usage. It didn't in the past. I used the opera-devel-qt4 (10.20_4744-1) package from AUR and now I switched back to the "default" opera (10.10-2) package.
This started some days ago, and i cannot find out what causes this.
Any suggestions?

I have no plugins running and killed the wrapper.
However it worked fine for the most time. I noticed opera has a higher usage than firefox. But now it's barely usable. Every 3-5 hours I have to stop and then restart opera. With the bundled version it's a little better. But it still freezes for some seconds with high cpu usage.

Firefox very slow and high cpu usage!! (all other browse slow too)

Sorry, I asked it in 'Newbie Corner' , but still no resolved. so I asked here.
Hi all,
when i open a website just as www.sohu.com, my firefox (3.0.3) hang on, then display the web page very slow , and slow scroll , firefox cpu usage nearly about 100.
I tried some sloution,like modify /etc/enviroment to set MOD_DISABLE_PANGO=1,
or disable 'tell me if a web site ...' in firefox security option.
but still slow.
some people says it's must because flash or some js.
but when i try it in windows or ubuntu, it very fast, not like in archlinux.
so i think some thing wrong in archlinux. I need your helps.
thank you.
p.s.
1. pacman is very fast (the speed of wget about 400k/s)
2. gnome web browser like firefox , slow and high cpu.
3. the list of output of 'locale' about 11 lines.
4. i have already set host name like wiki says.
5. the system is a new system

USB Devices Not Detected and High CPU Usage

Hello, I'm using arch on a Dell 1720 laptop.
I have some weird issues involving detection of USB devices.
When the laptop is on battery and I plug in a USB mouse the power flickers on and flickers off again; nothing in the logs/dmesg.
If I then connect the AC adapter the reconnect the mouse, the same happens, except the CPU usage hits 87%+ on one core.
Running
sudo rmmod ehci_hcd
solves the problem; the CPU usage drops and the mouse gets detected.
Subsequent attempts to hotplug USB devices does nothing, no high CPU and no Power.
Rebooting the computer is the only way to use USB devices at the moment.
usb-autosuspend is disabled in laptop-mode.
uname -a:
Linux MatSalleh 2.6.39-ck #1 SMP PREEMPT Sun Jun 5 18:30:30 EDT 2011 x86_64 Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz GenuineIntel GNU/Linux
The same happens with the stock kernel too
My kernel line in grub:
kernel /vmlinuz26-ck root=/dev/sda3 elevator=bfq ro resume=/dev/sda2
Any ideas?
Thanks,
Chris.

I highly doubt it's that, it was working fine on ubuntu just days before...

This one helps me to solve this problem
My USB devices don't even get detected, so that script won't work.
Last night I hibernated my computer after not using any USB devices, on resume, my CPU usage was 100%, removing the ehci_hcd module fixed it.
Any more ideas?
I'm tempted to build a vanilla kernel...

Weak performance and high cpu usage

I've been wondering for sometime now, how can some flash games run so laggy on my pc at the same time where i run DX and OpenGL games without any problem and smooth!
Whenever i play games in FB or any other site, i notice high cpu usage about 70-90% especially when i run them fullscreen (1152x864) and with effects enabled then my system kneals almost!!!!!! This is UNACCEPTABLE of course..
I also found an interesting article which i dought if it has been updated as it was supposed to, which is the following link: http://forums.adobe.com/message/5417983#5417983
I run Flash player on an Intel E5700 - Win XP sp3 - 4GB ram and an Nvidia GTX650.. for those who understand, such a system is in position to run flash games like an adult holds a baby in his arms... so either the hardware acceleration does not work or adobe has let this problem unresolved for years now as i have made an interesting research on this case before i come here.
For the records, i run flash games within Chrome since it's proved to be the most apropriate browser for videos and flash-shockwave games.. firefox comes 2nd to me and IE 8.....leave it unused better!
Even in 2006 up to today, people are facing high cpu usage and weak performance in flash apps no matter what pc they have, so who is to blame here?? Adobe ofc.
Is there anyone who has a solution to propose or has found somethin relevant to this case? Or should we wait a solution in 2020?

Mike M., i didn't give any load or credit on u, but Adobe, as i see you're not responsible for their mistakes or ignorance so i have nothin to ask from u, i have seen that u reply to ppl and good for u.
All i have to say to what u replied, is that, what if win xp reach the end of life? i mention a problem that remains for years now and is unresolved, or didn't they see that the previous years?since 2008 let's say!!!
I have noticed the same exactly behavior on newer OS and specifically tested on Win Vista 32-64 and Win 7 32-64 too..... it's EXACTLY the same behavior, so it's not OS dependant, i won't take any excuse for Adobe cause i have experienced their terrible work on flash-shockwave for too long.
It's their responsibility to solve it but they have chosen to ignore this and many other mistakes that users report weekly for years, their response is 2/10 solved... it's just disgusting. I dont' want to argue with anyone for Adobe's shake, they don't worth it.

Conky and high CPU usage

I originally posted this in the Newbie Corner, as I consider myself a newbie, but got no answers there and I think my issue is pretty kernel-HW-related, excuse me for re-posting.
I was editing an old peaceful Conky and it somewhen started making high use of the CPU (around 30-40% avg.). As I couldn't figure out where the problem was, took out every configuration line in the conky file and ended up with the few following lines, which are by themselves triggering the same high CPU usage. I don't have much experience with Conky, could anyone explain me if this behaviour would be expected from this simple code or is there something else?
Thank you.

Odd freezing up and high CPU usage reported

Occasionally, my system will become unstable and freeze up. Finder normally causes the problem and there is the spinning rainbow wheel of death. On a similar note, activity monitor reports 55% system CPU usage, when there is nothing listed that is using that much CPU, and, when this happens I am unable to shutdown, unless I hold down the power key. Any suggestions?

Mostly the output is from errors from google chrome, really meaningless. My system froze 2 times in the past 15 minutes, and i was using a USB drive, brand new. I have had issues with 3 USB drives overall, and what happens is that the system uses 55% CPU on an unregistered single core process, so it uses 100% of one core and the rest spills over to the other core. It is apparently a system process, no records of any issues in console... But when i killall Finder and attempt a manual reboot now command, it's stuck on the blue screen, and I would need to do a hard shutdown by holding down the power key in order to be able to use my computer. Sometimes it freaks out when i am copying something on the disk as well, BUT my entire system passes the Apple Hardware extended test, so i'm confused as to what my next option is to do. Reinstalls tend to be annoying and the problem presents itself even after reinstalling, and using different USB drives, and repartitioning the USB drives. This is all pointing to a software driver bug, or finder just *****

Connection Failed when File Sharing and High CPU Usage

I have a small wired network where a G5 Tower (10.5.8) has an external drive connected via FW800 set as shared so it can be accessed from a C2D iMac (10.6.4). This has been working great since it was setup in Feb.
Today the iMac was unable to access the G5. It didn't show either the Public folder on the G5 or the shared FW drive. When clicked it showed "Connection Failed." Immediately the G5 spun up to 100% CPU usage. Activity monitor showed AppleFileServer as the culprit, and when quit, resumed to normal usage.
Same happens when trying to access the G5 from a Mac Mini (10.5.8)
Once the iMac gave a warning of something like: "Failed to connect because there are too many users." Which is rubbish because no one was connected or could connect, and this was verified in the Sharing Pref Pane.
I've tried restarts, disk repairs off a boot disk, and enabling / renabling File Sharing. The G5 can connect to the other macs, and they to each other, just not to the G5.
Anyways, any help is much appreciated. Thank you.

So somehow I got the computers to connect to the G5 with file sharing. I went through a bunch of steps, and not really sure what worked.
I believe it had something to do with the 'Public' user folder only being listed in the file sharing pane, instead of the User folder. Why that would also stop the shared external drive from being seen, I'm not sure.

K8NGM2-FID problems: no usb and high cpu usage - HELP!

hi folks,
i've setup K8NGM2-FID inside an htpc with a clean install of mce 2005 (onboard video). For the past couple of days I've noticed a few things:
1) if the pc goes into standby (S3) and then wakes up, sometimes task manager shows a cpu usage of 50% (on the graph) but looking at the list of tasks (for all users) nothing is runing that high - in fact system idle process shows 98% (while the graph is still showing about 50%) and the system is a bit sluggish; reboot fixes this but it's getting really annoying. I've installed the latest AMD x2 driver. Sometimes it goes to 98-99% after waking up but that's been rare.
2) i've been getting a few BSODs lately, actually all started yesterday - 3 of them in a span of about 2 hours after insalling Nero. I'm going to try to figure out what is causing it that (proabably Nero - I hope since that's easy to undo) but what i've noticed is that when the system reboots after the blue screen, none of the USB devices work (i.e. keyboard, mouse, etc.). windows has to load, then I need to go in the back and unplug/replug the usb devices which then 'wakes' them up; this can get really annoying in a typical cramped home theater setup. software restarts seem to be good - ok hardware restarts are the problem. hooking things up to a usb hub has the same effect - i.e. I need to re-plug the hub to get them to work - it just means less things to plug/unplug.
has anyone else noticed this? help save my sanity - this is driving me crazy. since this is an mce setup, it goes into sleep and wakes up several times a day so the high cpu issue when it comes up really gets in the way of using the pc. btw. during high cpu times, no mce related function (record/watch/the shell itself) is running.
here's my setup:
K8NGM2-FID - boots up with 3 short beeps - I think it's 1 beep pause then 2 beeps
2 gigs kingston 3 CAS (2 x 1 GIG kit) pc3200 - boot screen shows it running at 400mhz in dual channel config
X2 3800+ stock fan/heatsink with silver 5 (runs around 35-38 idle - inside a silverstone 'stereo rack' case)
ms usb keyboard/mouse/mce remote
coolmax 550W power
3 140GB WD drives (ata 133 - not sata)
onboard video - framebuffer set to 128megs
latest (as of 2 days ago) nvidia and msi drivers - msi bios is the stock 3.0 (more on that later)
the bios settings are all default as far as I can tell.
pvr-150 tuner card
promise ata 100 card
nec 3500dvd
all running on mce 2005 with rollup 2 and all the updates windows could find
i haven't updated the bios because i've read about other folks having blue screen problems and the suggestion has been to up the voltage for the ram (I guess the default setup from MSI is lower than it should be) but apparently that option is missing from the 3.1 and later bioses? and reading the text file, it wasn't very apparent what the bios 3.1 was fixing other than a few cosmetic bootup texts. I'm planning to up the voltage later today.
anyhow, any suggestions short of throwing the entire pc out the door are welcomed.
thanks!

ok here's what I've found about the high cpu...
using process explorer, hardware interrups is taking all the cpu. i've tried to disable items one by one but nothing is working so far. what does work is if i choose scan for new hardware, cpu goes down to normal. standby and resume and cpu is up again. do the scan and it goes down again - without changing anything.
i've re-installed the graphic board driver, nvidia 430 drivers, sound driver. not sure what else to do. checked my drives and they are all properly master/slave set.
this is really getting crazy...anyone come across this?
i'm a bit hesitant to go to bios 3.1 since i've seen lots of posts about BSOD and i've just gotten rid of that.
thanks
thanks a bunch!

High number of threads and high CPU usage on a single instance

Without any apparent reason, in some moments of day the website reports an increment of the HTTP Queue Length from an average of 10/20 queued requests to 100/200 and more.
In that period of time the Average Response Time increases but the number of the requests on the website don't. Even increasing the instances it doesn't help to resolve the problem (maybe it just reduced it).
It seems that the problem is not related to the traffic on the site. This issue happens either when the traffic is high or low.
The autoscaling works well, we don't have peak of traffic but always a slow increasing of requests and the CPU is always below the 50% (memory too). The issue is resolved by the swap of the site and sometimes it's resolve by itself after a while.
What I discovered when the issue happens, is that there's an instance (just an instance only), that has an high number of threads and CPU usage on the W3WP.exe process and these values are above the mean than the other instances. Eg, instances are around
50/60 threads and 10/20% of CPU, the instance with the problem has 200 threads and 50/60% of CPU. If I kill the W3WP process on that instance the issue is resolved.
I monitored the HTTP requests, I tried the website extension "Diagnostics as service" but I can't discover anything that can help me to understand the problem. Of course, there are many requests that go in timeout but it is a consequences of a
unresponsive instance.
On the web hosting plan there are only two sites: the production site and its staging which is used for update of the production only and it's always sleeping. Plus, no webjobs are running on this site.
What can I do to gather useful information that can help me to understand the reason of this problem?
Thank you!

"Does the instance with the high counts receive more traffic than the other instances? Is it possible that the load balancer not
working the way it should be?"
How can I get that information? I can't see metrics for a specific instance
"Does it always happen to the first instance?"
I will check it better, but in the order given by the Processes panel it's the second instance which has the issue. The scaling is at 2 instances for the most part of the time (it's the minimum).
Maybe one time it was the 3th instance but I'm not sure, I'll give it more attention.
" How long do these moment last?"
The time can be 10 to 30 minutes, but I fix it as soon as I see the problem. It's not the down-scaling to resolve it because in these situations the CPU as well is high so the scaling holds or increases the number of instances.
"- How often do these moments occurs?"
It occurs quite often, 2/4 times a week.

ME3600X-24CX and high CPU usage due to Nile process

Hi,
if I insert SFP modules into ports CPU usage increases. Now I have 14SFP modules (mostly metalic ones) and the CPU is above 20% permanently. All of them used by Nile process. Which I understand is something which reads interface state and switches on/off the LED lights. I think that such a thing shouldn't eat 20+% of CPU power. There must be something wrong with the process.
As a result the switch is not able to respond to ICMP packets reliably (smokeping graph is very noisy). And I can imagine that other CPU tasks (BGP etc) could be affected too (but maybe the NILE process has lower priority).
Verified on another ME3600X-24CX and checked with various SFP modules.
Regards
Dalibor Toman

I tried to solve the problem by opening a ticket with our vendor. But because Cisco doesn't treat the problem as a bug there is no real solution but a workaround only. We increased the NILE process poll period using this command:
test platform link_poll set_interval 80
The CPU usage lowered significantly. And the response time on smokeping graph is slightly better too (less higher response time peaks on the graph)
I have attached a graph of CPU usage for last 2 years. During may 2014 we replaced Cisco 3650G with the ME3600X and cpu usage went up. Next month we reconfigured the poll period and cpu went lower. During november we moved about 8 links to another device so the CPU usage lowered again.

Socket and high cpu usage

Hi, am I using a multithreaded chat system: so a server and clients which can connect to the server.
The cpu usage is too high...probably because:
- The server is waiting for connections all the time
- The socket.getInputStream is continuously waiting for data
Running the server with: java -Xprof Server gives:
98% serversocket listening
82% socket.getInputStream reading
So probably the inputstream does this continuously:
is there data? no
is there data? no
is there data? no
and so on.
How can I decrease the cpu usage?

Are you sure that the inputstream doesn't look for
data?
So this doesn't happen:
is there data? no
is there data? no
is there data? no
is there data? no
No other threads are running. Just for each connecting
client a new Thread
Well, this does happen, but not in your program. This check
is usually done at OS level or hardware level.
BTW, how do you know that CPU usage is too high? Which tool
did you use to see the CPU usage?

Newbie having problems with noisy fan and high CPU usage in Activity Monitor

I am new to the world of Apple and have got my hands on a hand-me-down PowerBook G4 version 10.4.11. It works fairly well for everything but the Internet.
One of the first symptoms i noticed was that watching stuff on youtube was slow and jumped a lot. I checked a few things out and looked the CPU usage in activity monitor and this was about 80% to 100% when on youtube or even moving from page to page. I'e tried loads of stuff including repairing disk permissions, emptying caches and relaunching finder when the preferences file is on the desktop (not really sure what that was supposed to do).
The next thing I discovered was that if i disconnected the laptop from the mains and played youtube and some other applications the whole thing would go into sleep mode very quickly. I have got temperature monitor downloaded now although I already know it is getting very hot.
PS when it heats up the fan turns on because I can hear a whirring sound...
Would really appreciate some insight into this as it seems to be a good runner otherwise.
PS2 I have loads of free space left in the disk usage tab in activity monitor.
Big thank you in advance

Virtually no G4s are dealing well with web video anymore. The video technology used by modern developers puts a huge strain on a G4 processor. As this a choice made by coders, there is not much you can do about it. Some people suggest adding RAM but the effect is marginal considering it's the processor that's taxed.
Notebooks get hot. The fans in my 1Ghz 17-inch PowerBook from 2003 kick in between 130 and 140°F. The danger point is not until in the vicinity of 100F so don't sweat it to much. Make sure you do not cover the case bottom by setting the computer on a thick cloth placemat, pillow or other bedding item, or on your lap without a lapboard. The bootom of the case is part of the heat dissipation system and needs air under it to work
A lot of PowerBooks have, by now, lost some or all of their "feet" that gve a little space under the case. Don't bother looking for official replacements--get the silicone door/drawer bumpers from the hardware store that stick on. I found some about 3/16" thick that let more air under my PB thatn the mostly missing originals.
The next thing I discovered was that if i disconnected the laptop from the mains and played youtube and some other applications the whole thing would go into sleep mode very quickly
Your battery is likely dead from old age. Batteries only last about 2-3 years. You are seeing a sign of the battery lacking sufficient remaining capacity to run the computer. Get this utility:
