MacPro 2008 Logic CPU Usage (EvanLogicBenchmark Test)
Some days ago I did the EvanLogicBenchmark Test on my MacPro Quad 2x2.8 gHz just for fun, but the results were somehow not quite funny:
Logic 64 Bit: 58 Tracks
Logic 32 Bit: only 16 Tracks
As I use logic 32Bit that performance counts for me. I know that normally the 32 Bit mode should show just about the same performance as the 64 Bit mode, but I also saw some reports from people having the same decrease on a MacPro 2008 in 32 Bit mode.
Looking at the activity monitor I can see a CPU usage of 35% (in total) with the 16 tracks playing in 32Bit mode.
Maybe someone can confirm this or has found the reason for that lack of performance?
12 GB RAM / 4x SATA HDs
OS X 10.6.3 / Logic 9.1.1
256 buffer / Fireface 800
2xATI Radeon HD 2600 XT
MOTU PCI 424
That cannot be right. When you go to 32 bit, performance is cut to just over a QUARTER of 64-bit performance?? I believe that the 'normal' difference should be around 10 %, so I'ld expect if you get 58 tracks at 64 bit, you should be able to get around 50+ tracks on 32 bit. At how many bits do you run SL?

MacPro and Excessive CPU usage
Still trying to figure out what is happening to my 2.66 MP.
At least once a day, for no apparent reason, the first core will all of a sudden go to 100% usage and despite what I close, it stays there. I close every app and even log out and log back in and it doesn't change. If I restart, the problem is gone.
I did run Migration Assistant from my old QS G4.
I am running 10.4.8 with 3 Ghz of RAM. I ran AHT and the system and RAM checks out fine. Even ran the new Universal Applejack. Problem still remains. It is so intermittent it is going to be impossible to troubleshoot. When it started today, I was noticed it after I started iTunes in that the audio would break-up. Any clues?Happening Now this is from terminal

Terminal Server 2008 R2 - Adobe 9.0 CPU Usage
We are currently running 5 Windows 2008 R2 64bit, RDS severs with 200 users. We are having a major problem with adobe reader and running on these servers Every instance of adobe reader is taking 11-14% of the CPU. So once 5-6 people get on the CPU is maxed and starts slowing things down.
Hardware
DL360 G6
2 75 GB drives Mirrored
16.0 GB Ram
Intel(R) Xeon(R) CPU E5506 @2.13GHZ (@ processors)
The updater is disabled and is no running.
We had adobe Professional 6 installed but that was removed off one of the servers in hope that was causing the issue. No luck the one server only has adobe reader and is still having issues.
Any help would be greatly appreciated.Just adding here in the hope it might help someone in the future. The high CPU usage occurs because you are using redirected Application Data folders in your Terminal Services/RDS/Citrix environment. As of v9.x (and maybe 8.6) Adobe state (hidden in the release notes) that redirected AppData folders are no longer supported. I've tested versions from 9.0 to 9.3.3 so far and they all exhibit this behaviour.
From my reading around the web it looks like people have suggested that when Reader starts it checks it has write access to not only the AppData\Adobe folder, but also to the root of the AppData path. In most cases this is a server name as part of a UNC path and the check will fail. I have also tested redirecting by GPO to a mapped drive (the users homedrive on H:\) but the path gets expanded to the full UNC path when being parsed by the app so the same CPU consumption seems to happen.
Only fixes I've seen work are downgrading to a prior version (prior to 8.6 according to some on the web), or stopping the AppData folder redirection and setting it back to be part of the profile path. When stopping AppData redirection I have also set the AppData folder to be excluded from the roaming profile via GPO, and use a Profile Management tool (e.g. Flex or Citrix Profile Management) to copy only the relevant parts of AppData to the network in an effort to prevent negatively impacting logon times too much.
Hope this helps.

Ableton Live 6 vs Logic Pro 8 CPU usage/audio quality.
Hi,
Any user's have feedback regarding CPU usage between Abelton Live 6 vs Logic Pro 8. I'm currently running Live 6 on an MBP 2.0ghz (CD) and am constantly running into audio drop outs etc etc.I am reading throughout the net that Logic Pro 8 is more CPU friendly than LIve 6... is this true, overall? Also any users ever do a mixing test between the two apps to see if there was an audio difference when rendering your final project to aiff or wav? I am thinking on using Live 6 as a stratch pad to "create" as I enjoy it's flexibility then transfer the project over to Logic, however that depends if there really is a difference in CPU usage and Audio quality between the two DAW's.
Thanks.
guess i should also state that i will be running on the new imac's come tax return time. lolLogic 8 is very CPU friendly, I can say that much. I never found Ableton Live 5 to be very taxing either, though. Pro Tools is.
But like you I use Ableton as a scratchpad, I love how it works, and Logic for the finishing touches. But that's just because I'm not good at Logic yet. Not fast at it.
Get them both! You'll be glad you did. -
24" iMac summer 2008. CPU fan runs at highest speed, some times goes to "sleep" mode. CPU t' is about 35'- 42'C. Run hardware test: 4sns/1/40000000:tlop-130.000, next time 4sns/1/40000000:tlop-128.000 errors. Tried SMC, NVRAM, PRAM. Reinstalled all softwere. Nothing changed.
I suspect you have hardware problem with a fan sensor. Doing a software install will not help the machine needs to be taken in for service. If you run Apple Hardware Test in Extended Mode it should reveal the error code. If it does not then run AHT an additional 2-3 times to be sure in Extended Mode. Each pass will take about 30-60 minutes.

Evenlog viewing causes CPU usage 100% on Windows server 2008 SP2
We have Windows server 2008 SP2 with strange behaviour. When I scroll down events in eventlog viewer CPU usage hits 100% and eventlog viewer freeze. CPU usage is split between 2 processes SVCHOST.EXE (lmhosts, eventlog and Dhcp services) and MMC.EXE.
1)I tried to replace eventlog files with new ones. That didn’t helped
2)After server clean boot problem still exist.
3)When CPU hits 100% usage process explorer shows that from SVCHOST.EXE process CPU is used by service EventLog.
Any ideas how to fix this?Hi Santosh
I re-installed VMware
tools and also configured VMXNET 3 - nothing changed :(
Sorry to hear that.
Windows event log service has couple of dependencies i.e. task scheduler and windows event collector service. Can try restrating those services ?
In addition to above, try following steps
Change NTFS permission of %WINDIR%\System32\WinEvt\Logs directory, add Local Service and
Network Service, give them FULL permissions.
Stop and Start event viewer service by running following command
net stop eventlog && net start eventlog
Issues like this might occur if the disk (FC or iSCSI SAN or even NAS) has some inconsistencies , this is true in case of both physical and virtual machines
You might want to try running chkdisk as well on the server in question

If nothing helps, try inplace upgrade of the Operating system as an last option.

I could definitely use some help!
I am a well experience Logic Pro 9 user, and I am having some serious issues with CPU usage. I have a Mac Mini Server with a 2 GHz Core i7 and 8 GB of 1333 MHz DDR3 RAM. With my current system, I run all of my applications and operating system on a dedicated internal HD. All my sessions are run from a seperate internal HD.
Typically I don't experience many issues with CPU usage with exception of this project. Every 5 seconds I get this error.
"System Overload.
The audio engine was not able to process all required data in time.
(-10011)"
I have tried everything under the sun and even the old "who's your father" trick to eliminate this issue. NOTHING has worked yet. Here's what I've done so far:
1. Increase my buffer size to it's max at 1024 samples.
2. Freeze all tracks which I use heavy processing plugins.
3. Flatten and merge all take folders.
4. Merge all audio regions.
5. Delete all unused audio regions in my bin.
6. Set all channels to "No Input"
7. Close out of all other programs.
8. Turn off WiFi.
9. Turn off Bluetooth
I'm currently running 35 audio tracks, 3 Aux tracks and 0 midi tracks. I have very little automation, and I'm not using Flex time. I have never experience this much CPU usage ever, and it's driving me INSANE.
Any help is grealy appreciated.What does the Drive/CPU usage (Performance) metering look like in Logic? That overload error can mean a lot of different things. Typically... it's a system bus overload and can be caused by Logic's Space Designer and/or Delay Designer. What is the Process Buffer Range set at?
Have you tried a project of this size since upgrading to 10.8.4?
Curious, what sample rate are you using?
I like AOL's idea of importing each track, might narrow it down. -
How to reduce CPU usage when working in Logic Pro and Kontakt5
Hello All,
I have a MacBook Pro 15" early 2011 2.0 GHZ. My main acitivity is making music with my macbook pro. I am using Logic Pro 9 in combination with Kontakt 5.
I want to get some suggestions in the setup so I can reduce the usage of the CPU. By the way I have upgraded my system with a SSD 256GB , 16GB RAM and have removed the optical drive and installed the the previous factory set HD in the optical bay. I have placed the samples of the Kontakt 5 in the HD so I have enough space on my SSD to run the progrmas fast and smooth !
If possible give your advise on an optimum setup such as reachanaling the sounds through BUS to AUX channels and other methods in order to reduce the CPU usage. You may even post some good links where I can find more info.
Thanks in advance

So Center of Pan,
If you were to run something like Omnipshere on an active SI track do you get anywhere near the "1 core CPU" spike I'm getting on my Late 2011 TOTR MBP?
I still dont really get why L9 on a new MBP peforms worse than eg your PC.
Older versions of Logic (ie: 5.5) don't see individual cores, there is one disk meter and one CPU meter. In some ways it's a more efficient system. This is running on WinXP which happens to be a very good system for audio. Consider this, XP can be installed and take up only half a gig of disk space and do 90% of what most operating systems can do today.
I do see single core spikes on my single processor quad core Mac Pro. There's no way to get around a processor intensive plugin on a single track. A channel strip is tied to a single process (core). I stopped upgrading at 10.6.8 and Logic 9.1.3, because it works. I still get the occasional single core use even with multiple plugs and tracks but I can usually break the logjam by quickly starting and stopping Logic 2 or 3 times.
I will not upgrade Mac hardware or software unless the next version of Logic is outstanding, I'm fine where I'm at for the next year or two. I enjoy recording performers more than anything else so al I really need is a good sounding, solid system. -

The SQL statement is forcing the use of a specific index, is this the best index?:
SELECT /*+ INDEX (OM_COURSE_FEE OCF_CFC_CODE) */DISTINCT CF_COURSE_CODE FROM OM_COURSE_FEE,OT_STUDENT_FEE_COL_HEAD,OT_STUDENT_FEE_COL_DETL WHERE SFCH_SYS_ID = SFCD_SFCH_SYS_ID AND
SFCD_FEE_TYPE_CODE = CF_TYPE_CODE AND CF_COURSE_CODE IN ( 'PE1','PE2','CCT','CPT' ) AND SFCH_TXN_CODE = :b1 AND SFCD_SUBSCRBE_JOURNAL_YN IN ( 'T','R','1','C' ) AND SFCH_APPR_UID IS NOT NULL
AND SFCH_APPR_DT IS NOT NULL AND SFCH_NO = :b2 AND NOT EXISTS (SELECT 'X' FROM OM_STUDENT_HEAD WHERE STUD_SRN = SFCH_STUD_SRN_TEMP_NO AND NVL(STUD_CLO_STATUS,0) != 1 AND
NVL(STUD_REG_STATUS,0) != 23 AND STUD_COURSE_CODE != 'CCT' AND CF_COURSE_CODE= STUD_COURSE_CODE ) ORDER BY 1 DESC
Unfortunately, explain plans, even with dbms_xplan.display, may not show the actual execution plan - this is more of a problem when the SQL statement includes bind variables (capturing a 10046 trace at level 8 or 12 will help). With the information provided, it looks like the problem is with the number of logical reads performed: 17,503,305 in 84 executions = 208,373 logical reads per execution. Something is causing the SQL statement to execute inefficiently, possibly a join problem between tables, possibly the forced use of an index.
From one of my previous posts related to this same SQL statement:
SELECT /*+ INDEX (OM_COURSE_FEE OCF_CFC_CODE) */ DISTINCT
CF_COURSE_CODE
FROM
OM_COURSE_FEE,
OT_STUDENT_FEE_COL_HEAD,
OT_STUDENT_FEE_COL_DETL
WHERE
SFCH_SYS_ID = SFCD_SFCH_SYS_ID
AND SFCD_FEE_TYPE_CODE = CF_TYPE_CODE
AND CF_COURSE_CODE IN ( 'PE1','PE2','CCT','CPT' )
AND SFCH_TXN_CODE = :b1
AND SFCD_SUBSCRBE_JOURNAL_YN IN ( 'T','R','1','C' )
AND SFCH_APPR_UID IS NOT NULL
AND SFCH_APPR_DT IS NOT NULL
AND SFCH_NO = :b2
AND NOT EXISTS (
SELECT
'X'
FROM
OM_STUDENT_HEAD
WHERE
STUD_SRN = SFCH_STUD_SRN_TEMP_NO
AND NVL(STUD_CLO_STATUS,0) != 1
AND NVL(STUD_REG_STATUS,0) != 23
AND STUD_COURSE_CODE != 'CCT'
AND CF_COURSE_CODE = STUD_COURSE_CODE)

There is the possibility of additional predicates being generated by Oracle which will make this possible without introducing a Cartesian join, but those predicates are not displayed with an explain plan (they will appear with a DBMS_XPLAN). I may not be remembering correctly, but if the optimizer goal is set to first rows, a Cartesian join might appear in a plan as a nested loops join - Jonathan will know for certain if that is the case.
Have you investigated the above as a possible cause? If you know that there is a problem with this one SQL statement, a 10046 trace at level 8 or 12 is much more helpful than a Statspack report.

downgrading gnome-session to 2.24.1 (keeping xorg 1.5.3) seems to correct the high CPU usage problem. This tip comes from the gnome thread. It appears to break gnome screensaver, but I can live with that. Hardware: MSI VR340 laptop with Intel GM965 video.
Hope it helps.
Yes this solution works! Thx for the hint! For everybody who forgot how to downgrade packages here the solution:
I downgraded like this: sudo pacman -U gnome-session-2.24.3-1-i686.pkg.tar.gz
Maybe you have another gnome-session in your pacman cache. More information about downgrading packages:

Still hope that xorg 1.6 will come soon to the official repository -
Kernel Task over 400% CPU usage
Hello, I have some questions about the Kernel Task in my activity monitor.
Recently, after a hard disk failure, I have my Macbook Pro wiped and start afresh with Mavericks. All was well, but it slowed down tremendously in the last couple of days. I checked the activity monitor and Kernel Task is always around 400-470%, sometimes it even peaked to 1000+%! I closed all my applications but it is still taking up all my RAM. I cannot work when it is freezing up every 2 seconds. What is the problem?
Here is the report, if it helps:

Throttling
When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, 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 battery power, the fault is in the battery or the logic board. If it happens only on AC power, charging is causing the machine to heat up. That may be normal on 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. -
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);

AND (primid = primid OR UPPER (username) = uname OR uiname = uname
AND (deldate IS NULL)

INSERT INTO TEST

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

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.

Why animation keeps breaking even though CPU usage oscilate between 60-90%?
I made a simple animation.
In standalone player there is no breaking, but in browser every few seconds it stops and jumps, even though through all the time CPU usage never exceeds 100% but oscillate between 60 and 90%.
I tested it on two machines, both dual core above 4 GHz and result is the same.
Any ideas why and what to to to fix it?

S.J.this is an excerpt from one chapter (optimizing game performance) of a book i wrote (Flash Game Development: In a Social, Mobile and 3D World), and is intended to show this is not necessarily a simple topic amenable to a forum-fix.
Optimization Techniques
Unfortunately, I know of no completely satisfactory way to organize this information. In what follows, I discuss memory management first with sub-topics listed in alphabetical order. Then I discuss CPU/GPU management with sub-topics listed in alphabetical order.
That may seem logical but there are, at least, two problems with that organization.
I do not believe it is the most helpful way to organize this information.
Memory management affects CPU/GPU usage, so everything in the Memory Management section could also be listed in the CPU/GPU section.
Anyway, I am going to also list the information two other ways, from easiest to hardest to implement and from greatest to least benefit.
Both of those later listings are subjective and are dependent on developer experience and capabilities, as well as, the test situation and test environment. I very much doubt there would be a consensus on ordering of these lists. Nevertheless, I think they still are worthwhile.
Easiest to Hardest to Implement
Do not use Filters.
Always use reverse for-loops and avoid do-loops and avoid while-loops.
Explicitly stop Timers to ready them for gc (garbage collection).
Use weak event listeners and remove listeners.
Strictly type variables whenever possible.
Explicitly disable mouse interactivity when mouse interactivity not needed.
Replace dispatchEvents with callback functions whenever possible.
Stop Sounds to enable Sounds and SoundChannels to be gc'd.
Use the most basic DisplayObject needed.
Always use cacheAsBitmap and cacheAsBitmapMatrix with air apps (i.e., mobile devices).
Reuse Objects whenever possible.
Event.ENTER_FRAME loops: Use different listeners and different listener functions applied to as few DisplayObjects as possible.
Pool Objects instead of creating and gc'ing Objects.
Use partial blitting.
Use stage blitting.
Use Stage3D.
Greatest to Least Benefit
Use stage blitting (if there is enough system memory).
Use Stage3D.
Use partial blitting.
Use cacheAsBitmap and cacheAsBitmapMatrix with mobile devices.
Explicitly disable mouse interactivity when mouse interactivity not needed.
Do not use Filters.
Use the most basic DisplayObject needed.
Reuse Objects whenever possible.
Event.ENTER_FRAME loops: Use different listeners and different listener functions applied to as few DisplayObjects as possible.

Hemant Joshi.What information is in the referenced trace file. You should probably open a SR with Oracle support and upload the alter log entry for the time of the problem and the referenced trace file.
You should probably search the metalink web site but here is one known issue on 10.2.0.3
Problem: High CPU on box / server
excessive CPU to be used for the checksum routine.
Affects: 10.2.0.3
Bug: 6814520
Fix: 10.2.0.5, 11.1.0.7, patch being develop for 10.2.0.4
Workaround: alter system set db_block_checksum=FALSE
Because of the 07445 errors I would search for other causes of your problem but i thought I would post the error information since it is for your version and involves excessive cpu consumption.
