Performance Problem : High CPU on a simple Insert

I have a simple INSERT ( INSERT into TABLE values ( :1, :2 ) etc. )
But this statement is exhibiting following characteristics
Optimizer Cost : 1
Buffer Gets : 26 million !!!
Rows : 750,000
Gets/Execution : 35,000
This is causing performance problem on our production.
Any ideas will be appreciated ?
thanks

Performance problem while CPU is 80% Idel ?

Hi,
My end users are claim for performance problem during execution of batch process.
As you can see there are 1,745 statement executing each second.
Awr report shows 98.1% of the time , waits on CPU .
Also Awr report shows that Host CPU is :79.9% Idel.
The second wait event shows only 212 seconds waits on db file sequential read.
Yet , 4 minute in 1 hour period is seems not an issue.
Please advise

if the users are complaining about performance of the batch process, then that's what you should be looking at, not the entire system.I find it strange to see "end users" and "the batch process" in the same sentence (as it was in the first post). "End users" gives me the feeling of a significant number of concurrent sessions with people waiting for results in real time at the far end, while "batch process" carries the image a small number of large scale processes running overnight to prepare the data for the following morning.
I mention this because my first view of the AWR output was: you've got 16 CPUs, only three in use, virtually no users, and doing very little work, how can the users complain. (One answer, of course, is that the 13 CPUs could be locked out of use as far as Oracle is concerned). On the second read I decided that the "users" had gone home, and the complaint was simply that the batch process wasn't completing in time.
In this case I think "the entire system" IS "the batch process"
Determine which stored procedures and/or SQL statements took longer than usual and then find out why. Most likely you'll be able to find
everything you need in AWR views (DBA_HIST_SQL%) and ASH archive (DBA_HIST_ACTIVE_SESS_HISTORY).
If the batch process has changed dramatically and recently, then a simple first step might be to look at the current AWR report, find the few most time-consuming SQL statements, and use the awrsqrpt.sql script to find their history of execution plans.
But I'd also just look at the expensive SQL - bearing in mind, particularly, that there are very few user calls per second, yet many hundred executions per second: it strikes me that there could be quite a lot of PL/SQL going on doing something a little bit expensive many times or some PL/SQL function that calls some SQL that used to be called rarely from an SQL statement but is now (due, perhaps to a change in plan) being called much more frequently - so check SQL Ordered by Executions.

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.

High CPU usage for simple tasks?

Hello,
In iTunes, various tasks take 3-4 seconds to happen/start (rating a song, scrolling up and down within a list of songs, etc.), and I get either rainbow wheel or lag/nothing happening (or both) in the meantime. I did not notice this problem before the new (11) version of iTunes, and no other apps/programs are having issues of any kind. I checked CPU usage while changing the rating of a song and it went to about 55% for 5 seconds or so. That can't be right... it just can't. Is this some kind of bug in iTunes or is there something (simple!) I can do to fix it?
I'm pretty sure I have Genius turned off, but I've never used it so I really don't even know much about it.
iMac 24" w/3.06 GHz processor, 4GB memory, the computer's about 4 or 5 years old but still runs very well everywhere else. Currently running 10.6.8 and my external backup died on me a few months ago, so updating the OS, if there's ANY chance of losing anything, isn't an option right now.
I use iTunes a lot so this is driving me insane. Please help!

"blued" process causing performance problems (98% CPU use)

I have a friend who's MacBook fan is spinning at hi RPM's almost constantly. I took at look at her Activity Monitor and there's a process running called "blued" that seems to be the source of the problem. It runs nearly constantly at 90%+ CPU useage, with frequent spikes into the 96-100% range, which is what I assume is causing the cooling fan to go spinning out of control. Does anyone know what this is? I've Googled it to no avail, and am hesitant to just kill it before I know what it is. Any assistance would be greatly appreciated.

Hi Evan,
I found this in the Apple Developer area: http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/blued.8. html
I would just kill that process from the Activity Monitor.
Also, Run the hardware tests from your Install DVD (hold down d at Boot) and see if it reports any SNS (Temperature Sensor) errors - if one has failed or the leads have become disconnected then the fans will run at maximums revs by default and should go in for service.

Systemuiserver problem - high %cpu

I recently noticed that whenever I start-up m laptop, the "systemuiserver" eats up about 40-50% cpu that causes the laptop to heats-up. I am now in 10.8.3 OSX, mid 2012 MBA and never experienced/noticed this before. I only open a website without heavy graphics nor applications but just a simple browsing. Is this normal or is there anything that can be done to correct this. Note: I can kill the process in activity monitor and it become normal again. But I need to do this every start-up. Thanks in advance.

Seems like this is a persistent issue and the Apple Support community is not responding. I am seeing the activity with only light processes running where in the past, the CPU Usage was only one or two system or user dots in the graph. Now the display looks like a square wave where there are mesas of activity with a fixed time of quiet between them. This is driven by the threads in this process. I wonder what they changed and why? The fan on the laptop runs all the time now.

High cpu usage and game lag problem

i have a hp 15 d103 tx
windows 8.1 64 bit
inel i5 4200m 2.5ghz
anti virus installed avast fee antivirus
im using nvidia 820m geforce 344.75 version driver
ram installed 8gb
im experiencing huge amount lag in games and software (autocad)
whenever i run a game (for eg batman origins) it run smooth till 2 or 3 minutes after it lag horrribly
for sake first im getting 45 frames per second then suddenly frame drop to 13 or even to 10
i have to press alt + tab to check task manger it show cpu usage 30%
after that when again i press alt tab to back to game it runs fine for 20 seconds and again lag
i dont what the problem high cpu uasge
system idle process sometime shows around 82%
with 8gb of ram still expericing lag
this problem is with all game that i have played and software like photoshop and auto cad
my cousin own hp 15 r007tx and having same gpu nvidia 820m game runs for on his laptop without a lag
is it window 8 problem or something else??

wow finally got the solution by updating bios
just updated the bios from 2.7 to 2.8
no lag now
i guess different cpu load gpu switching on off was problem
but now everything is running good

Performance problem - XML and Hashtable

Hello!
I have a strange (or not strange, we don't know) performance problem. The situation is simple: our application runs on Oracle IAS, and gets XML messages from an MQ, and we have to process them.
Sample message:
<RequestDeal RequestId="RequestDeal-20090209200010-998493885" CurrentFragment="0" EndFragment="51" Expires="2009-03-7T08:00:10">
     <Deal>
          <Id>385011</Id>
          <ModifyDate>2009-02-09</ModifyDate>
          <PastDuesOnly>false</PastDuesOnly>
     </Deal>
     <Deal>
          <Id>385015</Id>
          <ModifyDate>2009-02-09</ModifyDate>
          <PastDuesOnly>false</PastDuesOnly>
     </Deal>
</RequestDeal>(there's an average of 50000-80000 deals in the whole message)
After the application receives the whole message, we'd like to parse it, and put the values into a hashtable for further processing:
    Hashtable ht = new Hashtable();
    Node eDeals = getElementNode(docReq, "/RequestDeal");
    Node eDeal = (Element)(eDeals.getFirstChild());
    long start = System.currentTimeMillis();
    while (eDeal != null) {
      String id = getElementText((Element)eDeal, "Id");
      Date modifyDate = getElementDateValue((Element)eDeal, "ModifyDate");
      boolean szukitett = getElementBool((Element)eDeal, "PastDuesOnly", false);
      ht.put(id, new UgyletStatusz(id, modifyDate, szukitett));
      eDeal = eDeal.getNextSibling();
    logger.info("Request adatok betöltve.");
    long end = System.currentTimeMillis();
    logger.info("Hosszu muvelet ideje: " + (end - start) + "ms");The problem is the while statement. On my PC it runs for 15-25 seconds, depends on the number of the deals; but on our customer's server, it runs for 2-5 hours with very high CPU load. The application uses oracle xml parser.
On my PC there are Websphere MQ 5.3 and Oracle 10ias with 1.5 JVM.
On our customers's server there are Websphere MQ 5.3 and Oracle 9ias with 1.4 HotSpot JVM.
Do you have any idea, what can be the cause of the problem?

Do you have any idea, what can be the cause of the problem?All sorts of things are possible.
- MQ is configured differently. For instance transactional versus non-transactional.
- The customer uses a network (multiple computers) and you use a box (singlur) and something is using a lot of bandwidth on the network. Could be your process, one of the dependent processes or something else that has nothing to do with your system
- The processing computer is loaded with something else or something is artificially limiting the processing time of your application (there is a app that allows one to limit another app to one CPU.)
- At least one version of 1.4 had a xml bug that consumed massive amounts of memory when processing large xml. Sound familar? If the physical memory is not up to it then it will be thrashing the hard drive as it swaps virtual in and out.
- Of course virtual memory causing swaps would impact it regardless of the cause.
- The database is loaded.
You can of course at least get the same version of java that they are using. Actually that would seem like a rather good idea to me regardless.

Performance issue with high CPU and IO

Hi guys,
I am encountering huge user response time on a production system and I don’t know how to solve it.
Doing some extra tests and using the instrumentation that we have in the code we concluded that the DB is the bottleneck.
We generated some AWR reports and noticed the CPU was in top wait events. Also noticed that in a random manner some simple sql take a long time to execute. We activated the sql trace on the system and noticed that for very simple SQLs (unique index access on one table) we have huge exec times. 9s
In the trace file the huge time we had it in fetch area: 9.1s cpu and elapsed 9.2.
And no or very small waits for this specific SQL.
it seems like the bottle neck is on the CPU but at that point there were very few processes running on the DB. Why can we have such a big cpu wait on a simple select? This is a machine with 128 cores. We have quicker responses on machines smaller/busier than this.
We noticed that we had a huge db_cache_size (12G) and after we scale it down we noticed some improvements but not enough. How can I prove that there is a link between high CPU and big cache_size? (there was not wait involved in SQL execution). what can we do in the case we need big DB cache size?
The second issue is that I tried to execute an sql on a big table (FTS on a big table. no join). Again on that smaller machine it runs in 30 seconds and on this machine it runs in 1038 seconds.
Also generated a trace for this SQL on the problematic machine:

********************************************************************************The high CPU is present here also but here I have huge wait on db file scattered read.
Looking at the session with the select the AWG_wait for db scattered read was 0.5. on the other machine it is like 0.07.
I though this is an IO issue. I did some IO tests at SO level and it seems like the read and writes operation are very fast…much faster than the machine that has the awg_wait smaller. Why the difference in waits?
One difference between these two DBs is that the problem one has the db block size = 16k and the other one has 8k.
I received some reports done at OS level on CPU and IO usage on the problematic machine (in normal operations). It seems like the CPU is very used and the IO stays very low.
On the other machine, the smaller and the faster one, it is other way around.
What is the problem here? How can I test further? Can I link the high CPU to low/slow IO?
we have 10G on sun os with ASM.
Thanks in advance.

Yes, there are many things you can and should do to isolate this. But first check MOS Poor Performance With Oracle9i and 10g Releases When Using Dynamic Intimate Shared Memory (DISM) [ID 1018855.1] isn't messing you up to start.
Also, be sure and post exact patch levels for both Oracle and OS.
Be sure and check all your I/O settings and see what MOS has to say about those.
Are you using ASSM? See Long running update
Since it got a little better with shrinking the SGA size, that might indicate (wild speculation here, something like) one of the problems is simply too much thrashing within the SGA, as oracle decides "small" objects being full scanned in memory is faster than range scans (or whatever) from disk, overloading the cpu, not allowing the cpu to ask for other full scans from I/O. Possibly made worse by row level locking, or some other app issue that just does too much cpu.
You probably have more than one thing wrong. High fetch count might mean you need to adjust the array size on the clients.
Now that that is all out of the way, if you still haven't found the problem, go through http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
Edit: Oh, see Solaris 10 memory management conflicts with Automatic PGA Memory Management [ID 460424.1] too.

Performance problem inserting lots of rows

I'm a software developer; we have a J2EE-based product that works against Oracle or SQL Server. As part of a benchmarking suite, I insert about 70,000 records into our auditing table (using jdbc, going over the network to a database server). The database server is a smallish desktop Windows machine running Windows Server 2003; it has 384M of RAM, a 1GHz CPU, and plenty of disk.
When using Oracle (9.2.0.3.0), I can insert roughly 2,000 rows per minute. Not too shabby!
HOWEVER -- and this is what's making Oracle look bad -- SQL Server 2000 on the SAME MACHINE is inserting roughly 8,000 rows per minute!
Why is Oracle so slow? The database server is using roughly 50% CPU, so I assume disk speed is an issue. My goal is to get Oracle to compare favorably with SQL Server on the same hardware. Any ideas or suggestions? (I've done a fair amount of Oracle tuning in the past to get SELECTs to run faster, but have never dealt with INSERT performance problems of this magnitude.)
Thanks,

I've tried using a PreparedStatement and a CallableStatement, always with bind variables. (I use a sequence to populate one of the columns, so initially my code was doing the insert, then a select to get the last inserted row. This was fast on SQL Server but slow on Oracle, so I conditionalized my code to use a pl/sql block that does INSERT... RETURNING so I could get the new rowid without doing the extra select - that required switching from PreparedStatement to CallableStatement). The Performance Manager shows "Executes without Parses" > 98%.
Performance Manager also shows Application I/O Physical Reads approx 30/sec, and Background Process I/O Physical Writes approx 60/sec.
File Write Operations showed most of the writes going to my tablespace (which is sized plenty big for the data I'm writing), but with occasional writes to UNTODBS01.DBF as well.
The database is in NOARCHIVELOG mode.
I'm NOT committing very often - I'm doing all 70,000 rows as one transaction. BTW, I realize this isn't a real-life scenario - this is just the setup I do so that I can run some benchmarks on various queries that our application performs. Once I get into those, I'm sure I'll have a whole new slew of questions for the group. ;-)
I'll look into SQL TRACE and TKPROF - time to refresh some skills I haven't used in a while...

Performance Regression: After update to FireFox 18 permanent high CPU load

After the last update FireFox started to continuously eat a whole CPU on my 2-core laptop. My usage pattern (regarding browsed sites and/or activated plugins) has not changed, but I must confess that I'm a heavy user of plugins.
I suspect the problem may arise from a changed performance behaviour of a plugin due to the new JS engine of FF18, but how can I easily trace this problem further down. I.e. is there a way to inspect the collected performance data of firefox (activated)?

I use FF always with many tabs opened, min 100, sometimes up to 300+. After Updating FF17 to FF18 I've recognized a much more higher CPU-usage.
This issue doesn't occur as long as there are just a few tabs opened, or it doesnt' be of any consequence at least. The CPU-load of FF18 gets higher with each opened tab. When you close the tabs, the CPU-usage also gets normal. There is nearly no Flash-content and just few JS working on the websites (thanks to NoScript and ABP).
The System: i5-CPU, 16GB RAM, Win7 x64
FF17.01: CPU-load 1.0% average at 300 tabs
FF18.01: CPU-load 10.0% average at 300 tabs FF18.01: CPU-load 5.0% average at 150 tabs FF18.01: CPU-load 3.3% average at 100 tabs
A fresh install and disabling all addons (even in Safemode) didn't fix the problem. It seems, that FF is permanetly doing something with the tabs to being able to speedup on user-action. It's all good, as long as there are just a few tabs opened, but it's getting worse with each further opened tab.
I've opened a bug-ticket at https://bugzilla.mozilla.org/show_bug.cgi?id=832864

MSI KT6 Delta LSR SATA to PATA High CPU Usage Problem

Well recently I've switch to my one of my other motherboards on my network to a MSI KT6 Delta LSR, it was working fine after a reformat, but I notice a few problems and that is 100% cpu usage for SATA to PATA, and vice versa, which seems really crazy. Then my network card performance is ISDN speed sluggish, and I tested my line to be working 100% with another mobo. But when I put another NIC on the same mobo it suffers the same speed problems.
Any suggestions? The rig is specs:
Barton 2500+
Antec QuietPower 350W
200GB Seagate SATA HDD
40GB Seagate PATA HDD
ATI Radeon 7500 AIW
Audigy 2 Value
Realtek 8139 NIC
MSI KT6 Delta LSR Mobo
2x512 MB PC 2700 RAM
Pioneer 107D DVD Writer
LG 16X DVD-ROM
56K Modem (A-open)

Shouldn't say what I don't know about SATA, but since I found below, I need ask if VIA 4in1 drivers are installed, preferably while in SafeMode I say:

I recently installed 160g Seagate barracuda 7200.7 drive on SATA port. (I enabled the Bios using Auto) I have a P4I865pea-6al mother board, with two PATA drives . When copying files between the PATA drives on ide ports, to or from, the SATA drive, I notice the CPU usage goes up to 100%, but when copying files from one ide drive (the PATA drives) to another the CPU usage is very low.
Is there a bios setting that will allow me to copy files from the SATA drive to the Pata drives using a small amount of CPU power, found when just copying between the Primary and Secondary IDE drives? I am using Adobe premiere pro, which uses a lot of CPU power, and the high CPU usage of the SATA drive crashes this program? Any help would be appreciated

have you installed the newest chipset- and ide drivers ?

Kernel task over 100%. High CPU Load. High Temp. Problem Solved.

Hi,
I thought i would make a post as i had been having trouble with my 13 inch mid 2009 MBP for sometime (6 months), with runaway kernel tasks causing high CPU loads. I had searched through forums and discussions for a long time trying to find the problem and isolate it. Initially i discovered some problems with finder preferances that were chewing up CPU which i solved by deleting the prefereance file, allowing the system to recreate a non corrupted version. This helped but still i had problems. I tried maintainance suites like onyx, reseting PRAM, booting into safe mode, hardware checks and diagnostics, and more little tricks than i can remember. Nothing i tried really seemed to make a differance. Through reading on this forum and others i found out the kernel tasks can be a direct result of hi CPU core temps as the system runs a lot of small kernel tasks to try and take some of the CPU load away from processor intensive processes that may be contributing to hi CPU load. The thing which solved my problem in the end was opening up my MBP, being careful not to touch the logic board and literally puting my vacuum cleaner over the fan, sucking dust and dirt and dust out of my latop. This computer has been through the dirt with me, literally its been dragged through rural south east asia for a year and accompianied me to warhouse parties to perform and run lighting and visuals. Its little wonder the fan was obviously clogged. I know people tend to be holier than though with their mac products and treat them with the upmost respect, but my love for the MBP has come from how sturdy and reliable it has been under less than desirable conditions.
Now im not telling people this is what they should do, i had just noticed alot of people with this problem in my attempts to solve mine, and in the end this is what helped. My MBP now runs at a temperature where i can touch the metal near the CPU without being worried about a 3rd degree burn and the CPU load is acceptable with no run away kernel tasks. Like i saw this might not be the cause of your porblem, as my laptop has lived a rough and fun life so far, but i thought i would share this with you all as i have had contstant help from this forum and others searches for solutions to problems with my apple products.

Already tried SMC and PRAM-reset with no luck.
On my MacBook late 2008 it's the same effect.

FMS 4 configuration / High CPU usage problem

I am seeing extremly high CPU usage issues with the FMS 4 server. It seems to be a problem with the FMS Edge process? If you start and stop the service, the processor goes back to normal operations.
Looking in the Windows Event logs I am seeing these errors:
Bad network data; terminating connection : bad chunk version 104 on input stream 00000000077A2E80
Also:
Bad network data; terminating connection : (Adaptor: _defaultRoot_, VHost: Unknown, IP: , App: , Protocol: tunnel) : h o s t = % 2 2 % 2 0 % 2 D F O O B A R % 7 C e c h o % 2 0 % 2 2 % 2 0 S h a r e n a m e % 2 2 % 0 A e c h o % 0 A e c h o % 2 0 % 2 2 % 2 0 % 2 0 S o m e S h a r e % 2 0 % 2 0 D i s k % 2 0 % 2 2 % 6 0 i d % 6 0 % 2 0 % 2 3 % 2 2
Can someone shed some light on what might be causing these issues?

Hi
Can you please provide us some little more environment information on this issue, like:
- what were you trying to do when you saw this issue, if there was a live telecast or if that was a simple vod workflow?
- What publisher application were you using to send livestream to FMS?
- were you also doing some kind of recording while doing live streaming??
- In case of live streaming what audio/video encoding and bitrates was there in use?
- how many number of connections were there?
- What amount of cpu and mem usage was there (when you say very high cpu usage).. you can see it using task manager
It will help if you can also share your fms logs (inside fms_install_folder/logs) so that we can see if something abnormal was going on there..
