Slow youtube, high CPU usage
Hey. My girlfriend has a 2-year-old Toshiba Satellite C670D-10C. It's been somewhat slow from the start but it really started to bug me a couple of months ago. I did the obvious virus-checks and spyware-checks with numerous programs and came up with nada. I uninstalled all the unneccessary programs and disabled the quite a many programs on startup.
The cpu-usage goes nuts whenever I start opera or firefox. Now it's 100% for example. Also the memory usage is around 60 %. I can't understand what's behind this. This thing hasn't got much ram (3 g), but it still shouldn't run this bad. It's been to a store, where they really didn't do much to it and asked for 100 euros. Said that it's just intrisically slow.
Now when I look at the processes tab, I see firefox hogging almost 600 000 kt and a svchost-process, that's taking 91 000 kt. This laptop has never been fast, but it got a lot worse about half a year ago. Shoud I reboot the system?
Solved!
Go to Solution.
From looking at the specs, this system is running the AMD E-240. From my work on C655D's, I have dealt with several E-300 and E-350's. The E-300 is sluggish enough, and benchmarks much higher than the E-240.
The systems with these AMD processors need to run with minimal programs running in the background. I am currently fixing up a C655D-S5518, which has the E-300. I use a program like CCleaner or Glary Utilities, to disable startup items and processes, to help improve system performance. Here's a list of items that I disable from startup on these systems(you may or may not have these):
- anything Adobe
- anything Java
- anything Apple
- bulletin board
- service station
- reeltime
- applace
- book place
I also get rid of anything like "weatherbug", news tickers, etc.
This helps the system start up faster, and run smoother. Just to test, I upgraded one E-300 system from a HDD to SSD. The performance improvement was decent, but the processor would still max out at times, causing lag.

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 systemhttp://wiki.archlinux.org/index.php/For … Bumping.27 ??

Slow computer -- High CPU usage
OK here's the specs of my computer:
G4 933Mhz, 1.5Gb Ram 80Gb internal HD, but booting from a 250Gb external firewire
Now the problem. My CPU usage in Activity monitor gets close to 100% system usage after a few hours even if I don't have more than a couple of programs running. I do notice that pmTool and Kernel_task are eating up the majority of the CPU cycles though. When I boot from the internal it happens as well, but to a much lesser extent.
I did an archive and install of the 10.4 on the firewire and the problem still exists. Current system is 10.4.8.
Any ideas how to stop this? It appears that this problem started about a month ago and the only piece of software that's been updated since then has been Skype and Second Life.
EricI have been looking at applications that might be eating up the processor and the only one that's doing it is the System right now. Restarting seems to help. I've been running for a couple of hours since the last restart and my current stats are 16% User and about 20%-60% System. pmTool seems to be the hog at the moment at 22.5% Kernel_task is only at about 6% though.
Any more information you'd like that could help to diagnose the problem let me know and I'll provide it. here's the current console log if that might help:

Opening signed PDF's is slow + generates high CPU usage
Dear,
I'm using the latest version 11.0.06. Normal PDF's open quick. PDF's signed with a signature take about 5 seconds to open, a big difference. I'm running Windows 8.1 but the issue is the same on Windows 7 SP1 (fully patched systems). When the PDF is opening, the CPU spikes to 30 or 50%. Since I'm administering some virtual PC's also (with less performant virtual CPU's then physical CPU's), the PDF's take even 8 seconds to open in this environment. The environment is quite optimized with settings like disabling update checks,...
Some things I tried :
- Disable antivirus (no difference)
- Disable messages when I launch / Don't show messages while viewing (in General preferences)
- Disable check signatures / signature revocation
- Disable protected mode at startup
Another test I did is installing foxit reader. This PDF reader opens the signed PDF's as quick a normal PDF's and evening quicker then Adobe reader is opening normal PDF's.
Any advice on further troubleshooting steps ? I would prefer to stay using Adobe reader instead of migrating to another software.
Best regards / thanks in advance for your help,
WimHi Deepak,
Thanks for your feedback. Both on Windows 7 and 8.1, this value doesn't exist. This also describes another issue but it was worth trying anyway.
You can test on your own system by using this example pdf : http://blogs.adobe.com/security/SampleSignedPDFDocument.pdf
Best regards,

Unusually High CPU usage by almost all programs
I have a BIG problem with my computer. It start over a week ago and ever since, I've been trying to fix it. The problem is that almost all programs I use takes up 100% of my CPU usage. The only thing that doesn't are window's program but they also take up a lot of CPU usage. It is not the usual 1-3 sec of high CPU usage that all programs use. It is high CPU usage for a long period of time. A Youtube video causes my CPU to go to 100% just by playing it. Also, scans, surfing the web and other things cause it to go up. My computer runs really slow because of this. It is about 2-3 times slower. This is strange because my computer would rarely ever go over 60% for longer than 5 seconds. The memory amount taken up from my programs are not unusual. Its just that CPU part is way to high. I am un-able to play a game and open a web browser without massive lag on both programs. I have done everything I can. I did a restore for a day before this happened and it didn't work. I scanned for viruses with McAfee Microsoft essentials and Ad-ware antivirus and removed all threats. I have clean my computer with CCleaner and Advanced system care. I have scanned for spyware with spybot S&D, Superantispyware. I have checked for malware with Malewarebytes. But the problem is not solved. I really need the help. If you want me to download something to scan my computer I'm up for it because currently, I'm desperate.
Another thing. I have an Intel Core 2 Quad CPU. But, in msconfig, I cannot select 4 processors in advance options in the boot section. I only shows 1 for some reason. I could really use the help.

Since 10.4.6 Update: "ATSServer" with high CPU-usage when opening PDFs
Since I've updated to 10.4.6 my system is very slow when I open PDFs (in "Preview" or "Acrobat").
This is caused by the process "ATSServer" which goes through every file in "~/Library/Fonts" (I have over 4.800 files there - but just a view are activated by "FontBook") and so it takes very high CPU-usage.
I didn't have this problem bevore the update and I didn't make any changes on my font settings.
I've cleaned the font cache, but it doesn't help.
Any ideas?
Ciao

PowerBook G4 17'' 1.67 GHz Mac OS X (10.4.6)
PowerBook G4 17'' 1.67 GHz Mac OS X (10.4.6)I haven't noticed any change myself, Dan, but I have the 2 GHz model.
One thing I HAVE noticed though after OS updates is that they can often result in a fair amount of file and free space fragmentation immediately after installation. OSX's routines will deal with fragmentation of small files , but not of large ones (over 20 Meg), and it won't deal very effectively with free space fragmentation. If your HD is getting full this can cause significant slowdowns, especially where video is involved.
You should also run DiskUtility and check for any directory and permissions issues.

High CPU Usage On client application when upgrade remote SQL database
Hi,
Is anyone here encountered very high CPU usage after upgraded the database from SQL 2005 to SQL 2012? Following describes my issue.
I have my client application running on Windows 7 that access to central database (SQL 2005) on Windows server 2003 using ODBC connection, this client application basically query data and perform data insert and update. There are a number of this similar
clients connected to the database.
Due to slowness of the database server, company decided to upgrade the database server to SQL 2012 and also new hardware runing Windows Server 2012. There is no change on the client application and client hardware and the client application still using the
same ODBC connection to query, insert or update the new database server.
The problem I am now experiencing now is that my client PC where my client application running the CPU usage is very high almost hitting 100% when accessing to the central database. I am also noticed this program lsass.exe that utilized almost 40-50% of
the CPU time when client application accessing the central database.
Is anyone here know, why client PC CPU usage 100% when access to upgraded SQL 2012 database? What is lsass.exe program doing, it only appear when accessing to database server. How to reduce the CPU usage on client?
Thanks.
Chee Wee.Hello,
After upgrading, please rebuild indexes and update statistics on the databases.

High cpu usage when using flash player
Hi,
Just updated to Mavericks and now I'm having very high cpu usage while watching streams using flash player. CPU usage is somewhere around 110% and after a moment the stream starts to lag and fps is slowing down. I also tried using Chrome but with no difference. Flash player is the newest version 11.9.900.117.
Any ideas on how to fix this?i think its the best to hit the report a problem button in safari, since its appears since i updated safari to 5.1.4! maybe they make a additional update

High CPU usage (more than 100%) while running video applications
Hello everyone,
I desperately need help with this.
I have a late 2007 White Macbook running Mac OS X 10.6.8 :
Model Name: MacBook
Model Identifier: MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 3 GB
Bus Speed: 667 MHz
The issue that I am having is, whenever I play a video (Netflix/Silverlight player, YouTube, Skype, etc.) the CPU usage shoots up above 100% and the video or the video chat becomes VERY choppy. It becomes impossible to keep going once that starts. Originally I had 1Gb RAM (512 + 512) ... then I upgraded to (1GB + 512mb) ... it was fine for about a year and then started chocking on memory... so recently I made it (1GB +2GB) and that's when this high CPU usage thing started (according to my knowledge)
I have had this machine since last 4 years and its very dear to me. I dont wanna buy a new one. I will really appreciate if someone could help.I am spending sleepless nights, researching for a fix. From what I found so far, a considerable amount of people were able to fix this issue by simple cleaning the insides of their machines using air dusters, especially the fans. I don't know how cleaning would help with CPU utilization, but by interpolation, I feel it's worth a try. At least it will be clean, if not perfectly functional. lol
Now the next big challenge ahead of me is getting the screws on my Macbook open. I was following the Fan Repair Guide on ifixit.com. I went and got the #00 Phillips screwdriver as suggested in the guide... came home and found out the screwdriver is too big.... went back got a #0000 Phillips (I also found out that screwdrivers with same number might be of different sizes in different stores)... got a couple of screws out and then--- another road-block!! there are a few extremely tiny Phillips screws on my macbook. Now I am hunting for the smallest Phillips screwdriver in the world. Hopefully, I will find it in some watch repair or eye-glasses repair kit in a store such as CVS or Walgreens... aaaah... this is sooo frustrating!!! I just want to get his done so that I can check it off the list of probable solutions that I want to try. Will update here if this works.
From what you say, I think that the Silverlight upgrade might be the culprit in my case too. But the effect is there also for Youtube, Skype , or any other Video/Graphics intensive application that I use. Although, Silverlight/Netflix performs the worst among all the apps.
I love my Macbook... don't want to part with it. -
IMac Air High CPU Usage while Idle / Kernel Issues
Hello,
I am attempting to repair an MacBook Air that a customer spilled a small amount of orange juice into. I have completely taken the unit apart and thoroughly cleaned the motherboard and all components. There doesn't appear to be any physical damage done from the liquid. The problem is that the customer claims that since the spill happened the computer runs "very slow" and the CPU usage is very high even while completely idle (Bounces between 60%-80%). Being versed primarily in Windows PC Repair I am looking to post some diagnostic logs on here and maybe get some help from someone who knows what they are looking at. The customer took the machine to the Apple Store and they told them it had a "kernel problem" and would need a new Logic Board. Any help would be greatly appreciated, I just need to know what diagnostic reports I need to post to get this ball rolling... Thank you for your time.

This is a spin off from another thread which started off as slow inserts. But what actaully happens is every insert is preceded by select it turned out that the select was slow.
We have a multi-tier web application conencting to the DB using connection pool and inserting about a 100000 records in a table. To isolate the issue I wrote a PL/SQL which does the same thing.
This problem happens every time the schema is recreated or the table dropped and created again and we start inserting. When the table is empty, the selects choose a full table scan but as the records are inserted it continues to use the same even though after a few thousands of rows I run stats. But as its running if gather stats and flush the shared pool, it picks up the new plan using the indexes and immediately gets faster.
But in either case, full tablescan being slow after a few thousands of rows or using the index and getting much faster. Or me just doing the same select and no inserts on a table with 100000 rows, the CPU seems to be pegged to the core.
The code snipped repeated again
DECLARE
uname NVARCHAR2 (60);
primid NVARCHAR2 (60);
num NUMBER;
BEGIN
FOR i IN 1 .. 100000
LOOP
uname := DBMS_RANDOM.STRING ('x', 20);
primid := DBMS_RANDOM.STRING ('x', 30);
DBMS_OUTPUT.put_line (uname || ' ==> ' || primid);
SELECT COUNT (*)
INTO num
FROM TEST
WHERE ID = 0
AND (primid = primid OR UPPER (username) = uname OR uiname = uname
AND (deldate IS NULL)
ORDER BY TIME DESC;
INSERT INTO TEST
VALUES (0, uname, uname, 1, uname, primid);
IF MOD (i, 200) = 0
THEN
COMMIT;
DBMS_OUTPUT.put_line ('Commited');
END IF;
END LOOP;
END;This is the original thread
Re: Slow insertsMaybe if you post the actual code, or a code as similar to the actual code, the users of this forum may provide you with more appropriate suggestions.
Personally, I would like to understand what is the logic behind, so I can provide you with better advices.
Anyway, let's focus on the code that we currently have on the table.
Why your CPU goes high?
- Huge amount of LIOs produced by SELECT statement which is executed 100000 times.
- Usage of single-row / aggregate functions
- You mentioned you have some indexes created on table TEST. Index maintenance consumes some CPU as well.
Let's focus on the SELECT statement, since it is the most important reason for having high number of LIOs thus having high CPU usage.
I built a test case using the query you provided, with one difference, I named TEST table columns as COL1, COL2, etc. And instead of 100,000 cycles, I did 10,000
declare
uname varchar2(60);
pname varchar2(60);
num number(5);
begin
for i in 1..10000 loop
uname:=dbms_random.string('x',30);
pname:=dbms_random.string('x',20);
select count(1)
into num
from test
where col1=0
and (col2=uname or upper(col5)=pname or col3=uname)
and col4 is not null;
insert into test
values (0,uname,pname,1,uname,uname);
if mod(i,200)=0 then
commit;
end if;
end loop;
end;When I run 10046 trace and made tkprof report, I got the following for the SELECT part:
SELECT COUNT(1)
FROM
TEST WHERE COL1=0 AND (COL2=:B1 OR UPPER(COL5)=:B2 OR COL3=:B1 ) AND COL4 IS
NOT NULL
call count cpu elapsed disk query current rows
Parse 2 0.00 0.00 0 0 0 0
Execute 10050 0.48 0.43 0 0 50 0
Fetch 10000 94.07 94.37 0 2910664 2 10000
total 20052 94.56 94.80 0 2910664 52 10000As you can see, tkprof report indicated high CPU usage and 2,910,664 LIO calls.
The execution plan (I didn't include that part) indicated FULL TABLE scan on table TEST was used.
At this point the goal should be to reduce the number of LIO calls.
For this purpose I created the following indexes:
TEST_IDX1 on TEST(col2)
TEST_IDX2 on TEST(col3)
TEST_IDX3 on TEST(upper(col5)) - a Function Based Index
Let's forget about the statistics at this moment.
I will use index_combine hint in the SELECT statement to make CBO to try every index combination for listed indexes (B-Tree) and make bitmap conversion.
The new code looks like this
declare
uname varchar2(60);
pname varchar2(60);
num number(5);
begin
for i in 1..10000 loop
uname:=dbms_random.string('x',30);
pname:=dbms_random.string('x',20);
select /*+ index_combine(test test_idx1 test_idx2 test_idx3) */ count(1)
into num
from test
where col1=0
and (col2=uname or upper(col5)=pname or col3=uname)
and col4 is not null;
insert into test
values (0,uname,pname,1,uname,uname);
if mod(i,200)=0 then
commit;
end if;
end loop;
end;After running 10046 trace and creating tkprof report, I got the following result:
SELECT /*+ index_combine(test test_idx1 test_idx2 test_idx3) */ COUNT(1)
FROM
TEST WHERE COL1=0 AND (COL2=:B1 OR UPPER(COL5)=:B2 OR COL3=:B1 ) AND COL4 IS
NOT NULL

The second code completed in few seconds compared to the previous one which needed about 100 seconds to complete.
Please be aware that this is just an example of tuning the code that you provided.
This solution might not be suitable for your actual code, since we don't have any information about it. That's why it is important to give us as much information as you could, so you can get the most appropriate answer.
If the test code is similar to the actual one, you should focus on reducing LIOs calls.
In order to achieve it, you may want to use hints to force an index to be used.

High CPU Usage with Flash Player 11
I am not sure what the problem is but ever since I had those issues I went back to flash archive and installed a previous version that did not come with the flash plug in and I never had any problem with it since I am currently using the Adobe flash version 10 plug in with an adobe flash player active X. and I find out it was the new flash plug in that is the issue it suck all your ram. If you get some people who is having the same issues where flash player is duplicating and eating all their ram then ask them to try the version 10 plug in with the flash 11 active x it will work fine. I tried to run the version 10 flash as a complete set but some dynamic site that plays videos require a later version of flash active x to work and will be asking for an update however by keeping the flash 10 plug in there won't be any other issues. Adobe need to find out what is wrong with the new flash plug in and run a comparison with the flash 10 plug in. I hope this will help some user to get over the issues that made my online experience a nightmare for a while too.
The best way to get a resolution is to address your individual issue. Your complaint is that RAM usage is high, which is unrelated to the thread from the guy on Mac that was seeing High CPU usage on high definition video.
In order to fix the issue that you're describing, we need to be able to reproduce it. Please provide the information below, and the results of the basic troubleshooting steps as you work through them. This will help us narrow down the root-cause, and allow us to find comparable hardware in our compatibility lab to reproduce the issue with.
Basic Troubleshooting Info
To help troubleshoot we'll need the following system information:
- Operating system
- Browser
- Flash Player version - http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
- Antivirus/Anti-Malware software and versions
The first step is to work through the video troubleshooting guide for your operating system, here:
- Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html
- Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.htm
When reporting issues with video or audio, it's also helpful to get your system hardware and driver details. Instructions for finding this information can be found here:
- Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Windows_users
- Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Mac_OS_users
Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player. I recommend trying both of the links below to see how they perform. If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing. You can verify this by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the menu.

Microsoft Office 2004 -- extremely high cpu usage and virtual ram
hi,
when i use office it causes a very high cpu usage even when its in idle mode.
i am unable to work with it, because its extremely slow.
does anyone have same experiences?
thanks for your help!
mbp 2.0 1,5gb ram 80gb hdd Mac OS X (10.4.7)I am able to work OK with office, I'm using the 'old version' Microsoft Office v.X, not much details in the About Box, just listed as MSoft Word/Excel/etc for Mac service release 1.
I get the occasional crash, and I have seen Word in particular use 90% of a single core and amazingly large virtual memory usage, gigabytes sometimes, but eventually the document gets printed.
It shows how useful the dual core (or quad) cpu approach is!
One cpu for Word to print, and one cpu to run the rest of my applications/life!
I still use this old office rather than re-booting into Window§ for whatever is the latest version of office.
Doing some playing with a similar one page document in Office v.X and Pages 2.01, I get Word using about 25% of a core , Pages using 5%, - whilst editing; Intel native Pages has 20% of a core and 80MB ram 480 virtual whilst printing, Word has about 100% of a core and 65MB ram 650 virtual whilst printing, but it is a powerPC code so Rosetta is in there somewhere.
check Activity Monitor or other apps/widgets for some parasitic processes? have fun!
many Macs 512k -> MacBool Pro 2GHz 1GB ram Mac OS X (10.4.7) Yes, I have Key Lime -

We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high.
This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure.
Below I provided some outputs that might help to diagnose it
Thanks

I was aware of the many ACLs however we used to have the same ACLs in a previous 3750G stack about 2 weeks ago and we never had this issue. I agree I need to optimize them and do somehing because it is reaching its max before the CPU starts processing them but I am not certain this is what is causing the issue.
Nikolay,
I am trying to understand "interrupts" with the analysis of the outputs I posted. Here is another output deom the link you provided. Please post your thoughts if you can.
This switch also serves as a gateway(L3 role) for many systems. Would it make sense to offload that responsability from this switch and let an actual router do it?
Thanks
Johnny
