Numbers 09 version 2.1 pauses having high CPU useage

I was running numbers 09 original version on 10.6.8 OS without any problems.  I updated to OS X 10.10.1  and numbers stated having problems. It would start running slow only after about 30 seconds of data input.  the CPU usage would jump up to 97-98% for the numbers program.  So I then updated numbers(still on 09) to 2.1  with all the lasted patches. Still having problems. I started a brand new spreadsheet with 4 column and no functions simple data: date, 2 text fields, and a cost field in dollars.   Same slow problems.  I can take 30 seconds just to input 1 field.  I will type ahead 1-2 columns at a time, and slowly the computer will fill in the fields from the keyboard buffer.
My system is a MacBook Pro, 13" early 2011 (version 8.1) came with 4GB ram and I still have 85GB left on my hard drive.  I notice that numbers was having to swap with nothing else loaded. so I updated my system have 8GB of new ram.  Numbers no longer swaps, but still runs slow.  Right after I tested this I put in a 480GB SSD  drive in the system. The system is like greased lighting now, EXCEPT WITH NUMBERS.  Number is still exhibiting the same symptoms.  After starting numbers and adding data to just one cell,   Activity monitor shows.
CPU 90%
Context switches 455367
Faults 96270
Machine calls 872945
Unix System Calls: 87191
During the time it took me to enter the 5 pieces of previous data, numbers used up 31.14 seconds of CPU time sitting idle after only 1 data field entry.
Thanks,
Bob

Thank you for this very helpful tip, Hiroto and Jerrold.
Bob, I was having the exact same problem. I came here to post a question for help. I would be typing along in a cell, then suddenly Numbers would have a huge lag/delay. I would finish typing about 5 seconds before the text was showing up on screen
I even went to Genius bar thinking something was wrong. What did they do? Reinstalled Yosemite, saw the Numbers problem still persisting and said, well its probably time to update to the latest version (3.5.2).
All I needed was to be on the most recent version before the newest iWork suite came out. Thank you so much for the helpful link. After installing it, Numbers 2.3 is cruising along on my trusty 2010 8gb MBP.
Thank you again!

  • Clamd high CPU useage

    I have an Intel Xserve running 10.4.11
    I followed Alex's tutorials some months back and upgraded clamav, amavisd and spamassassin.
    All has been working well and I have been pleased with the performance.
    However I decided approx 6 weeks ago to move from using clamscan to clamd.
    On and off I have been getting exceptionally high CPU useage from clamd which requires me to kill off the clamd process as everything almost grinds to a halt.
    I initially put it down to using Carbon Copy Cloner at night, but it has been getting more frequent during the day to the point where mail was just being queued.
    I killed clamd again
    ran
    sudo /bin/launchctl unload /System/Library/LaunchDaemons/org.amavis.amavisd.plist
    sudo /bin/launchctl load /System/Library/LaunchDaemons/org.amavis.amavisd.plist
    but then all my incoming mail started going deferred
    so I again reloaded amavisd.plist
    then ran postsuper -r ALL, to requeue all the mail. This worked for a few minutes then clamd started going high CPU again.
    Also in logs I started seeing in mail.log
    Mar 25 12:30:50 fileserver postfix/smtp[147]: 502232589239: to=<[email protected]>, relay=127.0.0.1[127.0.0.1], delay=2616, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.5.0 Error in processing, id=00791-05, virus_scan FAILED: virus_scan: ALL VIRUS SCANNERS FAILED: Clam Antivirus-clamd av-scanner FAILED: CODE(0x1801270) Too many retries to talk to /tmp/clamd (Can't connect to UNIX socket /tmp/clamd: Connection refused) at (eval 51) line 310. at (eval 51) line 511.; ClamAV-clamscan av-scanner FAILED: /usr/local/bin/clamscan DIED on signal 11 (000b) at (eval 51) line 511. (in reply to end of DATA command))
    So I commented out the entry for using clamd in /etc/amavisd.conf
    and rolled back to previous version of clamv.
    I am now getting mail in, and although very brief high clamscan usage it is working, the queue has been cleared.
    But now I am getting no logging in anything apart from one file, /var/log/asl.log.76
    this has thousands of entries
    [Time 2008.03.24 22:08:47 UTC] [Facility local6] [Sender clamd] [PID 18032] [Message accept() failed: Too many open files;] [Level 3] [UID -2] [GID -2] [Host fileserver]
    syslogd is also running very high CPU.
    Has anyone any ideas what caused my initial problems and what I may have done now to break the logging. ???

    Thanks Alex
    will schedule downtime to upgrade.
    update
    Reboot, again, of server cleared my logs problem (what a popular person I am )

  • Latest flashplayer not work well, even the early version in 11x and has high CPU usage

    why is it that flashplayer 11x always has  a High CPU Usage? detected by NOrton Antivirus

    you can't rely on norton antivirus.
    but if you check your active processes and directly confirm a problem with flash player 11+, uninstall your current flash player (http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html or http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html) and install an older version:  http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html

  • High CPU useage when more than 30 sessions logout/login

    Hi guys,
    I got this problem for a long time.
    Environment : RAC 10.2.0.5 . Oracle enterprise linux 4.8. Java B2C application with dbcp and oc4j dirver.
    Server type:Dell R815. 48 cpus 128 G MEM for each node.
    Here's many of web application's connect to database and when one of them is down it will restart soon and try to connect to database again.Each one will try to get 50 connections concurrently in the first time.
    So , when it happens ,the cpu useage of sys% will grow to more than 70 ,80 ,90% every time.
    BTW, it also happens in more than 30 logout concurrently.
    Could any one tell me what's the problem is ?
    Thank you very much.

    The task of creating a connection and session has to be serialised, and if you start a number of logon or logoff attempts simultaneously you can end up with a storm of activity on the relevant latches that has serious knockon effects. I am a little surprised that you're seeing this with only 30 - 50 connections, but possibly you only have a couple of CPUs.
    I made some comments about this on another thread some time ago: Re: Overhead of having high value of processes (or sessions) init parameter
    It's possible that you can configure the application server to limit the rate at which it tries to create or terminate connection - e.g. there may be configuration settings to say things like: "create no more than 5 at a time", "wait one second between disconnections". (Oracle has introduced some parameters relating to logoff storms - but perhaps they don't work in your version).

  • I keep getting a box that pops up saying "High CPU useage with Firefox". What do I do?

    Sometimes a box pops up saying "High CPU usage with Firefox".
    I'm not sure what to do or if this is harming my laptop.

    Well i tried the Microsoft Malware and everything is fine on this end and you are still crashing on me so with that said,i am giving you one more day to resolve this issue if i still get crashes from you i am sorry to say i will have to try another company as my browser and see if i have an issue with them if i don't,i will not be reinstalling Firefox again if i do,then it may be another issue so i will have to see but i have no Malware here but thank you for your response anyway...

  • Why do I keep getting a Norton AV pop up message "High CPU useage for plug in container on Firefox"?

    Norton keeps giving me a lower right hand pop up comment “High CPU usage for plug in container on Firefox." Is there something I need to set to fix this? Should I be concerned? Sometimes this occurs with no other application running.

    IMO, the detection threshold is set too low in that Norton app. Contact Norton support to find out how to set it higher, or how to turn it off.
    Or quit using Norton. ''I hate the garbage they sell. IMO, it is good for one thing, making money for retailer's and for helping PC techs make money fixing what it does to PC's their customers bring in for repairs.''

    This so called liquid damage that they are reffering
    to probably occured when I was working and had my
    computer on the desk...someone must have been
    drinking a coke cause when I came back there was a
    coke can on its side, but not exactly very close to
    the computer, and the liquid had seeped underneath
    the machine. When I picked the mac up there was
    liquid on the bottom of it, but only because those
    little useless rubber standoffs they put on the
    bottom of these Macbook Pro's was not high enough to
    be above the thickness of a water based liquid as it
    runs across a desk. At that point I promptly had
    unplugged the battery from my computer and the power
    cable and dried it all off. From that day no NEW
    problems had surfaced, the battery and heat issue
    had already existed.I didn't expect that any should
    because the liquid had only reached the bottom side
    of the computer and it was shut off quickly.
    Where was your desk?
    I think you should find the drinker/spiller of the coke.
    Getting electronics wet usually kils them, they aren't made water proof or even resistant.
    Logic board+super drive+batery=$1200 probably not far off.
    Some one owes you 1200 cokes and IMHO it is not Apple.

    The kernel is using excessive processor cycles. Below are some possible causes for the condition.
    Throttling
    When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
    ☞ a buildup of dust on the logic board
    ☞ high ambient temperature
    ☞ a worn-out or faulty battery in a portable
    ☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
    Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
    If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
    Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
    If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
    Installed software
    User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
    Corrupt NVRAM or SMC data
    Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
    External display
    Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

  • High CPU Usage on Cisco 3845

    Hi all,
    I'm having high CPU usage with one of my Cisco 3845.
    It works as an IP-IP Gateway and the CPU is quite high when the total number of calls only around 100-200 calls.
    I check the CPU usage with "show process cpu sort" and it looks like there are some "hidden" processes that consuming CPU.
    For example, 41% is total CPU, 25% is due to interrups, so CPU utilization on process level = 41 - 25 = 16%.
    But as showed below, processes don't consume that much CPU, only around 7% ???
    Please help to advise on this case. Any help is highly appreciated..
    Thank you.

    Has this been something that just recently started happening, or have you had this issue for a while?  Have you installed any new programs recently?
    You may want to download Glary Utilities, which is a free software(they will ask you if you want to go Pro, just say no, the free version works very well).  There is a module for startup manager.  You can go in and disable stuff that starts with the computer.  I would advise unchecking adobe, java, quicktime, printers, etc.  Anything that doesn't REALLY need to start with the computer.  The nice thing with Glary is that you can restart the computer, and if you find that you need one of the programs to start with windows, you can go back in and enable it again.
    The Celeron 925 processor in your computer is a decent entry level processor, but if there are too many programs running in the background, it can bog down quick.  I would also recommend downloading and running Malwarebytes Anti-malware, to be sure that there is nothing malicous running in the background.

  • High CPU usage on select

    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 inserts

    Maybe 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

          0       INDEX RANGE SCAN TEST_IDX3 (cr=19943 pr=1 pw=0 time=107200 us)(object id 52990)As you can see the number of LIO calls fallen dramatically. Also CPU time is significantly less.
    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 on router

    Hello, 
    I have got an issue with one of my routers having high CPU. Could someone please guide me in troubleshooting high CPU. What I should be checking on the router and what could be the cause of high CPU. 
    Thanks

    Hi, 
    There could be many reasons for high CPU. For high CPU on the router it could be process causing the high CPU or traffic (interrupts). Therefore first thing is to check if the CPU is being caused by some process or it is interrupts. 
    Few checks that you could quickly do on the router. 
    1. Show proc cpu sorted 5sec | ex 0.00 << This will confirm if there is process involved or interrupt.
    2. Show stacks >> Any recent crash happened
    3. Show ip traffic >> Any high amount of traffic which you think causing the issues. 
    4. Check if there is any debug running on the router. 
    5. Show interface switching >> Check if the how packets are being process. 
    Below document would be helpful in isolating the issue.

    106023, 106100, 106004
    TCP Out-of-Order packet buffer full (tcp-buffer-full)                     1949
    TCP Out-of-Order packet buffer full:
    This counter is incremented and the packet is dropped when appliance receives an
    out-of-order TCP packet on a connection and there is no buffer space to store this packet.
    Typically TCP packets are put into order on connections that are inspected by the
    appliance or when packets are sent to SSM for inspection. There is a default queue size
    and when packets in excess of this default queue size are received they will be dropped.
    Recommendations:
    On ASA platforms the queue size could be increased using queue-limit configuration
    under tcp-map.
    Similarly you need to check many reasons for the asp drop logs that you have captured and you need to monitor how much it is increasing and the difference.......
    but 40 % CPU utilization is a okay kind of thing and you do not need to worry if that happens only during peak hours ans it is not increasing drastically more and more.

  • I have high cpu usage due the opendirectoryd activity

    Since I have installed Mavericks, my CPU usage is at a constant level of almost 100%,
    therefore the fans are speeding up en my batteries runs down very fast.
    Before this I had Lion, and everything was running smooth.
    In acitivity moinitor I have seen the following activities: opendirectoryd consuming all of my cpu usage.
    Also, I can't turn WiFi off, it will automatically turn on immediately.
    But even though I closed all my other programs in acitity monitor, this one keeps running and if I force quit it, it opens up again in a second.
    When I take a look at my logs there seems to be a major problem:

    If i don't run any programs, this log seems to appear every few seconds.
    I have a MacBook Pro form late 2011,
    2.4GHz Intel i5 with 4GB RAM and 10.9.1

    I just read briefly about this and correct me if I am wrong. If you are using unix, solaris use the top (% top) command by itself at the command prompt. The output will expose the top users on the system. From there you can drill down to work on the bottleneck causing the high cpu useage. It could be that it is just being very over worked and an upgrade is necessary. Or by using (% netstat -i ) the packets may be too small thereby creating alot of traffic on the system. Reducing the amount of packets by increasing their size without splitting them in the system may reduce the cpu useage.
    Hope this helps.
