Serious performance problems after updating from 10.5.6 to 10.5.7

I've got a Macbook Pro C2D 15" (late 2006). After updating the system from 10.5.6 to 10.5.7 and quicktime to 7.6.2, I experience serious performance problems which I have never seen before:
-From time to time, kernel_task has peaks in activity monitor (consumes a lot of CPU). In that moment, the mouse hangs for a short moment and audio playback is distorted/has drop outs.
-Recording audio consumes a lot of CPU (independent of the audio application).
-Video playback consumes a lot of CPU, regardless if I use VLC or the quicktime player.
Any idea what could be done? Thanks in advance.

After a few days of using CoolBook I report that my 1st generation MacBook Air is now reliable and never overheating, regardless of environment conditions.
I must point out that I do believe that it really is something new in 10.5.7 that is causing this problem as my environmental conditions have not changed and even Summer in Dublin still sees temperatures no more than 72F/22C. I am now in Madrid, where the environment is quite different, and I am still having no problem with kernel_task spinning.
I plan on reporting my problem to Apple anyway and being aggressive about the issue as MacLovinRanga did in this thread (http://discussions.apple.com/thread.jspa?messageID=9647353#9647353). Perhaps many/all of those of us having this problem will obtain new MacBook Airs.

Performance problems after Update from 7.6.00.37 to 7.6.03.15

Hi,
after the Update from 7.6.00.37 to 7.6.03.15 in our live system we noticed a lot of performance problems. We have tested the new version before on our test system, but there don't noticed effects like this.
We have 2 identical systems (Opteron 64 bit, openSuse 10.2) with log shipping between them. We updated first the standby system, switched from online to standby (with copy of cold log) and started the new server as online system. After that we run a complete backup (runtime: 1 hour) for starting a new backup history and for activating autolog. Then
With the update we changed USE_OPEN_DIRECT to YES, but the performance of the system was very slow afterwards. After the backup it remains at a high load average (> 10, previous system had about 2-4), with nearly 100% of CPU usage for the db kernel process.
Next day we switched USE_OPEN_DIRECT back to NO. The system first runs better, but periodically rises up to a load average of 6 and slow down the performance of various applications (somebody says about 10 times slower). Here we also noticed a high usage (now 200-300%) of the db kernel process.
Our questions are:
1. Has something basically changed from 7.6.00.37 to 7.6.03.15, so that our various applications (JDBC, ODBC and Perl/SQLDBC partially on old linux systems with drivers from 7.5.00.23) don't reach same performance as before?
2. Are there any other (new) parameters, which can help? Maybe reducing MAXCPU from 4 to 3 for reserving capacities for the system (there is only one maxdb instance running)?
3. Is the a possibility to switch back to 7.6.00.37 (only for worst case)?
I have made some first steps with x_cons, but don't see any anomalies on the first look.
Regards,
Thomas

Hmm... that is really odd. When using USE_OPEN_DIRECT there is actually less work to do for he operating system.

Well of course there are bugs that have been found inbetween the release of both versions, but I am not aware of something like the performance killer.
We will have to check this in detail here.

Well - then I guess 'looking at the system' won't bring you far...

Great - let's see the warnings you get.
Let us also see the DB Parameters you set.

With the old version we had no problems with missing indexes or the general performance. Unfortunatly it is very difficult to extract some sql statements out of the JBoss applications. But even simple queries (without any join) runs slower, when the load average rises over 4-5.
Hmm... the question here is still, if the execution plans are good enough to meet your expectations.
E.g. for tables that you access via the primary key it actually doesn't matter how many rows a table has (not for MaxDB at least).

Sounds like the I/O is your most suspect aspect for overall system performance...

Ok - so this is next to no testing at all when it comes to performance.
> An UPDATE STATISTICS over all db users seems to change nothing. At the moment the system remains markedly slow and we are searching for reasons and solutions. Another attempt will be the change of MAXCPU from 4 to 3.
Why do you want to do that? Have you observed any threads that don't get a CPU because all 4 cores are used by the MaxDB kernel?

Problems after updating from Mavericks to Yosemite.

Hello everyone.I have noticed some battery problems after updating from Mavericks to Yosemite like no charging at all (but the orange led was on )and not able to fully charged.I solve them with SMC reset and PRAM reset.Furthermore, battery discharges faster than before and its really annoying.Now I have notice that the upper right corner of my mac is getting hot.I'll appreciate any help
MacBook Pro (Retina, 13-inch, Late 2013

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
How to Clean Install OS X Yosemite
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Thinkpad G40 keyboard problems after updating from W98 to W7

Hi community users.
I'm new here with a, for me, typical problem.
I’m having a problem with my Laptop keyboard IBM ThinkPad G40, type: 23884SG, Windows 7.
Since I updated from Windows 98 to Windows 7 the keyboard definition is wrong. I’m not able to find the right configuration of it on base of the standard list of country and language definitions in W7.
Who can help me with this.
I already installed some drivers from the Lenova site but nothing seems to help.
So the problem is that I can’t find the right service from the country and language menu to the keyboard in W7.
All suggestions are very welcome.
Thanks in advance,
Dirk
Moderator Note; s/n & UUID edited for members own protection

Hi Vince,
Thanks for your response to my problem.
Problem isn't the choice of the specific language. The problem after the update is that I'm not able to choose the right combination of language and the type of keyboard selection in Windows 7. The selection list is long: from South-Africa to Sweden.
Although most of the characters on the keys on the lower part of the keyboard correspond with the ones on the screen but especially the keys on the upper part don't.
So I'm searching to a correct selection of the combination language and specific type of keyboard. Or there must be some driver witch can be download.
Looking forward to the feedback.
Kind regards,
Dirk

Performance problem after upgrade from Web version to Basic version

A couple days I ago I 'upgraded' my SQL Azure database from the Web service tier to Basic. Since doing that the performance on many of my queries as dropped noticeably. I've made no schema changes, and the amount of data in my database has changed very
little since the upgrade. Has anyone had this same problem?
Randy Minder

Randy,
See this blog about how to upgrade to the new tiers and some advice on finding the right fit.
http://azure.microsoft.com/en-us/documentation/articles/sql-database-upgrade-new-service-tiers/
Basic is not equivalent to Web in the new Editions tiers. While you do 'upgrade' to editions, granting you access to new features and the tiers themselves, you can now choose an experience which has less performance than you had previous in Web/Business.
Try upgrading your server to a new tier based on the advice in the article above. If you read the article below:
https://msdn.microsoft.com/en-us/library/azure/dn369873.aspx
You can see that standard is actually targeting at many of the production use cases of Web, where Basic is targeting developers who were using Web, before, to test out their applications. Basic isn't intended for scenarios with multiple concurrent users.
Hopefully that helped. If you have any other questions, feel free to reply.
Regards,
Chris

IPhone 5s Performance Problem after updating to 7.1.1

Hi everyone,
I was using ios 7 which come originally when you but iPhone 5s , it was great , fast and adorable .
yesterday I updated my iPhone 5s to ios 7.1.1
unfortunately I have faced some problems , the iphone 5s is now slower , the apps open slower than the ios 7,
I have iphone 5 which has ios 7.0.4 and it's much faster and smoother than the iphone 5s which has ios 7.1.1 ,
I was really disappointed about that ,
what do you think the problem is ?
Regards

thanks for your help fred and aszter
my wife's iphone 5s is having the same problem as mine.
I also compared them to my daughters ipad mini that runs 7.0.4 (A5 chip). and that thing runs properly.
FASTER than both our iphone 5s!!!!
wait it gets worse.
I dug up my old 4s installed 7.1.1 . Guess what?
it opens apps with the same speed as my 5s (as slow)
it seems that apple has on purpose implemented an artificial lag on all devices so that the new iphone will appear snappier than the older ones.
not sure about you guys but this is definitely not making me want to go out and stand in line for their new kit and to think that I was actually looking forward to buy an iphone with a bigger screen. not so much any more..
As you can tell I own a lot of apple products. maybe I will come around - it's not like samsung is god's gift to humanity. But This is definitely making question apple. Maybe HTC deserves a chance by me.
I also have a developer id so I am downloading the correct 7.1 ipsw as well and I will try again right now to put it on. first attempt didn't work out, I just upgraded itunes as well to see if that helps, I am putting it on recovery mode.
Just for the record, closing wifi, seems to randomly improve performance in some cases but not all the times..
biggest problem is in photos.

Problems after updating from 2.0.5 to 2.08

Hi Community,
I updated my Developer Studio from 2.05 to 2.08 but I got some problems now. The Behaviour of my WD Application written on 2.0.5 changed.
I got a View which contains a tree control. For this tree control I implemented the method onActionSelect.
public void onActionSelect(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, com.sap.tut.wd.tree.wdp.IPrivateTreeView.ITreeNodeElement selectedElement )
//@@begin onActionSelect(ServerEvent)
if( selectedElement == null)
wdContext.currentContextElement().setLabelname("Element = null");
//wdThis.wdFirePlugToDispatcherView(selectedElement);
//@@end
If I check the parameter selectedElement now for null, I get true. That means this structure isn't filled out automatically anymore.
Do s.b. know something about API changes or how to fix this problem? Regards and thank's a lot, Robert.

Hi Robert,
Errors occur if there are inconsistencies between the Engine (e.g. Support Package 5) and the Developer Studio (e.g. Support Package 6).
Other "Class not found exceptions" or "No such method exceptions" may appear in the case of other Support Packages. Unfortunately, this results in a termination of the application at runtime.
You must ensure that the local version of the Netweaver Developer Studio has the same version level as the CBS
configuration.
In particular, the IDE plug-ins must not have a higher version than the generators of the CBS. Possible is a lower version of the IDE.
Hope that helps.
Best regards,
Karin

Explain plan looks different in steps 19 to 28. I am not sure why 10g have more steps

Hi
I have no experience in 8i. I do know 10g does costing different from 8i. So I think the other plan might got elliminated.
Normally when I see differences. I just collect statistics on the tables and the indexes and remove the hints. Hints are not good . This has helped me to solve few problems.
Thanks

Mobile App problem after update from Flex SDK 4.5 to 4.5.1

I have a mobile app that built in SDK 4.5 and running ok until update the SDK to 4.5.1 and then the app only loads the splash page and not even to to the firstview. The screen just stop at the splash page and no reaction, no debug window popup (test on the computer). If I change back to SDK 4.5, everything goes normal. Does anyone has the same issue? Please help.
I am in Win 7, Flash Builder SDK 4.5.1 plugin in Eclipse Helios.
Thanks.
Tony

Thanks for your respond. I wish I could show you my app; however this project is pretty big. Besides the UI part that was built for mobile, there are also part of the codes are including (referenceing) the old desktop project that still are complie in SDK 4.1. Mainly for the referencing codes to the old project are Caingorm's commands and service locators part, for getting the service call. Everything is fine and running on computer and mobile devices when using SDK 4.5.
I can try to build something to see if it will show the same situation. Thanks.

Fire fox 14 is crashing every 15 minutes. Usining win7 .This is after updating from FF13. require a solution.

FF14 is crashing randomly after every 15 minutes. Is this problem a general problem after updating from FF13. All plugins are up to date. No virus on system. Does any one have any solutions?
Thanks

More information, from the crash report for the first Crash ID listed in "More system details":
https://crash-stats.mozilla.com/report/index/63e76a0f-b807-4eab-a83c-4d14c2120719 Firefox 14.0.1 Crash Report [@ StrChrIA ]
.....the crash report links to a related bug,
[https://bugzilla.mozilla.org/show_bug.cgi?id=530074
Bug 530074 - Crash [@ StrChrIA ] from winsock and shlwapi.dll (LSP, evil *x86.dll module, or BitDefender)]
So, your crash seems to be related to Bit Defender antivirus software or one if its components (BdProvider.dll). I did a google search and according to [http://systemexplorer.net/filereviews.php?fid=11324853 this page], the file BdProvider.dll is the Bitdefender parental provider plugin.
If Firefox no longer crashes when you [[Safe Mode|restart with add-ons disabled]], look in the Firefox Add-ons Extensions list for any BitDefender add-on and disable it (see [[Disable or remove add-ons]] for details), then restart Firefox to see if the crashes stop.
You could also contact BitDefender support or ask for help on the [http://forum.bitdefender.com BitDefender forums].

Serious performance problems

Hi
I am having some very serious performance problems witgh java web start. I have a swing client that transmits XML/HTTP to and from a server, parses it, etc... I am finding that the XML/HTTP data request
is a factor of 10 to 100X slower, at least, using Java Web Start than without.
Any suggestions would be helpful
Thanks
Charles

Charles,
I've also observed some overhead when running an application deployed with JAWS compared to running the application from the jar, or in my dev environment.
After searching these forums a bit, I found this buried nugget of info: Try System.setSecurityManager(null) if you are requesting <all-permissions/> already.
Before the workaround, my application was taking 194 seconds for a single analysis run. After this workaround was applied, the same analysis run took only 82 seconds.
So as you can see, there is considerable overhead associated with performing operations through the layers of security (my guess). My particular application does a lot of disk I/O (which is probably something the security manager watches closely).
I stress the 'workaround' aspect of this because I haven't fully investigated the ramifications of using it, but eventually this might turn into a bug submission (because if I'm already requesting all-permissions, why do I still need to do setSecurityManager(null)?).
At any rate, hope this helps!

Light Flow / Accessibility Problems After Update ..

OK Light Flow problem after update.... the problem is my Talk Back in Accessibility keeps turning on after i restart my phone i know it should not do that it only dose it when i have Light Flow - LED & Notification installed and Tturned on in Accessibility ..... i use Light Flow - LED & Notification to control my LED Notification becuse i hate the built in feature that came with the phone the default management keep the LED to dim hard to see ........ i have used the app ever scene i got the phone and never had a problem tell this crappy update JZO54K.I535VRBLMD3 / I535VRBLMD3 came out i also believe the update JZO54K.I535VRBLMD3 / I535VRBLMD3 that was pushed out made the Accessibility option bad / and everything else
The phone is new
i have hard factory reset it / battery pulled
it did it with old phone but did not do it before that update was pushed
i also got a (NEW) NOT REFURBED phone trying to solve the poor 4G LTE signal /battery life
and over all phone performance with no luck that update was a bad one and needs to be addressed
PLEASE FIX THE PROBLEM >>>>> VERIZON SAMSUNG GOOGLE ( PLEASE )

yep, I had that same problem too, but found a work around. First I tried disabling the accessibility options (but that was no good, I like the light flow notifications). I read from the app (see bottom of opening screen):
I found the work around to be just getting a folder app from the play store - the only talking it was doing was "opening folder" "closing folder" (annoying as he!!)
See the second screen for what that says as far as options. My opinion - just get the folder app, it's easier.

Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query

Hi All,
There is a Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query in a report painter.
This query is working fine when executed in 4.7 system where as it is running for more time in ECC6.0.
Select query is on the table COSP.

I have checked with the table indexes, they were same as in 4.7 system.
What can be the reson for the difference in execution time. How can this be reduced without adjusting the select query.
Thanks in advance for the responses.

Hi,
ohhhhh....... lots of problems in select query......this is not the way you should write it.
Some generic comments:
1. never use SELECT
                   endselect.
   SELECT
into table
   for all entries in table
where.
   use perform statment after this selection.
2. Do not use into corresponding fields. use exact structure type.
3. use proper sequence of fields in the where condition so that it helps table go according to indexes.
    e.g in your case
          sequence should be
LEDNR
OBJNR
GJAHR
WRTTP
VERSN
KSTAR
HRKFT
VRGNG
VBUND
PARGB
BEKNZ
TWAER
PERBL
sequence should be same as defined in table.
Always keep select query as simple as possible and perform all other calculations etc. afterwords.
I hope it helps.
Regards,
Pranaya

Serious performance problems on iWeb site

Can anyone help me find the problem with peterlance.com? It looks like author Peter Lance uses iWeb to update his web site. He redesigned it recently (and did not use iWeb for the old design). Anyway, it has serious performance problems on Internet Explorer, which I was hoping you guys could help pinpoint? Is there something simple I can tell him to try to fix the problem? He is launching a new book on Tuesday so he will be getting a lot of traffic, but for now the response time is not very good. Any suggestions?
In particular, each new page seems to hang for about ten seconds and freeze using Internet Explorer 6. Any fixes?
I mean, fixes other than: "Don't use Internet Explorer!"

Welcome to the discussions, TopDog08.
There are several plain .jpg's and that's good, but you need to convert every .png on the page (or as many .png's as you can) to a .jpg. For example,
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/shapeimage46.png
Convert that to a jpg, then replace the graphic and text on the iWeb page with this converted jpg (some have has success using Downsize http://www.stuntsoftware.com/Downsize/)
The ones you won't be able to do anything about are the ones that are a part of the blog, but that will be only 5 images instead of the many you have now.

Is covering part of your menu which is why it appears that only the top half is sensitive to rolling over. You'll have to adjust your layout to account for this.
Another area to look at, there are white boxed png's surrounding the amazon book covers at the top.

Another set of .png's you'll have to get rid of. How did those get put on the page?
What you see happening with IE is a java script running to fix IE's problem with png's. The fewer .png's you have, the less of a problem with IE you have.
